Abstract
An orthosis is provided which is mountable on a knee having a femoral head and patella. The orthosis has upper and lower arms positionable about the knee and a hinge assembly positioned between the upper and lower arms at the knee to one side of the patella. A compression member is positioned at the femoral head adjacent to the patella on the opposite side of the patella from the hinge assembly. The compression member includes a tracking guide engaging the knee and a compression place in overlying engagement with the tracking guide. A tension strap is connected to the hinge assembly at an offset connection point by means of a tension strap mount. The tension strap applies a tension force to the compression member which increases when the upper and lower arms rotatably transition from the flexion position to the extension position and decreases when the upper and lower arms rotatably transition from the extension position to the flexion position.
