The benefits and hazards of wearing knee pads are as follows: First, the benefits of wearing knee pads: mainly to protect the knee joint. For patients with knee joint injuries or serious lesions, using knee pads can enhance the stability of the joint and avoid aggravation of joint pain symptoms. Secondly, the danger of wearing knee pads: wearing knee pads for a long time will cause the muscle strength around the knee joint to weaken significantly, and the muscles will have atrophy, which is not conducive to the stability of the knee joint. Therefore, knee pads should only be worn for a short period of time, not for a long time. The knee pads should be removed for more than four weeks, otherwise the stability of the knee joint decreases, so there are both benefits and hazards to wearing knee pads, which should be balanced.
