What Are the Common Causes of Swelling Above the Knee?

Synovitis is a common clinical disease, and the main disease is knee joint effusion. The knee joint is composed of the inner femoral, lateral condyle, and tibial internal, lateral condyle, and sacrum. It is the joint with the largest and most complex structure of the human body, and also has more opportunities for injury, so there are more opportunities for injury and infection. Synovitis of the knee joint is mainly caused by a sprain of the knee joint and various intra-articular injuries. Such as meniscus injury, synovial injury, cruciate ligament or collateral ligament injury, intra-articular injury and dislocation, knee osteoarthritis secondary to chronic knee synovitis and joint free body. Another cause is infection. Synovial tuberculosis is common. Generally, synovial blood vessels are abundant, blood circulation is good, and resistance to bacteria is strong. However, in the case of tuberculosis infection, the disease progresses slowly. Symptoms are good and bad, which is one of the chronic synovitis of the knee.

Synovitis of the knee joint is one of the common orthopedic diseases in the clinic. Because the knee joint is an important anatomical feature of the human body and the synovial membrane of the knee joint, the disease has the characteristics of greater pain and easy recurrence. In the past, methods such as joint cavity drainage decompression and drug washing were mostly used (mainly drugs are mainly anti-inflammatory and analgesics such as hormones and local anesthetics), but often the results are not satisfactory. The reason may be due to this method and such drugs The inflammation can only be eliminated temporarily, and the purpose of temporary pain relief can be achieved, but the damaged joint synovium cannot be repaired fundamentally. Once the joint is overloaded, it is easy to appear repeatedly.

1. Puncture therapy When there is a lot of joint effusion and tension, joint puncture can be performed to completely drain the effusion and blood, and

Synovitis is a common orthopedic disease. Once you have synovitis, it is very painful for patients. Synovitis in patients is often caused by a lack of exercise or inappropriate exercise. Therefore, homecare is important in daily life.

Long-term strenuous exercise should be avoided. Prolonged, excessive, strenuous exercise or activity is one of the basic reasons for inducing synovial degeneration. Especially for heavy-duty joints (such as knee and hip joints), excessive movement will increase the force on the joint surface and increase the wear. Long-term strenuous exercise can also cause excessive stress and tension on the bones and surrounding soft tissues, causing local soft tissue damage and uneven force on the epiphysis, leading to bone hyperplasia.

Proper physical exercise to avoid long-term vigorous exercise is not inactivity. On the contrary, proper physical exercise is one of the good ways to prevent bone hyperplasia. Because the nutrition of articular cartilage comes from synovial fluid, and synovial fluid can only enter cartilage by "squeezing", which promotes cartilage metabolism. Appropriate exercise, especially the movement of joints, can increase the pressure in the joint cavity, facilitate the penetration of joint fluid into cartilage, and reduce the degenerative changes of articular cartilage, thereby reducing or preventing synovitis, especially the proliferation and degeneration of articular cartilage Sexual change.

Timely treatment of joint injuries Joint injuries include soft tissue injuries and bone injuries. Bone hyperplasia of joints is often directly related to intra-articular fractures. Due to incomplete reduction of the fracture, the articular cartilage surface is uneven, which results in traumatic arthritis. For patients with intra-articular fractures, if they can be treated in time and anatomical reduction can be achieved, the occurrence of traumatic arthritis and joint bone hyperplasia can be avoided.

Reducing weight Overweight is one of the important reasons that induce bone hyperplasia of the spine and joints. Excessive weight will accelerate the wear of articular cartilage, make the pressure on the articular cartilage surface uneven, and cause synovial inflammation. Therefore, for people who are overweight, proper weight loss can prevent spinal and joint synovitis. ^[5]
