Many patients who come to the orthopedic department of Chinese medicine ask: Doctor, is knee pain a rheumatic disease? It is difficult to answer this question because it involves different medical concepts in Chinese medicine and Western medicine. What people usually call “rheumatism” is a Chinese medical name for a disease that is paralyzed and is caused by a combination of wind, cold, moisture and other foreign pathogens, which can be manifested as joint pain, coldness and sinking, and the symptoms can be aggravated by weather changes. In Western medicine, rheumatic diseases refer to a large group of diseases affecting joints and their surrounding tissues, including more than 300 diseases recognized by modern medicine, such as rheumatoid arthritis, ankylosing spondylitis, lupus erythematosus, dry syndrome, etc. The spectrum of diseases is different from that of Chinese medicine. In orthopedic clinics, many kinds of diseases become more pronounced when the weather changes, especially when it rains or is cold with joint pain. One of the most common diseases is osteoarthritis, which is also the one most easily mistaken for rheumatism by the general public. Osteoarthritis is a degenerative disease that occurs in the bone joints and is extremely common in the knee, hand joints, cervical spine and lumbar spine. Its clinical manifestations are: slow onset, limited location, aggravated by activity and relieved by rest; pain is aggravated by cold and cold, and relieved by warmth. The affected joints are mainly painful, occasionally accompanied by swelling of the soft tissues around the joints (or called synovitis). There is a frictional sound when the joint is moved, and joint deformity occurs in severe cases. In terms of treatment and health care, the main points are as follows: first, we should pay attention to rest to avoid re-injury; second, we can go to the hospital for systematic treatment, dialectical oral Chinese medicine soup, oral aminogrape sulfate and other cartilage-nourishing drugs; external application of Chinese ointment to activate blood circulation and remove blood stasis, as well as external washing of Chinese medicine; we can also intra-articular injection of nutrient-lubricating sodium glacial; pain relief drugs can be taken if the pain is obvious; if the symptoms of conservative treatment If the symptoms are not relieved by conservative treatment and the joint degeneration is serious, surgery can be considered. The following points should be noted in the prevention and care of the knee: pay attention to the warmth of the knee joint, apply heat and massage to the knee joint regularly every day; avoid overexertion of the knee joint, try not to do excessive squatting exercises of the knee joint, avoid climbing mountains and going up and down stairs as far as possible; reduce body weight if the body is too obese; swim, walk, bicycle, supine straight leg raise, resistance training, joint flexion and extension without weight bearing Activities.
