The OA Kneetrac knee brace is designed to alleviate pain in individuals suffering from moderate to severe osteoarthritis of the knee joint. It provides traction treatment, which increases the gap between two bone joints. Thus, it reduces body weight on the worn-out joint. The H-shaped frame design provides a stable structure. The frame is made of Duralumin, a metal that is light but strong. The surface of the frame is anodised using a special technique.
