US Patent 7438725 Knee cosmesis

A cosmesis includes a thigh component and a shin component that fit over a prosthetic knee joint. The thigh component and shin component are pivotally joined along an axis of rotation coinciding with that of the prosthetic knee joint. The thigh component and shin component can include internal contours molded into their inside walls to seat the prosthetic knee joint securely therein. The knee ball region of the thigh component can be made relatively thicker to provide a protective cushion and allow the patient to kneel. Additionally, a floating knee cap can be fit over the knee ball area. The upper end of the thigh component can be made of sufficiently thin material to permit rolling onto itself.
