Knee wear specifically refers to the degeneration of the knee joint, where degeneration and loss of knee cartilage occurs. Since the damage to the articular cartilage is irreversible, the wear and tear of the knee is also irreversible. However, when knee wear occurs, effective interventions can be made to slow down the rate of joint degeneration and alleviate the chronic pain in the knee due to wear and tear. Glucosamine sulfate capsules can be used to nourish the articular cartilage and improve the metabolism of the chondrocytes to relieve the pain. Sodium vitrate can also be injected locally to lubricate the joints, resulting in less friction between the joints, which in turn results in the rate of wear and tear of the joints being greatly reduced. In addition, local physical therapy and hot compresses can also be used to improve blood circulation and relieve the symptoms of knee pain.
