Synovial membrane is an essential part of the body to reduce friction between joints and tissues, and if it is damaged, it can lead to synovitis, a multifaceted disease that develops mainly in the knee joint. Synovitis can lead to joint effusion, joint enlargement, and pain, causing a lot of inconvenience to the patient’s life and work. Early prevention can effectively relieve the pain and inconvenience caused by synovitis.
Symptoms of synovitis
1. Knee hematoma
After an acute sprain or trauma to the knee joint, there will be joint hematoma, with extensive petechial hematoma at the sprain site. There is tension in the skin or swollen area, often with systemic symptoms such as fever caused by stasis of blood and more localized heat.
2. Synovial congestion, swelling, and restricted movement
When the knee joint is directly hit by violence, long-term weight-bearing chronic strain, indirect knee sprain, injury during surgery, incorrect habitual movements or even improper shoe wear can cause traumatic synovitis, manifested as congestion and swelling, normal synovial fluid is alkaline fluid, due to increased exudation after injury, the accumulation of acidic products in the joint, synovial fluid becomes acidic, prompting fibrin precipitation, prompting synovial membrane to gradually thicken, and there is Fibrous mechanization, causing adhesions, affecting the normal activities of the joint.
3. Heavy discomfort in both legs, difficulty in knee extension and flexion, pain is not obvious
Chronic strain or injury synovitis of the knee often causes this phenomenon, acute synovitis of the knee improperly handled leading to chronic formation caused by the performance of both legs heavy discomfort, knee extension and flexion difficulties, not active movement are not obvious obstacles, pain is not intense, local not red not hot.
Synovitis prevention methods
1, avoid long-term strenuous exercise
Long-term, excessive, strenuous exercise or activity is one of the basic causes of synovial degeneration. Especially for weight-bearing joints (such as knee joints, hip joints), excessive exercise increases the stress on the joint surface and increases wear. Long-term strenuous exercise can also make the bones and surrounding soft tissues overly stressed and strained, resulting in local soft tissue damage and uneven stress on the bone and iliac, resulting in osteophytes.
2.Appropriate physical exercise
Avoid long-term strenuous exercise, not inactivity, on the contrary, appropriate physical exercise is one of the good ways to prevent osteophytes. Because the nutrition of joint cartilage comes from the joint fluid, and the joint fluid can only enter the cartilage by “squeezing” to promote the metabolism of cartilage. Proper exercise, especially joint exercise, can increase the pressure in the joint cavity, which is conducive to the penetration of joint fluid into the cartilage and reduce the degenerative changes in the articular cartilage, thus reducing or preventing synovitis, especially the hyperplasia and degenerative changes in the articular cartilage.
3, timely treatment of joint injuries
Joint injuries include soft tissue injuries and bone injuries. Osteomalacia of the joint is often directly related to intra-articular fractures. Incomplete fracture repositioning causes uneven articular cartilage surfaces, resulting in traumatic arthritis. For patients with intra-articular fractures, if timely treatment and anatomical repositioning can be done, the occurrence of traumatic arthritis and joint osteophytes can be completely avoided.
4.Weight reduction
Excess weight is one of the most important causes of osteophytes of the spine and joints. Excess weight accelerates the wear and tear of joint cartilage, causing uneven pressure on the cartilage surface of the joint and causing synovial inflammation. Therefore, for people who are overweight, proper weight loss can prevent spinal and joint synovitis.
Synovitis treatment has tricks
1.Tui na therapy.
(1) pushing and kneading point press method: the patient lies on his back, the knee from top to bottom, repeatedly pushing and kneading along its tendons for 1 to 2 minutes.
(2) stretching and flexion method: patient position as above, muscle relaxation, the doctor first gently, small back and forth flexion and extension of the knee joint, and finally try to fully flex the knee joint, and then straighten the affected limb.
(3) Tendon scraping and splitting method: The patient lies on his back and uses one thumb to bend the knuckle above and below the patella, placing it on the inner side of the painful spot. The palm of the other hand is pressed on top of the flexed thumb, and the thumb is pushed outward with arm force for several scrapes.
(4) In case of joint effusion, use the whack, ring and beat method, alternately. Pound for the real fist, hit for the empty fist, hit the soft tissue around the patella and thigh extension, large and small leg flexion and extension 20-30 times each, ring for the real fist, double fist with arm force down the same place as the upper part, repeat 1 to 2 times. Pat not with fist but with the palm of the hand to pat N fossa, with wrist force pop pat.
2.Puncture therapy.
When there is more joint fluid and tension, joint puncture can be performed to completely draw out the fluid and blood, and inject sodium hyaluronate into the joint cavity, which is the main component of synovial fluid. Studies have shown that various pathological changes in arthritis are closely related to its reduction and altered physicochemical properties. Sodium hyaluronate injections have the following effects: covering the articular cartilage surface, which protects the articular cartilage and prevents or delays further degeneration. Protects the synovial membrane of the joint, removes pain-causing substances, and has a significant pain-reducing effect. Improves the contracture of joints and increases the mobility of joints. Improve the synovial fluid of degenerated joints.
3.Fixation and practice therapy.
In the early stage, bed rest should be taken, the affected limb should be elevated, and compression bandage can be used, and weight-bearing is prohibited. During the treatment period, you can exercise the quadriceps muscle stretching activities, and later should strengthen the knee flexion and extension exercise, which has a positive effect on eliminating joint effusion, preventing quadriceps muscle atrophy, preventing recurrent synovitis, and restoring the knee extension and flexion function.
