The knee joint is the intersection of the upper and lower leg bones, with a meniscus in the middle and a patella in the front. The patella is stretched by two muscles and suspended in front of the intersection of the leg bones, making it very easy to slide. In normal life, due to not being affected by external forces or intense exercise, the patella can move normally in a small range in the knee area. Due to the excessive pressure exerted on the knee by mountaineering, coupled with the intense exercise during mountaineering, it is easy for the patella to be pulled away from its original position, leading to knee joint diseases. Wearing knee pads can fix the patella in a relatively stable position to ensure that it is not easily injured. The above is about the mild braking effect of knee pads when the knee joint is not injured. After knee joint injury, using a knee pad with severe braking can reduce knee bending, maintain a straight line from thigh to calf, reduce knee joint bending, and protect the knee joint from worsening the condition.
