1, try to avoid body obesity, to prevent aggravating the burden on the knee joints, once the body is overweight, we should actively lose weight, weight control. 2, pay attention to walking and labor posture, do not twist the body to walk and work. Avoid squatting for a long time, because when squatting, the weight of the knee joint is 3 to 6 times their own body weight, squatting at work (such as car mechanics, etc.) is best to change to a low sitting position (sitting on a small stool), sitting and standing for a long time, but also to change the posture often, to prevent the knee joints from being fixed in a position and exerting too much force. 3.Don’t wear high-heeled shoes when you walk long distances, wear soft-soled shoes with thick and flexible soles to reduce the impact on the knee joints.
