Abstract

Abstract A knee brace designed to help stabilize the knee ligaments and provide support for the knee joint, comprises a tubular elastic sheath placed over the knee, a strap attached midway between its ends to the sheath which wraps around the sheath and crosses behind the knee cap in a crisscross manner to achieve the added support of the knee ligaments. The knee brace contains no supportive rigid components and does not impede normal flexability of the knee joint. An apertured disc is positioned on the sheath by the strap which applies pressure on it to relieve the pain associated with Osgood-Schlaughter disease.
