Fluid in the knee joint causes and treatment. Inflammation of the synovial membrane with the further development of effusion - fluid in the knee joint: causes and treatment with effective means and methods

accumulation of fluid in knee joint- this is an abnormal pathological situation, the causes of which may be different, and therefore the consequences and complications can be expected to be very different. The only key to success with fluid buildup in the knee joint is to seek immediate medical attention. medical assistance, without which the disease can lead to irreversible consequences.

Reasons for the appearance

In some cases, fluid collects in the patella even after a bruise or hard hit that violates the integrity of the internal tissues of the joint. Because of this, the knee after the injury noticeably swells and loses mobility, causing pain to the patient. In such a situation, the consequences for the patient are not so bad. Firstly, the cause of the pathology is known, and there is no need to waste time on diagnosis, and secondly, it is easier to cope with a single injury than with an acute or chronic inflammatory disease.

It is the latter that are the most common causes of the formation of excess fluid in the cup, and in order to cure the patient, some effort will have to be made. Most often, doctors are faced with synovitis - an inflamed condition of the synovial membrane of the knee joint, and one should be well aware of what this pathology is dangerous and how to remove its root cause.

Provocative factors leading to synovitis are enough:

infectious - a disease resulting from the ingress of pathogenic pathogens from external environment(nonspecific - pneumococci, streptococci, staphylococci; specific - tubercle bacillus, treponema and others);
aseptic - reactive inflammation due to injury, damage to the synovial membrane of the meniscus or cartilage, endocrine pathology, hemophilia;
allergic - as a result of acute contact with a specific allergen.

Even not too strong, at first glance, hypothermia can lead to the formation of a synovial effusion in the calyx, which cannot resolve itself or after treatment with folk remedies, which inexperienced patients often sin. In more specific situations, fluid accumulates in the joint. For example, due to arthrosis as a result of aging of the body and wear and tear of tissues, or due to hemoarthritis - accumulation in the cup is not effusion, but blood that will have to be pumped out.

Often, the problem of the formation of excess fluid is faced by those patients who, in fact of their work, receive long-term excessive stress on the joints - athletes, workers of heavy physical labor.

Characteristic symptoms

The symptomatology inherent in the accumulation of fluid in the knee is sufficiently characteristic that an experienced specialist can draw key conclusions based on a patient's interview, visual examination and palpation. Of course, an important role in subsequent successful therapy is played by the collection of anamnesis, since it is not enough to eliminate clinical signs - it is necessary to deal with the cause of the pathology, otherwise short time the patient will relapse.

It is possible to determine what happened to the knee and what to do in the current situation, first of all, by its external state - it will be swollen to one degree or another with fluctuation compaction around the bone structure. It is quite natural that the movement of the leg in such a case will be very difficult against the background of the pronounced discomfort endured by the patient. As for the pain syndrome itself, it may not be too obvious - it all depends on the individual case and the cause of fluid accumulation. With an injury or bruise, the pain will be distinct, as with the inflammatory nature of the pathology.

The following symptoms can be considered as additional diagnostic signs:

local or general increase body temperature to subfebrile values;
redness of the knee in the joint area;
probable accession to clinical picture headaches, nausea, chills.

Therapeutic measures

It is impossible to get rid of the fluid in the joint other than to treat the disease on an outpatient basis, and in practice, a rational solution is to combine two methods of therapy - conservative and surgical: the fluid must be pumped out.

First of all, it is necessary to determine how difficult the situation is, for which ultrasound, x-rays and, possibly, a number of tests are performed.

Pumping is carried out according to the following method:

In the swollen area around patella the surgeon inserts the needle, and then the effusion or accumulated blood is pumped out with a syringe.
The procedure usually does not take much time, and is carried out under local anesthesia, so discomfort during the procedure is minimal.
Upon completion of pumping and in the following days, it is necessary to organize pharmacopuncture - regular administration of antibiotics into the patella. This will be required even in situations where the cause of the disease was not an infection.
Antibiotics in parallel can be prescribed for oral use, as well as various immunomodulators, vitamin complexes, calcium.

For local therapy, the specialist will prescribe the external use of anti-inflammatory gels, ointments or creams.

Not the last role in the successful restoration and return of former mobility is played by physiotherapy and reflexology, combined with acupressure, which will take more than one week to pass. Finally, to remove all consequences past illness you will need to practice physiotherapy exercises for months. In a number of specific situations, the following measures are likely to be used:

immobilization with plaster for a long time;
treatment of the damaged area with antiseptic agents;
a course of acupuncture.

Risk factors

First of all, those people who have already been diagnosed with arthritis or arthrosis of the joints, especially the knees, are at risk of facing such a disease. The same risk category includes patients with chronic knee problems - athletes, cyclists, lovers of an active lifestyle. To prevent the development of pathology or successful treatment on early stage experts recommend regular medical examination, protect your joints from unnecessary stress. And also seek medical help if you find any deviations from the norm.

All joints contain joint fluid. It is responsible for lubricating the joints, which prevents the bones from rubbing and breaking down quickly. In case of violation of the production of lubrication, various joint diseases develop, such as arthritis, arthrosis and others. In this case, synovial fluid may not be enough, or it may be produced in excess, which is also fraught with the development of pathology.

Articular fluid is produced by epithelial cells localized in the synovial membrane of the joint capsule. The norm is considered to be a constant volume of fluid in the synovial bag - about 2.5 milliliters. Violations of this norm in the direction of decreasing or increasing never arise on their own. A number of factors are known that can provoke a violation of synovial secretion.

The accumulation of fluid in the knee joint is not considered an independent pathology. In all cases, excessive production is provoked by injuries or the presence of an inflammatory process in the synovial bag or other components of the joint. Excessive production of fluid leads to its accumulation in the synovial cavity. An increasing swelling is formed in the area of the patella, develop painful symptoms.

Given the factors that provoked a failure in production, the composition of the liquid will change. The knee joint is one of the most loaded, therefore it is often injured and overloaded. Therefore, the risk of excessive fluid accumulation is quite high compared to other joints.

Pathology significantly reduces the quality of life, limiting the movement and activity of the patient. Diagnosis and treatment of such pathologies is carried out by a traumatologist, surgeon, rheumatologist or arthrologist. The sooner the correct diagnosis is established and treatment is started, the higher the chances of recovering quickly and without negative consequences. Also interesting to read about.

Possible reasons

The accumulation of synovial fluid in the joints may have different reasons. Often the pathological process occurs after diseases and injuries. To get rid of the pathology and prevent it reappearance it is recommended to establish the root cause and, if possible, eliminate it. The main factors causing the accumulation of excess fluid in the knee joint include:

knee injury - when falling, hitting, jumping from a height;
fractures of the bones of the joint;
torn or torn menisci ligamentous apparatus or joint capsule;
hemarthrosis;
synovitis;
bursitis;
arthritis;
Baker's cyst;
pseudogout;
rheumatism;
gonarthrosis;
Koenig's disease;
allergy;
viral infection;
benign or malignant tumor;
hemophilia.

The risk group for diseases includes the elderly, obese, athletes. Also, the accumulation of fluid can provoke prolonged physically hard work and heavy loads or heredity to pathologies.

Characteristic symptoms

Excessive production of fluid in the knee begins some time after injury. The symptoms of this process directly depend on the cause and may be different. But nevertheless, common signs are present, as a rule, they occur in all patients, albeit with different intensity:

swelling of the knee joint;
develops pain on movement;
at the site of injury, the skin overflows with blood;
heat is felt at the site of the lesion;
possible hemorrhage into the joint cavity or under the skin;
movement in the knee becomes limited.

Treatment Methods

The therapeutic course for excessive production of synovial fluid should be prescribed by a doctor. If fluid is diagnosed in, it is categorically not recommended to carry out treatment at home on your own and without the advice of a doctor, as this can lead to complications and irreversible consequences. Basically, the use folk remedies allowed, but rather additional measure to basic medical treatment.

Prescribed for drug treatment antibiotic drugs, corticosteroids, drugs from NSAID groups. Also, the doctor must prescribe a gel or ointment with an analgesic effect to relieve swelling and inflammation.

If the pathology is running, and the joint is already severely damaged, or conservative treatment does not give the desired results, it is necessary to perform surgical intervention. In this case, the synovial fluid is removed by opening the knee surgically. rehabilitation period after the operation depends on its complexity and takes from 1 month.

To reduce intra-articular pressure and prevent local ischemia, it is prescribed massotherapy. It promotes increased blood flow, which speeds up knee recovery.

Lack of joint fluid

What to do if there is no fluid in the knee joint, the doctor will be able to answer by conducting the necessary diagnostics. In any case, it will be necessary to restore lubrication in the joints, since its lack affects the health of the joint no less detrimentally than an excess.

Synovial deficiency affects the elderly. The main symptom of a lack of joint lubrication is the appearance of a crunch or creak in the knees when walking or moving. After some time, if no action is taken, unpleasant painful symptoms appear. To avoid disability, you should visit a doctor at the first signs of a pathological process in the knee joint and undergo a diagnosis.

Why is it dangerous

The lack of synovial fluid in the knee joint causes the bones that make up the joint to begin to touch. There is not enough fluid to moisten and lubricate the bone surface, which is why the bones begin to rub against each other. At the same time, the hyaline cartilage is gradually erased, an inflammatory process develops, gradually developing into a chronic form.

When moving, a person feels extreme discomfort and soreness. Progressive diseases such as osteoarthritis or different types arthritis. In the absence, it can completely immobilize, and for treatment it will be necessary to perform endoprosthetics.

What to take to recover

A positive result in the treatment of deficiency contributes to the correct lifestyle in combination with medical procedures. In the diet, be sure to include foods that contain such useful material like selenium, sulfur, proteins, carbohydrates, omega-3 acids and collagen.

It is possible to restore synovial fluid in the knee joints by taking vitamins and supplements. For example, hyaluronic acid restores the production of joint fluid. Its main function is to retain water and lubricate the cartilage tissue in the joints. The average dosage for an adult is about 200 milligrams. It is recommended to take in combination with vitamin C to enhance the effect.

Useful substances glucosamine and chondroitin are contained in chondroprotective preparations. The main constituent of synovial fluid is glucosamine, which is responsible for its viscosity.

Chondroitin enhances synovial secretion. Chondroprotectors are recommended to be taken with meals to reduce them. Negative influence to the gastrointestinal tract.

If necessary, the doctor may prescribe injections of sodium hyaluronate into the joint cavity. Since this method has a number of contraindications, it can only be prescribed and performed by a doctor in medical institution.

Each element in the human body is a unique joint that has a significant function. Speaking of the knee joint, its role cannot be overestimated, because such a complex and strong joint takes on the most severe loads every day.

At the same time, all movements in flexion and extension under weight pressure occur imperceptibly and painlessly. This effect is observed in the absence of pathologies, the presence of a smooth cartilage surface and the presence of synovial fluid in the joint, which fills the cavity.

The structure of the knee joint

Joint injuries rarely go unnoticed, as damage thins the tissues, making the joint vulnerable. In addition, exudate may appear and accumulate in it - a liquid that entails a mass unpleasant consequences. In any case, the changes do not go unnoticed and require immediate contact with a specialist.

In the human body, it is the knee joint that is considered the largest, and, nevertheless, the most traumatic. All the time, all the gravity of the mass of the human body falls on it, it participates in movement. Therefore, injuries are common.

The structure of the knee joint

The joint itself is formed from the surface of the cartilaginous tissue, which is responsible for the proportionality of the joints, namely:

lateral;
medial;
also has a meniscus.

Inside the joint there is a fluid called synovial fluid. It saturates and coats the surfaces of the joint, preventing premature wear. However, over time or with an unscrupulous attitude towards own health, injuries in the joint can develop not only the consequences of injuries, but also diseases.

The most common among diseases of the knee: arthritis, arthrosis, bursitis, synovitis, osteoarthritis.

What is synovitis?

Synovitis is an inflammation of the synovial membrane, which is the name of the place where fluid accumulates in the joint. The accumulation of fluid in the membranes is essentially a consequence of the disease synovitis.

As a rule, the root cause can be:

Injury.
Infection.
Allergy.
Disease of the endocrine system.
Metabolic disorders, etc.

Synovitis of the knee

The development of the disease of synovia begins with the fact that it collects a large amount of effusion, everything is accompanied by a painful sensation, while there is a limitation of joint mobility. If the fluid is collected only in the upper part of the knee in the region of the calyx, then they speak of suprapatellar synovitis.

With the development of this disease, not only the knee joint itself can be affected, but also the wrist, elbow, ankle and others.

Where does excess fluid in the knee come from?

The appearance of excess fluid in the cavity can be observed due to:

Accumulation of hemorrhage due to trauma in the meniscus.
In case of damage to the ligaments, their rupture or sprain.
At fracture.
With cracks.

In addition, endometrium can develop in the joint. Swelling, swelling and a sharp change in body temperature can indicate the formation of fluid in a sore knee.

Lack of synovial fluid

In addition to excess and accumulation of fluid in the knee joint, there may also be a lack of synovial fluid. At the same time, intra-articular injections are made into the knee, that is, synovial fluid arthroplasty is performed in order to restore the shortage and normalize the volume of lubrication.

The decrease in the volume of this liquid is due to:

Synovial fluid prosthesis

Decreased protective properties of immunity.
Infectious diseases that focus on the rapid rate of fluid withdrawal.
Flaw water balance in the body.
Wrong diet and wrong lifestyle.
Super-strong loads on the body, as well as on the joint.

Also, an insufficient amount is observed as the body grows or ages. As a rule, over time, in the body of older people, the production of hyaluronic acid decreases and stops completely.

Other symptoms

Before exudate begins to accumulate, the damaged joint begins to “make itself felt” with dull aching pain, complications during movement. In the area of damage, it swells, in the affected area the temperature rises.

At the same time, it may increase headache, the code turns red, seals form. From this moment on, we can say that fluid begins to accumulate in the articular sac.

Signs of Fluid Buildup

Causes

Why does fluid accumulate in the joint? The method of treatment is determined by the diagnosis. The cause of fluid accumulation can be determined by considering a particular etiology. Fluid can accumulate due to diseases that affect the knee.

Causes of fluid accumulation	Manifestation and signs
Cracks, fractures in the bone	Pain syndrome, fever, swelling in the joint
meniscus injury	Swelling, enlargement of the joint
and	Soreness, fever, redness of the skin, decreased motor function
Damage to the integrity of the joint capsule	Joint enlargement, pain
Hemarthrosis	Discharge of blood in fluid instead of effusion
	Isolation of purulent exudate in wounds and bruises of the knee
	Inflammation of an infectious nature that occurs in the periarticular bag.


	Inflammation against the background of an allergic reaction, infection and stress on the same muscle group.
	It develops against the background of the aging process, as the joint wears out.
Tumors	Swelling stiffness in double vision
pseudogout	Pain syndrome, swelling

Causes of fluid accumulation in the knee joint in a child

Regardless of age, knees can be prone to injury. What can we say about children whose knowledge of the world occurs through an active motor function. Frequent movements, maximum, for their age, loads lead steadily to injuries.

As a rule, in children, pain and accumulation in the knee joint occurs due to the active growth and development of the whole organism, as well as against the background of injuries of various kinds.

Most often, the causes of accumulations in the joints can be:

Schlatter's disease of the knee

in connection with deformations;
fractures;
dislocations;
development of diseases (Osgood-Schlatter);
stretching muscles and tendons;
severe tissue damage and other.

Diagnostics

Fluid is a consequence of the development of a particular problem. When contacting a specialist, the primary source is determined for further diagnosis and determining the treatment regimen.

First of all, they are appointed:

x-ray, which shows the presence or absence of cracks, fractures, destruction or development of arthritis.
MRI, which allows you to determine even the most insignificant defect or anomaly in the joint, as well as the surrounding tissues.
Ultrasound procedure, which diagnoses the cause of swelling, causes of pain spasm. At the same time, using ultrasound, you can determine the presence of arthritis and disease of the ligaments and tendons.
Analysis of blood and urine. These studies allow us to talk about the presence or absence of infections. For example, with the development of Lyme disease, only a blood test can accurately indicate the problem. You can also learn about various kinds of inflammation, the development of such a disease, as well as other things.
Arthrocentesis or aspiration in the joint. This action allows you to suck and pump out the fluid from the joint, and then take it for further research in order to find bacteria, microorganisms, acid crystals or blood in it.
Arthroscopy. Carried out under the supervision of a specialist, in the form of a small surgical intervention. A special device is inserted into the joint, which allows the doctor to examine the surface of the tissues and take tissue materials for examination.

Arthrotomy

Which doctor treats synovitis?

Joint problems are primarily treated by a general practitioner. It is from his reception that the patient begins to turn to the surgeon, and then to be treated by an orthopedist. The surgeon will help remove excess fluid and get rid of associated symptoms.

Treatment Methods

In practice, they use drug therapy and surgical treatment.

This method is based on the indications of clinical studies and includes the use of such drugs:

Non-steroidal anti-inflammatory drugs. These include Ibuprofen, Lornoxicam, Ketoprofen and others.
Antibiotic therapy, which is used in the presence of infection. The course of taking antibiotics is very long.
Hormones of the corticosteroid group. This group includes substances that have an anti-inflammatory effect - Methylprednisolone, Dexamethasone.

Surgery is necessary to remove the accumulated excess fluid from the joint cavity.

Joint immobilization

If the meniscus in the joint is damaged, it is necessary to carry out such a procedure as immobilization of the joint. It is a fixation of an injured place due to a splint or an orthosis on the knee, while gypsum is not applied. Then they take preparations of the non-steroidal group, undergo a study on an x-ray machine.

Surgically, immobilization occurs by stitching and removing detached particles.

Immobilization is an unpleasant and lengthy procedure. The necessity of the procedure is that after fixation, the load on the joint is removed, respectively, further injury and rupture are minimized. This is especially true in adolescents and children, who are often hypermobile.

As soon as the specialist decides on immobilization, measures are taken:

Medicines

Conservative treatment involves the use of several groups of drugs.

Non-steroidal anti-inflammatory drugs, which relieve inflammation and the main symptoms:

Aspirin.
Analgin.
Diclofenac.

Diclofenac Ketoprofen in the form of a gel Aspirin Analgin

Taking drugs that lower the temperature, caused by inflammation

Paracetamol.

Ibuprofen for pain relief Indomethacin in the form of suppositories Paracetamol

Antibiotics are used to fight suppuration and infections.

Antibiotics from the group of cephalosporins or glycolipids can be used:

Cefoxime.
Ceftriaxone.
Cefotaxin.
Vancomycin.
Nimid.

Nimid Cefotaxime Ceftriaxone Vancomycin

The joint is smeared Fastum or Voltaren-gel. Use of antihistamines Tavegil or Supradin. Multivitamins are used to restore health.

Physiotherapy

Physiotherapy occurs only after receiving all clinical tests.

It includes physiotherapy activities that are aimed at strengthening the muscles and ligaments of the joint:

phonophoresis and electrophoresis using the drug Hydrocortisone;
UHF and paraffin applications on the joint;
heating and ozocerite applications.

Surgery

If a alternative methods treatments do not lead to positive result, the doctor decides to carry out therapy surgically.

Fluid is removed from the knee joint by inserting a needle into the joint. The needle has a special hole and diameter, therefore, without prior anesthesia, such manipulations are not carried out.

Invasive surgical procedures related to the surgical methods of solving the problem include:

Arthrocentesis. This procedure involves the removal of excess fluid from the cavity, due to which relief of pain and swelling is observed. After such an intervention, a corticosteroid hormone can be pumped inside, which prevents the development of the inflammatory process.
Arthroscopy. It is carried out in order to eliminate the gap. During the procedure, a small piece of equipment is inserted.

Operation arthroscopy

Before the pumping procedure, the strongest in the group are introduced into the body. analgesic drugs, anesthesia. After receiving the material, they conduct a study.

Based on these data, it is possible to speak objectively about the root cause and choose the necessary treatment in order to exclude the development of relapse in the future. In this case, the swelling is removed after the excess fluid is pumped out of the knee.

Folk remedies

To some extent, a positive event. With the right attitude, you can stop the pain, reduce inflammation. However, without eliminating the root cause - that is, without proper traditional treatment, a positive effect cannot be achieved.

For the treatment of problems in the knee joint, drugs such as:

Oil from bay leaves. Such oil is prepared from a mixture of crushed bay leaf boiled in 200 g of vegetable oil. The infusion is left for 7 days in a dark place. Lubricate the damaged area at least three times a day.
Ointment from comfrey. This tool is made independently from grass - comfrey. For cooking, I need to chop the grass, add about 200 grams of lard to such a porridge and leave it in a cold place for 5 days. After the mixture is infused, rub the knee in the morning and evening. An elastic bandage is applied on top.
A decoction of rye. To prepare a decoction, boil 100 g of grains in 1 liter of liquid for at least 20 minutes. Then add 200 g of vodka, 10 g of barberry and 500 g of honey to the mixture. The drink is infused for at least 14 days in a dark, cold place. Take it three times a day, 60 ml.

What threatens the accumulation of fluid in the knee joint?

Diseases of the joints inevitably lead to the fact that they become susceptible, brittle. In addition to limiting motor function, neoplasms occur, which sometimes lead to fatal consequences.

As a rule, the accumulation of fluid is often a consequence of infection. Once in the joint, any kind of infection affects it, resulting in irreversible negative complications in the form of complete destruction of the joint. Therefore, it is necessary to quickly cure sore knee.

First of all, among the most frequent consequences accumulation of fluid, cartilage begins to break down, which threatens to gradually move to bone tissue. This causes the loss of the ability to walk, leading to disability. In medical practice, there have been cases of development septic shock in which there was a lethal outcome.

Peripheral or flaccid paresis

Is it possible to pump out fluid from the knee joint at home?

Self-medication does not lead to a positive result. It is impossible to eliminate the primary source of the disease on your own, without carrying out clinical examinations. Spontaneous leakage of fluid is very rare.

The indications for pumping out exudate are the following symptoms:

Pus.
Hematoma or.
The need to rinse the cavity with an antiseptic.
Administration of an antibiotic.

Moreover, it is impossible to pump out the fluid that has accumulated inside the joint on your own. In classical medicine, it is removed by a puncture, that is, a puncture of the articular bag. An opening of the joint may also be performed.

In any case, the liquid must be removed immediately, and at home to do everything quickly and without consequences is not possible and can simply be dangerous.

How much does it cost to drain fluid from the knee joint?

The cost of the operation to pump out the accumulated exudate in the knee joint in Moscow clinics:

Clinic "Miracle Doctor" - 990 rubles.
"On Clinic" - 1900 rubles.
"Sm-clinic" - 2100 rubles.

Pumping out liquid in St. Petersburg will cost:

"MC dynasty" - 2500 rubles.
"First family" - 1740 rubles.
"Family doctor" - 1650 rubles.

standard procedure depending on region of Russia the cost of exudate pumping has a price range from 850 rubles to 3750 rubles.

The problem that is raised in this article is very relevant at any time, under any conditions, standard of living. It can be encountered in absolutely any place, with different conditions, or even not notice its appearance.

The purpose of this article is to help in the detection, prevention and treatment of diseases in which fluid accumulates in the knee joint, knee pain, joint swelling.

The information contained in the article will be useful to all its readers, without exception. After all, diseases of the knee joint can overtake everyone and it does not always depend on the physique, lifestyle or financial situation. In the same way, the manifestations of these diseases can be absolutely unique, although they have similar symptoms.

The structure of the knee joint

Fluid in the knee joint

The knee is the largest joint in the human body. During walking, the entire body weight acts on the knee. It is for this reason that injuries in the knee area can often be found in traumatology. As a rule, all diseases of the knee joint are the result of all kinds of falls, injuries or heavy load on the joint. One of them is fluid in the knee joint or synovitis.

Under influence various diseases or injury, fluid may accumulate in the knee joint. With this pathology, it is necessary to consult a doctor as soon as possible and begin treatment. Otherwise, it will break motor function lower limbs.

The normal functioning of the knee joints is ensured complex mechanism functioning of the musculoskeletal system. Accumulating fluid in the knee joint can partially or completely limit its movement, as well as cause significant physical pain. It is necessary to solve the problem quickly, otherwise there is a risk of irreversible processes and disability.

Often, a complication of a knee injury can manifest itself in the form of accumulation of fluid in the knee joint, with the occurrence of swelling of the joint, swelling varying degrees and pain syndrome, it can be said with almost 100 percent certainty that fluid has appeared in the knee.

In such situations, treatment consists of creating the necessary conditions for complete rest of the damaged joint by fixing it with a bandage or patch. When, nevertheless, synovial fluid accumulates in the knee joint, it is usually removed by the surgeon with a syringe. This uses local anesthesia.

Fluid in the knee joint can be clear, cloudy, or bloody. In addition, the intensity of pain will depend on the degree of damage to the knee.

Often, the accumulation of fluid in the knee joint is the result of injuries, falls or overloads. Synovial fluid is abbreviated as synovia because it appears in the synovial membrane. For this reason, the scientific name for this disease is synovitis. The disease is quite dangerous, treatment must be started immediately.

Fluid in the knee joint, the reasons for its appearance

The fluid accumulates, first of all, after suffering overloads, injuries or unsuccessful falls. Most often, the injury occurs from a regular knee strike or after jumping from a great height.

The bones, muscles and tendons that form the knee joint are covered with a special membrane - the synovium. It is practically impenetrable, serves as a kind of shock absorber that protects the joint from damage, and ensures its physiological mobility.

The cells that cover the synovial membrane secrete a liquid lubricant into the joint space, which ensures the free operation of bone and cartilage surfaces. If such a fluid is produced more or less than the norm, there are physical pain different intensity, occur pathological changes cartilage and bone tissues of the knee.

There are several main factors that cause synovial fluid in the knee to be secreted in greater volumes than necessary. Experts identify the following reasons:

trauma;
inflammatory processes of an infectious nature;
malignant neoplasms;
osteoarthritis;
allergic (immune) reactions;
gout;
blood clotting disorder.

The accumulated fluid may be cloudy or clear, have various colors(white, red, pink, yellow). It all depends on the cause of the synovitis. Turbid, yellowish liquid indicates the infectious nature of the inflammation, pink or red color indicates a hemorrhage inside the synovial cavity due to injury or bleeding disorders.

The complex structure of the knee joint, the heavy loads it experiences, makes it vulnerable. Sports, potentially dangerous species work, accidents are common causes of injury. After a knee injury, fluid accumulates inside the synovial membrane for 2-3 days.

Osteomyelitis, bone tuberculosis, bacterial sepsis are infectious causes through which fluid accumulates in the knee joint. Bacterial damage to the knee joint can occur as a result of an open or closed injury. Rheumatoid arthritis, bursitis and gout cause physiological changes work of the knee joint, causing the formation of significant volumes of fluid in the synovial membrane.

Malignant tumors and sarcoma, which are localized in the bone and cartilage tissues, cause significant changes in the function of the knees and become the causes of the appearance of fluid. Fluid in the knee joint may appear due to an inadequate reaction of the body in response to the penetration of an allergen or an autoimmune process. Violation of blood clotting, including in hemophilia, leads to the filling of the synovial cavity with a red liquid.

General symptoms

Typically, symptoms of fluid in the knee after an injury include:

sharp, aching Blunt pain in the knee;
swelling in the joint, pronounced or barely noticeable;
stiffness of movements: with large cluster liquid is difficult for a person to move, the leg cannot be bent;
the size of the knee increases;
body temperature rises;
a seal appears under the skin in the joint area;
the skin turns red;
headaches and chills are possible if the infection caused the pathology.

But chronic synovitis is characterized by less pronounced pain. In other words, the joint is filled with fluid gradually. That is why with a long-term course of the disease, deforming arthrosis may appear.

In addition, there is also reactive synovitis of the knee joint, which is considered an allergic type of this disease and is caused by mechanical or toxic influence and often acts as a manifestation of an allergic reaction.

Crunch in the knee

Let's talk about such phenomena as soft clicks and crackles in the legs, which then become louder and sometimes accompanied by painful sensations. Therefore, you need to think about what to do with a crunch in the knee immediately after its appearance. Generally, the sooner treatment for a crunchy knee is started, the more likely it is to be effective.

The causes of a crunch in the knee joint may be the consequences of a joint injury or cartilage damage, salt deposits, beriberi, endocrine disorders, increased mobility of the head or general instability of the joint.

Sometimes a crunch appears as a result of a violation of congruence, i.e. the exact coincidence of the articular surfaces, as a result of which they can touch, making characteristic sounds.

To correct the incorrect position of the articular surfaces, you need to contact a specialist; independent attempts to straighten the knee joint can lead to serious injury or even disability. A crunch in the knee can be one of the symptoms of arthritis or arthrosis, as well as pathological salt deposits.

Prevention of a crunch in the knee is primarily in the right balanced diet and prevention of mechanical damage to the knees. In case of injuries and sprains of the knee joint, it is imperative to apply a fixing bandage to the damaged joint, otherwise it can later lead to displacement of the articular surfaces or the development of increased mobility and instability of the joint, which in turn is usually accompanied by a crunch in the knee.

Diagnosis of pathology

If there is an accumulation of fluid, then treatment is started only after establishing a picture of the origin of the pathology. To do this, it is necessary to carry out a series diagnostic studies which include examining the limb, taking an anamnesis, questioning the patient and instrumental (hardware) examinations. The data obtained with their help help to reliably determine where the fluid in the knee joint is localized, to identify the causes and treatment of the pathology.

The most informative diagnostic tools are:

radiography of the knee;
ultrasound procedure;

Patients also need to donate blood laboratory research, and sometimes go through an aspiration procedure, that is, pump out fluid from the affected knee to determine its composition.

Reactive synovitis

This form is considered as a secondary synovitis that has arisen against the background or as a complication of another disease. In fact, this is an inadequate allergic reaction of the body, which appears due to mechanical or toxic effects on the affected joint.

Therefore, treatment for a diagnosis of reactive synovitis is aimed at eliminating provoking factors.

The reasons for this reaction of the body may be other diseases of the knee joint:

With gonarthrosis, synovitis of the knee joint can be observed as a moderately severe complication already in the second stage of the disease. In such a situation, doctors try not only to eliminate the accumulated fluid from the joint, but also to make every effort to regenerate damaged joint tissues.
Synovitis of the knee joint is quite common in arthritis. The inflammatory process in the joint, caused by autoimmune or metabolic failures, is almost always accompanied by fluid accumulation at times of exacerbation.
Synovitis and bursitis of the knee joint are considered paired diseases. Bursitis is a narrower concept of inflammation that extends directly to the bursae. With inflammation of the articular bags, synovitis acts as the main symptom of the disease. The most pronounced synovitis of the knee joint is observed with superapatellar bursitis, when the synovial membrane over the patella becomes inflamed.

The synovial membrane can also become inflamed due to:

allergic reactions;
atopic dermatitis;
eczema, hemophilia;
autoimmune conditions;
endocrine pathologies;
metabolic disorders.

Post-traumatic synovitis

Synovitis, which occurs as a consequence of joint injuries, is a common clinical picture.

The synovial membrane can become inflamed:

with damage to the meniscus;
after rupture of ligaments;
due to direct or sliding impact;
after dislocations or subluxations of the knee;
in the presence of microcracks in the joint;
with fractures;
due to scratches, wounds of superficial tissues.

In the treatment of post-traumatic synovitis, attention is paid to restoring the integrity of the damaged parts of the joint. Post-traumatic synovitis is characterized by acute course diseases. Inflammation resulting from chronic injuries proceeds as moderate synovitis.

Exudative synovitis

This disease is associated with instability of the knee joint. With instability, movements are not carried out in full, which provokes irritation of the synovial membrane and, as a result, exudative synovitis with a significant accumulation of exudate.

This form of synovitis occurs:

with knee deformation after injuries, as well as degenerative processes caused by rheumatism, gout;
with ligament insufficiency, which appeared as a genetic anomaly or due to low joint mobility;
with direct trauma to the joint, when the blow is directed perpendicular to the articular surface;
with a meniscus injury that provoked irritation of the synovial membrane.

Treatment of exudative synovitis of the knee joint is aimed at restoring the stability and motor abilities of the joint.

Infectious synovitis

Infections most often penetrate the joint due to injuries. The synovial membrane reliably protects the joint from infection. The slightest damage "opens the gate" for infection.

Infections can enter in various ways:

contact - through damage to the skin;
hematogenous - through the bloodstream if the patient has infections in the body;
lymphogenous - along the lymphatic channel.

Infection occurs with both pathogenic and conditionally pathogenic particles:

streptococcus;
staphylococcus;
pneumococcus;
tuberculous microbacterium.

Provoke inflammation in the synovial membrane can and viral infections. So, synovitis can be a consequence of influenza, SARS.

Symptoms of the acute stage of the disease

The inflammatory process can develop both over the course of several days, and be quite rapid and manifest itself within a couple of hours.

The first sign is an increase in the volume of the joint, in which the contours of the knee are smoothed out. The process is associated with the accumulation of fluid various etiologies in the cavity. The severity of swelling depends on the volume of accumulated fluid. Visually, there is a slight increase in the knee.

Such hallmark helps to differentiate the disease with hemarthrosis, in which the increase in the knee joint occurs rapidly in just a matter of minutes and there is significant swelling due to accumulated blood.
In acute synovitis of the knee joint, the motor abilities of the knee are impaired. Restriction of movements is provoked by swelling and pain. Despite this, the patient is able to lean on the affected limb and perform flexion movements.

Minimal knee synovitis can generally be painless. Most often, the pain is not intense in nature, but is perceived by the patient in the form of discomfort with unpleasant pulling or dull sensations. Soreness is manifested by palpation of the affected area. With such inflammation, there are no local changes in the color and temperature of the skin of the joint.

With a purulent form of synovitis, the symptoms are expressed:

pulsating, bursting painful sensations;
the appearance of fever;
general malaise, accompanied by weakness, loss of appetite, muscle and headaches;
significant swelling of the affected joint;
painful movements;
hyperemia of the skin over the site of pathology;
local temperature increase.

The disease usually affects one of the joints. Bilateral damage can be observed with an infectious or autoimmune origin. With absence adequate treatment acute synovitis of the knee joint can become chronic.

Symptoms of the chronic stage of the disease

Chronic synovitis of the knee rare view, among other types this disease. It occurs as a result of an undertreated acute form or chronic instability, deformity of the knee joint.

Patients observe symptoms in the form of:

general weakness;
rapid fatigue when moving;
minor restrictions on the motor capabilities of the knee;
intermittent aching pain.

Puffiness may not be visible at all in the chronic form or have a slight manifestation. If you do not start urgent treatment of chronic synovitis, over time the disease progresses and causes complications.

Due to the constant accumulation of a liquid substance that does not have time to resolve, hydrosis occurs. With prolonged chronic dropsy, secondary pathologies develop in the form of sprains, joint instability, subluxations and dislocations. Under the influence of inflammatory fluids, the synovial membrane undergoes secondary sclerotic, morphological changes. The loss of their functional abilities of the synovial membrane leads to an aggravation of the pathological process.

As a result, the articular surfaces are destroyed, synovitis special forms changes requiring surgical intervention.

synovitis in children

The clinical picture of synovitis of the knee joint in a child practically does not differ from the pathology in adult patients. However, children's synovitis is characterized by a more rapid development with severe degrees of damage. This is due to the characteristics of a growing organism with a more accelerated blood flow and metabolism.

Therefore, it is important to start treatment of synovitis in children at the first suspicion of the disease.

Types of pediatric joint pathology are associated:

with high frequency injuries;
with infectious diseases;
with allergic reactions;
with violation of metabolic processes.

AT separate view emit transient synovitis in children, which is considered passing. It occurs in babies from 1.5 to 15 years. It is characterized by pain on movement and severe lameness. However, the disease tends to pass within a week without causing serious complications.

Doctors characterize this type of disease as a natural immune response of babies to infection. respiratory tract. Although until the end of the disease remains unexplored.

When infected with viral infectious diseases, the child's immunity is activated, resulting in attacks on the joint with temporary inflammatory process. At the same time, during the diagnosis, excess fluid is clearly observed.

Pain and lameness disappear 3-4 days after the exacerbation. If the symptoms do not disappear for more than 7 days, additional studies are required.

Forecast

The prognosis for synovitis depends on the following factors:

the general condition of the patient's body;
the level of pathogenicity of the microflora, if the form is infectious);
whether treatment was undertaken in a timely manner.

Recovery may be complete. The patient may retain joint mobility. This outcome is most often observed with a disease of the serous and allergic type.

But it is also possible to limit the mobility of the joint or a complete loss of the possibility of movement. With a purulent form of the disease, a threat to the life of the patient is sometimes created, as sepsis develops.

Surgical treatment

There are several ways to treat conditions associated with fluid accumulation in the knee. Treatment must necessarily eliminate the causes and symptoms of the disease. What to do in each case, the attending physician should determine based on the results of the examination and diagnosis.

How to get rid of fluid in the knee? A special needle is inserted into the joint, and the fluid is pumped out with a syringe. It is quite difficult to pump out fluid without anesthesia. The patient is preliminarily injected with powerful analgesics or local anesthesia. Then the obtained material is studied. Even if the pathology is not infectious.
Based on the results of the analysis, the doctor will draw conclusions about what pathological processes caused the formation of fluid.

He then decides which therapy to prescribe in order to prevent recurrence in the articular structures. Puffiness of the legs is removed after the release of the knee from the pathological fluid.

With a significant amount of fluid and a change in the structure of the joint, conservative treatment is not always effective. For this reason, the doctor may decide to perform such a procedure. If the fluid has deformed the joint, prosthetics are performed. The main treatment for fluid in the knee joint is to remove the fluid from the damaged joint.

The procedure is performed in the operating room, usually without anesthesia. The doctor gently inserts a thin special needle into the cavity of the affected joint, in which fluid has accumulated and is sucked off with a syringe. When the procedure is completed, antibiotics are injected into the vacated cavity, regardless of whether an infection is suspected.

After the operation to remove the fluid, the patient is placed in the ward to ensure complete rest of the joint, this is done with a pressure bandage or knee brace.

Further treatment The occurrence of fluid in the knee joint is the use of anti-inflammatory drugs, of which Voltaren and Diclofenac are the most effective in our opinion.

In addition, in the process of treating fluid in the knee joint, doctors eliminate not only inflammation, but also the main cause of its occurrence. Only a narrow specialist can establish an accurate diagnosis: an orthopedist or a rheumatologist, because if the root cause of the inflammation is not found, the fluid will soon appear again, and the treatment will have to be performed all over again.

Medical therapy

Drug therapy in the treatment of synovitis of any etiology is used to eliminate symptoms, as well as to relieve inflammation. It is worth noting here that the decision on how to treat fluid in the knee joint with medicines is made solely by the doctor based on the results of the examination.

In most cases, patients are prescribed certain groups of drugs. NSAIDs - for pathologies of any origin. They help relieve swelling and pain. Ibuprofen and Diclofenac are considered the most effective. As well as oral forms it is recommended to use an ointment that contains these drugs.

Antibiotics are used when the synovial fluid contains pus. Since it is possible to get rid of inflammation caused by microorganisms only with the use of similar drugs, they are prescribed orally, in the form of injections or for direct injection into the knee joint after the fluid has been pumped out. The specific type of antibiotic is determined after bakposev to identify the sensitivity of the microorganism to certain substances.

Anti-inflammatory corticosteroids (glucocorticoids) help relieve inflammation and limit the influence of the underlying pathology on the formation of excess fluid in the knee. The most commonly prescribed drugs are Dexamethasone, Prednisolone and Triamcinolone.
Antihistamines are prescribed only when the accumulation of synovial fluid is directly related to severe autoimmune disease or rheumatoid arthritis.

Any drug can be taken after it has been approved by a doctor. This happens in most cases after the liquid fraction has been pumped out of the affected joint.

Surgery

If the damage to the synovial cavities has reached its maximum and there is a danger of their rupture, as well as if conservative methods of therapy are ineffective, the patient can be referred for arthrocentesis - the procedure for opening the bursa and pumping out fluid using a special syringe with a needle.

The first question patients ask when they are referred for this procedure is whether it hurts to remove fluid from the knee joint. Everything takes place under local anesthesia, since it will be very painful to remove the fluid through a puncture without using it. During the operation, the patient does not feel pain, but as the bursa empties, he may notice a decrease in pressure inside the knee, especially if there is purulent inflammation.

Next, the doctor injects drugs into the joint bags with a syringe, since removing the fluid is not the only goal of the operation. Corticosteroids or antibiotics placed inside the inflamed bursa help to quickly cope with the pathological process.

When the process has gone far, due to which the joint deformity occurred, the patient is shown prosthetics of the joint or its individual elements (depending on the degree of deformation).

Conservative treatment

Conservative treatment aims to stop the symptoms of fluid accumulation in the knee joint, and in case of infectious and allergic diseases - to eliminate the causes of the pathology. The list of medicines is determined by the doctor.

Symptoms of pain, as well as inflammation, can be removed with the help of drugs from the group of non-steroidal anti-inflammatory drugs. Preparations of ibuprofen, paracetamol, diclofenac, ketoprofen, indomethacin eliminate pain, inflammation, reduce temperature.
Antibiotic treatment effectively eliminates purulent inflammation. Preparations with antimicrobial action are prescribed after determining the sensitivity of the bacteria that caused the pathology. A culture of material taken from the affected joint should be done. This will allow you to choose an antibiotic with maximum efficiency and quickly cope with the disease.

Treatment antihistamines used when the cause of the appearance of fluid in the knee joints is associated with autoimmune diseases, rheumatoid arthritis. Use suprastin, tavegil. AT severe cases you can make injections of glucocorticoid drugs: dexamethasone, prednisolone, betamethasone. Sometimes these injections are given directly into the joint.

Drugs from the group of non-steroidal anti-inflammatory drugs relieve inflammation and symptoms of the disease.
Ibuprofen, Paracetamol, Indomethacin will lower the temperature, eliminate pain and inflammation.

Antibiotics eliminate purulent inflammation. For example, Nimid. It is an analgesic and anti-inflammatory drug. It is used up to 4 times a day. Contraindicated in pregnancy and lactation. You can also rub your knee with Fastum and Voltaren-gel ointments. They also contain antibiotics.

Means with antimicrobial action are prescribed after determining the sensitivity of the bacteria that caused the accumulation of fluid in the knee. From the affected joint take bakposev material.

Antihistamines are used if fluid in the knee is due to autoimmune diseases(Suprastin, Tavegil).
Taking immunostimulating drugs, vitamins, calcium.

A buildup of fluid in the knee joint may be a symptom dangerous diseases. Self-medication is contraindicated.
It threatens the possibility of the formation of a chronic form, and that will cause complications and, possibly, disability.

Yulek26 (Tver) 10 days ago

Sonia, what country do you live in? .. They sell on the Internet, because shops and pharmacies charge a brutal markup. In addition, payment is only after receipt, that is, they first looked, checked and only then paid. And now everything is sold on the Internet - from clothes to TVs and furniture.
