Abstract: A fixed-bearing prosthesis includes a femoral component having a medial condyle surface and a lateral condyle surface. The knee prosthesis also includes a bearing having 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 secured to the bearing. The tibial tray has a platform with an elongated stem extending downwardly from a lower surface thereof. A posterior buttress extends along a posterior section of the perimeter of the tray's platform, and an anterior buttress extends along an anterior section of the perimeter of the tray's platform. Differently-sized tibial trays are interchangeable with differently-sized bearings.

Abstract: A modular knee prosthesis system includes a femoral component having a stem, a plurality of different sizes of sleeves mountable on the stem, and a plurality of different sizes of augments mountable on the femoral component. The system is modular, and provides the surgeon with the option of distally offsetting the joint line by selecting the size of sleeve that will provide the desired joint line. The different sizes of sleeves have different axial lengths but share a common geometry along a substantial part of their lengths so that the same bone cavity will accept multiple sizes of sleeves.

Abstract: A knee prosthesis system has a tibial component with frame with medial and lateral openings to receive the medial and lateral bearing components. The bearing components have distal surfaces that are exposed when assembled with the frame and pegs extending distally from the distal surfaces. The system optionally includes a tibial base plate with elongated curved receptacles to receive the pegs and allow the frame and bearing component assembly to rotate when mounted on the base plate. Different thicknesses of bearing components can be selectively locked onto the frame. Different sizes of tibial components have commonly sized, shaped and positioned elements so that multiple sizes of tibial components can be mounted on the same prepared tibial surface.

Abstract: A knee prosthesis system for total knee replacement procedures includes a plurality of distinctly-sized femoral components, a plurality of distinctly-sized fixed tibial components, a plurality of distinctly-sized mobile tibial components, a plurality of fixed inserts, and a plurality of mobile inserts. Each of the mobile inserts is sized and shaped such that each may be optimally matched to one of the femoral components and may be used with any one of the mobile tibial components. Each of the fixed inserts is sized and shaped such that each may be optimally matched to one of the femoral components and may be used with any one of the fixed tibial components.
