Abstract
Abstract A sleeve adapted to be placed over the knee, said sleeve being configured to anatomically conform to the thigh, knee and upper calf. The sleeve comprises a resilient elastomeric foam sheath having a fabric covering, with the elastomeric foam being adapted to contact the leg. The sheath is formed from a front panel and a rear panel, with the rear panel being basically diamond-shaped, and having upper and lower apices adapted to be positioned in the center of the rear of the leg. The front panel has side edges angled inwardly from the top and bottom, and the rear panel is secured to the front panel along the side edges of the front panel. The sleeve can include an opening over the patella, which permits the patella to project into the opening.
