Knee free body is formed due to degenerative changes in the joint, where the cartilage degenerates, resulting in partial peeling of the cartilage layer and freeing it from the joint. Symptoms include joint pain, joint interlocking and so on.
1. Joint pain: If the free body is small, the patient is usually asymptomatic. If the free body is large, it may squeeze and damage the articular cartilage and meniscus when the joint is bent, thus causing joint pain, and some of the joints may be swollen, resulting in localized inflammatory reaction. If the pain is obvious when pressed, it is recommended to go to the hospital for examination and treatment as soon as possible.
2. Joint interlocking: the free body is stuck in the joint space, manifested as walking or strenuous exercise when the joint suddenly stuck, can not move, and accompanied by obvious pain. The knee joint can be unlocked by slowly moving it in place and normal activities can be resumed, and the pain will be significantly relieved. If you can’t unlock the joint by moving it in place, please consult a doctor and don’t move it too hard to avoid joint damage.
It is recommended to go to a regular hospital as soon as possible to get a clear diagnosis and treatment when the symptoms of knee joint free body appear.
