In acute injury, someone can hear the noise in the joint by himself. It is often accompanied by synovial injury on the inner wall of joint capsule, which causes intra-articular bleeding and exudation. After the injury, the joint gradually swelled and the pain continued. After rest and general treatment of swelling and pain relief, the symptoms are relieved, but the joint space is still painful, especially when the joint flexes to a certain position. Walking, especially going up and down stairs, makes me feel weak in my lower limbs, and I often hit my legs and feel weak, which affects my work and life. After a long time, the thigh muscles atrophy and the circumference becomes thinner. When some patients walk, they suddenly feel abnormal pain in their knees, unable to move or even fall. Endure the pain, move the calf, and you can resume walking. This symptom is called joint atresia, which is caused by the injured meniscus blocking the joint. Some patients will feel bouncing in their knees and hear a click.

A few special types of meniscus injuries can be repaired, and most of them are removed. By removing the damaged meniscus, the symptoms of the knee joint can be eliminated or significantly alleviated. As time goes on, a meniscus structure will grow in situ. Although it is worse than the original normal structure, it also has most functions.

Meniscus injury can be treated in China, and arthroscopic surgery has a good effect.
