With the family planning policy taking effect, China is moving into an aging society, and it is good that the state has liberalized birth control, and now Chinese people’s child-loving nature has immediately rebounded, so no one should mind the poor air and blame whoever it is. Everyone contributes to the haze and everyone enjoys the intrusion of the haze. Rambling, the book returns to the main story. The aging society, in the eyes of orthopedic surgeons that is to see the elderly leg pain arm pain, every day the clinic bustling, are the elderly seeking medical treatment, poor hard life, hard work nursing children to start a family, now fell a general discomfort, the results of the doctor even a companion can not find a person, the late scene is miserable sigh ah. These patients complaining of leg pain, it is clear at a glance, are degenerative knee osteoarthritis, or called arthritis, synovitis, osteophytes or long bone spurs, in fact, are the same thing, because the joint wear too much, the cartilage disappeared bone exposed in the joint fluid, so the pain is unbearable, hobbled. When you have arthritis, the first thing you should do is to take medicine, and if you can’t, you should put lubricant into the joint, and then you should have surgery. The so-called artificial joints, is to eliminate a layer of your broken joints, and then replaced with a metal, sounds good, however, the first is very expensive, the average person can not afford to replace, no health insurance can not stand, the second, this joint replacement once the failure to fuse the knee, is to get into the dead, legs into a straight stick, once so, it is better not to do. In fact, many older people do not know that in addition to joint replacement, most patients have another option, which is high tibial osteotomy. The name sounds both scary and difficult to understand. What is said here must be told from the beginning, that is, when a person stands straight, the leg should generally be a straight line, so that the power transmission is evenly distributed on both sides of the knee, which is the ideal state. However, Asians, especially East Asians, such as Korean, Japanese and Chinese, have the characteristic of inward knee, which is a racial characteristic and cannot be changed, so that when a person stands up the power transmission is on the inner side of the knee, so that in the long run, the inner side of the knee wears out, and this is arthritis, which has been talked about earlier. In such a case, there is no need to replace the joint at all, because by doing a minor surgery, that is, the force line of the bone is corrected, you can achieve satisfactory results, because the bone is broken right, the knee is evenly stressed, or intentionally let the outer side of the force a little more, the knee joint will fundamentally solve the cause of pain, the effect is very good, one week after the operation can feel the effect of the ground. Even if the effect diminishes later, it does not affect the eventual artificial joint replacement.
