Osteoporosis may cause joint pain, and the mechanism of joint pain caused by osteoporosis is mainly as follows: 1. Pain may be caused by bone destruction caused by osteophytes. 3. Osteoporosis may accelerate joint degeneration, such as collapse of the joint or pathological fracture during the onset of osteoporosis, which may lead to joint deformation or abnormal friction. As the rate of joint degeneration accelerates, it can cause the patient to feel joint pain.
