Osteoarthritis of the knee

Osteoarthritis of the knee is a disease caused by joint inflammation. When the joint becomes inflamed, it will cause local endothelial damage and gradually lead to joint deformation. Most of the joint deformations occur in middle-aged and elderly people. It is also called knee rheumatism and old cold legs clinically. After the disease occurs, it needs to be slowly adjusted to eliminate the cold. Do not drink cold drinks in summer, do not use fans and air conditioners for a long time, keep warm and prevent catching cold.

Osteoarthritis of the knee

The knee joint supports the heavy body and can perform movements such as bending and straightening. It is a joint that often engages in strenuous exercise. The knee joint works in a harsh environment and is subjected to severe impact every time the foot touches the ground. The knee joint is also a frequently injured part of the body due to such intense work.

Therefore, the knee joints that are frequently exercised are most susceptible to diseases, such as: osteoarthritis, chronic rheumatoid arthritis, meniscus injury, ligament injury, etc. Among them, osteoarthritis of the knee and chronic rheumatoid arthritis are most easily caused by meniscus injury, so people call them the three major joint diseases of the knee.

There are many people suffering from knee pain in China, which is usually diagnosed as "osteoarthritis of the knee", "rheumatism of the knee joint", "old cold legs", etc. It is more common in middle-aged and elderly people, and has a great impact on people's quality of life. Most people think that knee pain is rheumatism, but when relevant examinations are done, it is found that the vast majority of people do not have true rheumatism. In fact, among patients with knee pain, more than 90% suffer from osteoarthritis, or "degenerative knee disease."

Osteoarthritis of the knee refers to the pain and inflammation caused by the wear and thinning of the 3-4mm thick articular cartilage covering the surface of the joint bones, and the direct friction between the bones on the inside. This results in a disease with symptoms such as pain, soreness, swelling and fluid accumulation. It is the second most common disease in orthopedics, second only to low back pain, and has a very high incidence rate. Osteoarthritis of the knee usually has a very slow onset and is a concentrated manifestation of multiple knee joint diseases.
