Osteoarthritis (OA) is a very common chronic joint disease characterized by degeneration, destruction and bone hyperplasia of articular cartilage. Our knees are covered with cartilage, and the cartilage is soft. This will avoid the “just-to-just” sputum and cushion the impact between the bones. However, such a long-lasting impact, even the best protection pads will wear out. And as the body ages, the ability to repair cartilage will become worse and worse. Finally, the cartilage will be worn less and less, the surface of the joint will be uneven, and the bones will appear on the edge, replacing the cartilage in the original joint, and then develop into osteoarthritis. Degenerative osteoarthritis and osteoporosis are common bone diseases in middle-aged and elderly people. The causes, age, obesity, excessive joint use, etc. are all predisposing factors. Experts said: “Clinically found that there are more female patients than males, which may be related to the reduction of female estrogen secretion after menopause.” It is understood that the population of over 60 years old in China has exceeded 100 million, of which about 5000 patients with osteoarthritis. Million. Studies have found that the prevalence of osteoarthritis increases with age, the prevalence of OA in people over 75 years old reaches 80%, and the number of people over 60 years old drops to 50%. The 40-year-old population only has 10-17%. Many elderly people think that their knee pain is due to calcium deficiency, and then blind calcium supplementation has not improved, but this is not the case, so if this problem really occurs, it must be taken seriously, not sloppy. The symptoms of osteoarthritis are generally knee pain, swelling, cartilage damage, morning stiffness, inconvenient walking, etc.; in the late stage of the disease, the joints will be deformed, the patient’s activities will be gradually restricted, and the joint function will be lost and the disability will result. If you are only a mild osteoarthritis patient, you can still do some moderate physical exercise, the purpose is to enhance the strength and endurance of the surrounding muscles, to help the stability of the joints, and to maintain the range of motion of the joints. For example: cycling, swimming and other sports, avoid climbing, jogging, jumping and other activities that are very stressful to the knee; patients who develop severely to the late stage can only perform surgical replacement of the joints in order to avoid losing joint function. However, the joint is also a relatively closed cavity structure, and surgical treatment is also faced with problems such as allogeneic rejection and sequelae. For the key points of osteoarthritis, the No. 1 osteoarthritis brace can better relieve pain and swelling and repair degraded or damaged cartilage. Not only prevents further deterioration of the disease, but also reverses the pathological process and reduces side effects. This can be said to be an effective way to eat painkillers and surgical treatment.
