Prostheses of the hip and the knee joint, of which both components are anchored into the bone with prestressing tendons (5) and by interposition of a joint. The anchorage system of the prostheses for the femoral part of the hip joint prosthesis and for both parts of the knee joint prosthesis consists of: (a) the sockets (3, 6) for the spheric end of the prestressing tendons on both components of the prostheses for the neutralization of tension forces, (b) the prestressing tendons, (c) the mechanism for bone protection, anchorage and fixing of the prestressing. The acetabulum part of the hip joint prosthesis is anchored into the bone of the pelvis with prestressing tendons. |
