Turning the ankle will make a ringing sound, commonly due to the following reasons: 1. For elderly patients, most cases are degenerative osteoarthritis of the ankle joint, the patient will have extensive wear and tear of the articular cartilage and roughness of the joint surface, which will induce friction when turning the ankle joint and produce a joint ringing sound, accompanied by joint pain and limited joint movement, and the symptoms are more obvious when walking under weight. 2. In young patients, most of them have sports injuries. Acute injury to the articular cartilage will lead to roughness of the joint surface, and turning the ankle joint will also cause intra-articular rattling. In addition, there may be a relationship with the excessive tension of the muscles and tendons around the joint after the injury. Early diagnosis and early treatment can lead to relief of clinical symptoms. If it is a sports injury, it can even be completely cured.
