For middle-aged and elderly people who have knee pain and go to the hospital for an X-ray, many doctors will say that they have a bone spur in the knee joint, so today we will talk about the treatment and prevention of bone spurs in the knee joint. Knee spurs, as the name implies, are bone spurs on the bones around the knee joint. In the early stage, the spurs are mainly found in the intercondylar ridge, which becomes pointed. If the spurs continue to develop, many spurs will grow around the knee joint in the form of prominent warts, and the patient’s cartilage will be worn to varying degrees; in the later stage, many spurs will also grow on the upper and lower edges of the patella, and the patient’s knee cartilage will be worn down and the joint space will become significantly narrower. The bone spurs stimulate the surrounding soft tissues and produce aseptic inflammation, which further causes pain. For early-stage knee spurs, no special treatment is needed. The main focus is on self-care, taking care not to overdo distance sports, such as climbing, long-distance running, etc., and losing weight appropriately. In the middle stage of osteoarthritis of the knee, the patient can take medication, such as medication to lubricate the cartilage of the joint, on the basis of self-care. Surgery can be performed to clean up the synovial membrane and remove the free body. For late stage knee spurs, the patient’s knee joint is almost full of bone spurs, the surrounding soft tissue is heavily proliferated, and the joint space is obviously narrowed, which is quite late stage of osteoarthritis, and the effect of any conservative treatment is limited. The best surgical option is to use a surface knee replacement to completely resolve the knee joint problem. This will completely clear the synovial membrane, remove the bone spurs around the knee joint, and replace the cartilage of the knee joint with artificial material. Knee surface replacement is now a relatively mature surgical procedure and is an effective treatment for end-stage bone joints, and patients can fully resume their normal lives after surgery.
