The knee joint is the major joint of the human body, and it is responsible for almost all activities in daily life, standing and walking, climbing, squatting, running and jumping. However, the human body has a strong self-repair ability, especially when young, often after some accidental injury rest after a period of time, but with the increase in age, the body’s self-repair ability gradually weakened, in the same encounter injury, the symptoms last longer and longer, the degree of relief is less and less than before. How to protect their legs and prevent premature aging of the knee joint, which also needs to start from childhood, from the daily habits of life: 1, the early years of attention to the presence of internal and external knee deformity, also known as rotundity or X-leg, due to weight bearing, the knee joint in the case of abnormal weight bearing, the knee joint inside and outside the force is not uniform, it is easy to lead to wear and tear on the side of the knee joint too much weight increased This can lead to the occurrence of osteoarthritis, and if there is a similar performance, you need to seek early medical evaluation to correct it, do not wait until symptoms appear before you think of seeing a doctor. 2, when young to participate in more strenuous sports activities should pay attention to protect themselves, adequate preparation before the activity, if necessary, wear protective gear, appropriate protective action is very important, in the clinical often see in soccer or basketball activities in patients with meniscal injury, after arthroscopic cleaning, meniscal molding surgery, after a number of years of early osteoarthritis performance, this is because the meniscus This is because the function of the knee joint cushioning protection has been weakened, so that the intra-articular environment changes. 3, people in middle age pay attention to exercise, avoid trauma. The surface of the knee joint has a layer of cartilage, and osteoarthritis occurs due to cartilage damage and degeneration, the surface of the cartilage is not vascular, its nutrition relies on the gradual infiltration of joint fluid, so proper movement of the joint can allow the joint cartilage to obtain adequate lubrication and nutrition, walking, brisk walking, cycling, swimming are better activities, and climbing up the stairs and squatting on the knee joint burden and damage are relatively large, not recommended. It is not recommended. 4, old age, pay attention to maintenance, the body organs are going downhill, the body’s coordination ability is weakened, the body’s self-repair ability gradually reduced, so increase protection, pay attention to the cold to keep warm, prevent falls and sprains, a balanced diet, appropriate to give some substances to promote the body repair such as glucosamine, can make the pace of aging become slower.
