It is a kind of aseptic inflammation, which is caused by sprain of knee joint and various intra-articular injuries. Abnormal function of synovium will lead to abnormal production and absorption of joint fluid, and hydrops will be produced in knee joint. The morphological changes of synovium can also invade the cartilage of knee joint, which will lead to osteoarthritis of knee joint if it is not treated in time, and there is a great disability crisis.

The cause of disease

1. In young people, it is mostly caused by acute trauma and chronic injury. Acute trauma includes: knee sprain, meniscus injury, collateral ligament or cruciate ligament injury, intra-articular effusion or sometimes hematocele, which is manifested as acute traumatic synovitis of knee joint.

2. Synovitis in the elderly is mainly mechanical and biochemical stimulation caused by cartilage degeneration and hyperosteogeny, followed by synovial edema, exudation and effusion.

3. Sometimes it can also be caused by simple synovial injury or long-term chronic knee joint strain, which can gradually cause knee joint swelling and dysfunction, and then form chronic knee synovitis.

4. Infection, in which synovial tuberculosis infection is more common. Generally speaking, synovial blood vessels are rich, blood circulation is good, and anti-bacterial ability is strong. However, in the case of tuberculosis infection, the disease progresses slowly, and its symptoms are sometimes good and sometimes bad.

clinical picture

There is no age limit for synovitis of knee joint, but it can occur at any age. For young people, they usually do a lot of exercise, so after the knee joint is hit, twisted and overtired during exercise, it is easy to have swelling, pain, difficulty in moving, limping, local skin temperature is high, skin swelling and tension, or blood is punctured from the joint.

cheque

1. The knees and eyes on both sides of the patellar ligament are bulging and full, soft to the touch, and even cystic. If the joint effusion exceeds 50 ml, the floating patella test is positive.

2. Most of the liquid extracted by joint puncture is yellow, transparent or pink with blood, and the bacterial culture is negative.

3.x-ray examination shows that the synovitis bone is normal, or there are degenerative changes, or there are loose bodies in the joint and bone spurs at the edge of the joint.

diagnose

The examination showed that the knee joint was limited in flexion and extension, squatting was difficult with pain, there were localized tenderness points around the joint, and the floating patella test was positive. Chronic injury of synovium may have no obvious history of trauma, mainly manifested as weakness of knee joint, limited activity, persistent swelling and fear of squatting. The increase and decrease of activity after rest will get worse. Those who have been ill for a long time can feel the hypertrophy of the knee joint capsule. For patients with excessive or repeated effusion in the knee joint, joint effusion examination can be done, which can reflect the nature and severity of synovitis. Therefore, joint puncture and synovial fluid examination have important reference value for the diagnosis and differential diagnosis of knee synovitis.

treat cordially

1. Timely detection and treatment.

2. Western medicine treatment of knee synovitis mainly includes oral drugs and joint cavity.

Injection of drugs, irrigation, surgery, etc.

3. Chinese medicine external application therapy, massage therapy, etc.

prevent

1. Control your diet structure to avoid excessive intake of acidic substances and aggravate your acidic constitution. The acid-base balance of diet is very important for the treatment of synovitis and the prevention and treatment of complications. In terms of diet, we should eat more foods rich in animal organic active alkali, eat less meat and eat more vegetables.

2. Regular outdoor exercise and sweating can help to eliminate excess acidic substances in the body, thus preventing synovitis. But avoid overwork and keep warm. Pay attention to adjust your clothes, protect your knee joints that are prone to synovitis, don't crave air conditioning, and pay more attention to exercise at ordinary times to better prevent synovitis.

Keep a good mood and don't have too much psychological pressure. Excessive pressure will lead to the deposition of acidic substances. Proper adjustment of mood and stress can maintain weak alkaline constitution and prevent synovitis.
