The knee is a very important body joint for athletes. The knee is the largest bearing joint of human body, and the average weight of people can be 35 kg. However, the more load-bearing, the easier the articular cartilage is to wear, and the faster the knee degeneration. Usually, the weight of standing and walking to the knee is about twice of the weight, running is four times, playing is as high as six times. Thinking that my knee is stimulated by more than 300 kg per week for no less than 100 times, I am quite worried about my knee.<br>
