Abstract
Abstract A knee strap for treating chondromalacia patella and similar disorders includes an elongated soft, flexible strap member which is long enough to encircle a person's leg just below the patella. The ends of the strap are flat and overlap each other behind the person's knee with Velcro holding the ends together. The center portion of the strap includes a rubber, tubular member which presses against the patella tendon to force the patella into proper alignment thereby reducing pressure and trauma on the underside thereof.
