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 peripheral rail extends along at least an anterior section of the perimeter of the tray's platform. The peripheral rail extends upwardly from an upper surface of the platform. A retaining rail extends upwardly from the upper surface of the platform and posteriorly away from the peripheral rail.
