Bone and joint ringing may be caused by physiological factors, such as degenerative changes in the elderly, or it may be caused by diseases, such as meniscus injuries, muscle strain and so on. 1. Physiological factors: with age, degenerative changes occur in the bones and muscle tissues, and the ligamentous tissues around the joints also relax, resulting in increased mobility of the joints, which will cause bone ringing during exercise. 2. Meniscus injury: If the meniscus injury causes meniscus tear, during exercise, the meniscus will flip and shift, which will easily make the meniscus stuck between the femur and tibia, thus causing friction between the bones and lead to bone ringing. 3. Muscle strain: If the human body is in a state of fatigue for a long time, it is easy to cause muscle ligament damage. Muscle injury will easily cause localized muscle stiffness, which may also lead to bone ringing when massaging or rotating. If the patient has the situation of bone ringing, it is recommended that the patient go to the hospital in time to improve the bone local X-ray, CT, bone density and other examinations, to clarify the cause of the disease, and follow the doctor’s instructions for treatment.
