#$%^&*AU2008229657B220141204.pdf#####- 26 ABSTRACT OF THE DISCLOSURE 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 5 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 10 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. 26/09/08,va 17538 speci,261/5 12 42 321 44 54 4 64 70 2 20 Fig. I
