Silicone Pad for Knee Support is ergonomically designed for shock absorption and stability enhancement. There are many ligaments to provide stability and prevent excessive motion. Circular silicone insert leaves the patella free from pressure and provides local relief. Surrounding profile ring ensures firm control of the patella and reduces medical lateral displacement. Does not restrict muscle movement. Moving the knee joint provides massaging effect to the upper recessed and the infra patellar fat pad.
