The role of knee pads has three points: One is braking, the other is heat preservation, and the third is health care.

     There is not much to say about heat preservation and health care. The knee is very susceptible to cold, and many knee joint diseases are related to cold knees. Therefore, many elderly people with poor legs and feet choose to wear knee support. But they are all medical equipment, which is very different from the sports safety products mentioned today. The main function of sports knee pads is to brake.

     The knee joint is where the upper and lower leg bones meet. There is a meniscus in the middle, and there is a patella in the front. The patella is stretched by two muscles, suspended before the junction of the leg bones, which is very easy to slide.

       In normal life, because it is not affected by external forces, and there is no strenuous exercise, the patella can move normally in a small range at the knee. Because exercise puts too much pressure on the knee, strenuous exercise can easily cause the patella to be retracted away from the original position, which can lead to diseases of the knee joint.

        Of course, if the knee joint has been injured, it is useless to wear sports knee pads. Elastic knee support are a front action, which can ensure that your knee joints are not injured as much as possible.

      After the knee joint is injured, you should seek medical attention immediately, use a knee pad with a medically heavily braked knee to reduce the bending of the knee, and maintain a straight line from the thigh to the calf. Reduce the bending of the knee joint to protect the knee joint from aggravating the condition.
