Osteoarthritis of the knee joint, it is a common and frequent clinical disease, also called age-related arthritis, degenerative arthritis, is actually not an inflammatory disease, but mainly degenerative changes, which is premature aging of the joint, and it threatens the normal life of about 1/3 of adults worldwide. Some patients have to have surgery to replace artificial knee or artificial hip joints because the joint disease is very serious, so how to slow down the aging of the joints? 1, first of all, the patient should understand a certain amount of relevant knowledge, to understand and cooperate with self-care. Usually should pay attention to the rest of the affected limbs, avoid overwork, excessive weight bearing, and should not sit or stand for a long time. Do not exercise too much and prevent acute and chronic injuries, the elderly should avoid strenuous exercise, to walk, tai chi and other gentle exercise. 2, appropriate muscle exercise Practice the muscle strength of the quadriceps in front of the thigh, which can reduce the burden on the knee joint. Functional exercise is very important, but the functional exercise should be carried out gradually, not too fast and excessive. Patients can perform active non-weight-bearing activities, such as muscle contraction and relaxation, joint extension and flexion, straight leg raising and other exercises to ensure that the joint can maintain a certain degree of mobility, prevent muscle atrophy, and achieve the purpose of preventing the development of the disease. 3, maintain the appropriate weight osteoarthritis in obese women than obese men in the incidence of higher. A study of a group of middle-aged women showed that the risk of osteoarthritis in both knees was 18 times higher in obese people than in ordinary women! 4, walking with a cane Some studies have shown that climbing, running sports, the role of the hip joint to bear the stress is 10 times the weight, while the usual walking hip stress is 3 to 5 times the weight. The use of a cane can significantly reduce the joint contact pressure, because the force arm of the cane is much larger than the force arm of the abductor muscle. And if the cane bears 15% of the weight, the pressure on the joint is reduced by 50%, while the joint pressure when walking with crutches is 65% of that when walking without crutches. 5, do not ignore the initial joint swelling pain tuberculosis, septic, rheumatoid, psoriatic, gouty and other joint abnormalities caused after the hospital should go to a specialist to stop the development of the disease, the development can appear joint deformity, joint instability, serious joint destruction can result. 6, early home treatment such as home physiotherapy, heat therapy, external use of Chinese and Western medicine cream, can reduce the symptoms, but can not change the bone lesions. When there is no swelling in the pain, you can take oral Daphne, Xilabao, etc. You can also take Chinese medicine such as Panax notoginseng tablets and Kidney Qi Pills, etc. 7.Intra-articular injection therapy Inhibit the release of inflammatory mediators and change the abnormal synovial fluid secretion in the joint by intra-articular injection of hyaluronic acid preparations, which can relieve pain and alleviate the pathological process of cartilage degeneration, and is effective in about 70% of patients. 8, appropriate exercise swimming, walking is also a good way to exercise. Usually, you can do some wall or crossbar standing kicking exercise, the method is taut thighs, parallel up, the purpose is to strengthen the quadriceps muscle strength.
