How to treat excess and insufficient joint fluid in the knee joint

A complex approach

The joints do not have a direct blood supply. Their nutrition is provided by synovial fluid. It is a thick but elastic substance that reduces friction and prevents wear and tear of cartilage. Lack of fluid in the knee joint leads to a deterioration in the functions of the musculoskeletal system in general. There is creaking, clicking, and morning stiffness. Over time, intense pain in the knee develops, and degenerative changes increase. Without timely treatment, a person experiences difficulty moving. The quality of life deteriorates significantly, even to the point of disability.

Fluid in the knee joint: causes and treatment

Knee diarthrosis is the second, after the hip, in size and importance in the human body. When moving, it takes on the entire weight of the body, therefore it is susceptible to wear, destruction and injury like no other. Traumatologists daily encounter knee problems in patients caused by illnesses and injuries, stress and falls. One of the serious problems is considered to be synovitis - the collection of effusion in the diarthrosis cavity. And if there is additional swelling, pain and swelling, we can say with complete confidence that excess joint fluid has accumulated in it. The special term “synovitis” itself comes from the direct name of the lubricating thicket of the joints – synovium. It is considered a rather dangerous disorder, and in case of it it is better not to postpone a visit to the clinic. It won’t hurt to figure out why synovitis occurs, how to fight it, what measures to take and what it threatens.

Signs that synovial mass is accumulating in the limbs

If fluid collects in the knee joint, symptoms vary depending on what disease is causing the synovitis. But there are so-called general symptoms:

swelling in the area of diarthrosis of varying degrees;
redness;
local swelling;
increase in the size of the knee relative to the second;
pain of various types;
restriction of movement, it becomes difficult and painful to move the leg;
compaction palpated in the joint area; in the popliteal region;
temperature;
chills.

Of course, it is impossible to determine synovitis based on the last three signs. They are taken into account only if there are others, more “closer” to the knee - local edema, swelling, etc. Signs of this pathology tend to appear not immediately after an injury or illness, but after several hours or even days.

Drug therapy

In the treatment of pathologies of the musculoskeletal system, doctors are rarely faced with the question of how to restore synovial fluid in the joints. If the need arises, then the patient has already been diagnosed with a certain degree of destructive and degenerative changes that do not allow the person to lead a usual active lifestyle. An integrated approach to treatment is practiced, which consists of relieving pain and inflammation in the joint and eliminating swelling. The therapeutic regimen includes NSAIDs, glucocorticosteroids, analgesics, and antispasmodics. Chondroprotectors and injection preparations with hyaluronic acid are used as pathogenetic and etiotropic agents. Such a comprehensive effect on the affected joint ensures the gradual restoration of the required volume of synovial fluid.

Reasons why synovitis may develop

Limbs are often injured and suffer from excessive stress of various origins. And they react to some injuries by accumulating fluid in the knee joint. Treatment will depend on what exactly caused the synovitis. Among the traumatic root causes of its formation are: fractures of the components of the articulation, ruptures or other damage to the diarthrosis ligaments, internal hemorrhage in it, and meniscal injury. Diseases that cause the accumulation of synovium may be the following:

arthritis
is an inflammation of diarthrosis caused by injury, infection, immune disorder, permanent stress, mental trauma. It often occurs in people who are overweight, sedentary, eat poorly and live in environmentally unfavorable areas;
bursitis
– occurs after injury and infection. With bursitis, the synovial bursa becomes inflamed, the dysfunction of which causes the accumulation of effusion. Bursitis most often affects those who, by profession, frequently and heavily load certain groups of diarthrosis;
arthrosis
– occurs as a consequence of natural aging or injury. There are two stages of arthrosis: the first - when the volume of the lubricating mass decreases and the joint suffers from its insufficiency, and the second - when the volume, on the contrary, increases excessively and entails swelling of the affected area.

Inflammatory processes leading to the accumulation of water can be of three types:

Immune

Purulent.

Aseptic.

Diagnostics

A simple examination by a doctor is not enough to make a diagnosis. However, anamnesis and palpation allow the specialist to draw preliminary conclusions. The condition requires a complex of studies, including instrumental and laboratory techniques.

To assess damage to the joint capsule and knee joint, use:

Clinical and laboratory diagnostics
. Determination of the level of leukocytes, as well as the release of C-reactive protein, makes it possible to identify the fact of inflammation and determine its intensity. Additionally, specific studies are indicated: for rheumatoid arthritis (ACCP, rheumatoid factor), for ankylosing spondylitis (HLA-27B) and others. General blood and urine samples are indicated.
X-ray
. Allows you to examine the condition of the knees and identify some of the root causes: sacroiliitis, osteoporosis, arthritis. In most cases, radiography is not enough to obtain the correct result. The result does not contain soft tissue data.
Ultrasound diagnostics
. A safe non-invasive method that allows you to study the joint, ligaments, cartilage and bursae. Allows you to detect pathologies in the early stages.
MRI of the joint
. The advantage of the technique is the assessment of the state of the joint not only from the outside, but also from the inside. It has a minimal list of contraindications. It is considered the most informative diagnostic tool.
CT
. Allows you to obtain an accurate image superior to X-rays. For objectivity of the result, it is sometimes performed with contrast. The injection of a contrast agent helps detect even small changes.
Goniometry
. Allows you to evaluate the range of motion of the joint, which has changed due to lack of fluid.

What role does the synovia perform?

The knee contains a synovial membrane - a strong and impenetrable substance that envelops and covers the bone tissue and tendons. The synovial mass in knee diarthrosis plays the role of a protector against aging and rapid wear due to constant friction. The membrane cells secrete this liquid and it covers the entire surface of the diarthrosis and prevents the rubbing of its elements. If there is a lot of this lubricant or, conversely, a little, this is considered a pathology. Important: any disturbances in the production of joint secretions can be detrimental to the health of diarthrosis and require immediate treatment.

Injection of hyaluronate

For liquid intra-articular prosthetics, preparations with hyaluronic acid are used, injected into the cavities of damaged joints. The biologically active substance hyaluronate is one of the main components of synovial fluid and extracellular matrix, the presence of which determines the degree of plasticity of cartilage. With its help, viscoelasticity is maintained and lubrication properties are provided. Hyaluronate is a kind of filter for degradation products of cartilage tissue and protection of pain receptors located on the synovial membrane.

The prerequisite for the synthesis of injectable forms of hyaluronate for synovial fluid replacement is the hypothesis about the relationship between the reduction of synovial viscosity and pain intensity in patients with osteoporosis.

Hyaluronate is obtained by various methods: extraction, bacterial fermentation, synthesis of stabilized hyaluronic acid of non-animal origin. Parenteral administration of drugs to reduce the severity of symptoms not only provides better lubrication of the articular surfaces, but also serves as their protection from any biomechanical impact. Hyaluronate has a positive effect on processes occurring in tissues:

stimulation of the production of the main articular components - collagen, proteoglycans, endogenous hyaluronate, hyaloderin;
acceleration of chondrocyte metabolism;
inhibition of the expression and functional activity of enzymes that are involved in the destruction of joints;
regulation of apoptosis and prevention of the development of the inflammatory process;
inhibition of the inflammatory process that destroys the matrix.

Intra-articular injections of hyaluronate have an intense and long-lasting anti-inflammatory effect due to the suppression of white blood cell migration, leukocyte phagocytosis, lymphocyte proliferation, and prostaglandin production.

In a randomized, double-blind study, 40 patients with osteoarthritis of the knee were given 5 injections of hyaluronate solution. In patients, the number of active macrophages and lymphocytes in the synovial fluid significantly decreased in comparison with parenteral administration of placebo (isotonic sodium chloride solution).

What to do if effusion accumulates, how to treat it?

First of all, it should be taken into account that whatever the reason for the fact that water accumulates, recovery is not limited to just taking pills or just surgery. A comprehensive treatment is always carried out to achieve the most favorable result. At the moment, there are two ways to eliminate the problem - surgery and a conservative method. The conservative (non-surgical) method is treatment with tablets and dietary supplements, manual therapy, massages, physical therapy. Based on the doctor’s assessment of the degree of complexity and advanced stage of the disease, the most appropriate of these two methods is prescribed. Even if surgical intervention is proposed, it may be preceded by a conservative one aimed at relieving pain and stopping inflammation, in the presence of which surgical measures cannot be started. After surgery, massages, physical therapy and vitamin support are usually prescribed, which contribute to the development of the joint, the formation of general and local immunity and the establishment of metabolic processes in tissues. The intervention itself proceeds as follows:

1. A specially designed needle is inserted into the problematic diarthrosis. 2. Using a needle and syringe, the accumulated biomass is removed from the knee area. 3. After this, the medicinal substance is administered. This is done in order to avoid infection and the development of inflammation. Typically this procedure is performed without the use of anesthesia.

The conservative method is carried out using immunostimulating therapy, anti-inflammatory therapy, reflexology, physiotherapy, massage and manual therapy, and therapeutic exercises.
Immunostimulating therapy consists of taking a course of special drugs that strengthen the immune system, vitamin complexes, calcium and general strengthening medications. Anti-inflammatory therapy consists of a course of drugs depending on the causes of the disease and the use of local remedies - gels and ointments that prevent inflammation. Pharmacopuncture may also be prescribed if necessary. Reflexology, or acupuncture, is the effect of acupuncture on the foci of the disease, in which biologically active points of the body are stimulated. Reflexotherapy effectively improves blood circulation and metabolic processes, saturates tissues with oxygen, relieves spasms of blood vessels and muscles, and helps relieve inflammation. Physiotherapy is carried out using electromagnetic influence, hydrotherapy, heat and cold. People with fractures or bursitis need to ensure immobility - immobilization - of the affected joint. To do this, they are given a plaster cast. If synovial thickening accumulates due to injury, the patient is prescribed an antibiotic and the damaged area is treated with an antiseptic. These measures are taken to avoid the onset of a purulent or infectious disease. Chronic diseases that tend to recur cannot be cured completely, of course, but remission can be maintained through constant medication, diet and a set of therapeutic exercises. In addition, such a patient should regularly attend health courses in a sanatorium. When effusion collects in the cavity of the knee joint, this is a very alarming bell that cannot be ignored and left to chance. Therefore, self-medication is unacceptable.

And folk remedies can be used only after consultation with a doctor and only as additional supportive therapy, and not an independent course.

How to treat the accumulation of effusion in the knees with folk remedies?

Popular traditional medicine recipes for treatment include bay leaf oil, comfrey ointment and rye decoction.

Bay leaf oil

Rub the sore spot with this oil three times a day until it heals. In order to prepare bay oil at home, you need to take a couple of tablespoons of dried bay leaves and a glass of vegetable oil, mix and leave for a week.

Comfrey ointment

Rub the leg with this ointment twice a day, after which an elastic bandage is applied. To make the ointment, a glass of chopped comfrey grass is mixed with 200 grams of lard and left for five days.

Rye decoction

The decoction is prepared very simply: take half a glass of rye grains per liter of water and boil them for 20 minutes.
Cool the broth and pass through cheesecloth. Add half a kilogram of honey, 200 grams of vodka and 2 teaspoons of barberry to the cold rye broth. Mix the mixture thoroughly and place in a dark place for three weeks. Take 2 tablespoons on an empty stomach three times a day. Treatment of synovial deficiency
When there is little lubricating secretion in the knee, it is just as bad as having it in excess. In people of different ages, synovia is produced from the aqueous phase contained in the blood, proteins and hyaluronic acid, which provides it with the necessary viscosity. So, it resembles blood plasma. With the difference that there is no hyaluron in the plasma and the protein level is higher. The synovial mass is thick, transparent with a yellowish tint.

When there is not enough of it, bones and cartilage begin to rub against each other, which provokes their destruction and accelerates wear. This is accompanied by discomfort, crackling in diarthrosis, pain and decreased mobility. It is designed to envelop its cavity from the inside, nourish the cartilage, protect the surfaces of the bones from wear, and promote their mobility. If it is produced in insufficient quantities, this may be a consequence of:

disturbances in its production;
development of helminths in the body;
infections that dehydrate the body;
decreased immunity;
poor nutrition, lack of nutrients for tissues;
insufficient water consumption;
inhibition of hyaluronic acid production in older people;
excessively active physical activity, during which the volume of the synovium simply does not have time to recover.

If there is no fluid in the knee joint, what to do, what foods to introduce into the diet and how to restore its production with medication? The easiest way to restore sufficient production of lubricating mass in diarthrosis is to improve nutrition and saturate the menu with products that contain collagen. Such products include jelly, jellied meat, jellied meat, chicken broth, grapes, and potatoes. Medicinal recovery by taking chondroitin and glucosamine is also possible. If it is impossible to restore the production of lubricant internally for one reason or another, doctors resort to introducing an artificial replacement directly into the patient’s leg.
