If a patient has ankle joint ringing, the causes include degenerative osteoarthritis, cartilage damage, strain and cold, etc., as follows: a. Degenerative osteoarthritis: degenerative osteoarthritis in the ankle joint area can easily cause internal ringing with pain when the ankle joint flexes and extends. Cartilage damage: damage to the cartilage inside the ankle joint can also cause the ankle joint to ring. Third, strain and cold: If the ligaments and joint capsule around the ankle joint are strained or cold, it will easily lead to spasm and contraction of the ligaments and joint capsule, resulting in abnormal friction when the ankle joint moves, which will also lead to ankle joint ringing. After the ankle joint ringing occurs, the patient must consult a doctor to see what causes it, and treat the cause to promote the recovery of the ankle joint ringing, especially if there is degenerative osteoarthritis or cartilage damage in the ankle, you must actively consult a doctor to avoid the later impact on the ankle joint flexion and extension, weight bearing activities.
