PROBLEM TO BE SOLVED: To provide a prosthesis for a knee which is related to an implantable prosthesis for orthopedic surgery, which can be generally implanted. SOLUTION: A fixed-bearing prosthesis includes a femoral component having a medial condyle surface and the lateral condyle surface. This prosthesis for the knee also includes a bearing which has a medial bearing surface configured to articulate with the medial condyle surface of the femoral component and a lateral bearing surface configured to articulate with the lateral condyle surface of the femoral component. A tibial tray is fixed to this bearing. The tibial tray has a platform and has a platform with an elongated stem extending downwardly from a lower surface thereof. A posterior buttress extends along a posterior section around the platform of the tray and an anterior buttress extends along an anterior section around the platform of the tray. The tibial trays of a different size are interchangeable with the bearings of a different size. COPYRIGHT: (C)2009,JPO&INPIT |
