Knee pads are useful for meniscus injuries. They have 3 main functions: 1) to keep the knee warm. If the meniscus is severely damaged, there are symptoms such as pain and stiffness, which can be relieved by physical therapy such as herbal fumigation and herbal compresses. 2. Not only does it prevent the inflammation caused by meniscus damage from increasing further, it also allows the blood circulation in the knee joint to function normally, so that the knee joint does not become ischemic and necrotic.
