Claim:
1. A system for knee arthroplasty comprising: a plurality of tibial bearing components including at least a first tibial bearing component from a first tibial bearing component class and a second tibial bearing component from a second tibial bearing component class that differs from the first tibial bearing component class, the first tibial bearing component and the second tibial bearing component including: an articular surface including medial and lateral dished articular compartments sized and shaped for articulation with a medial femoral condyle and lateral femoral condyle, respectively; a distal surface opposing the articular surface, wherein the distal surface of the first tibial bearing component is substantially similar to the distal surface of the second tibial bearing component such that both the first tibial bearing component and the second tibial bearing component are mountable to a common tibial tray; and a sagittal radius extending along the articular surface in an anterior-posterior direction and the sagittal radius having a radius center, wherein the sagittal radius and the radius center of the first tibial bearing component differs with respect to the sagittal radius and the radius center of the second tibial bearing component.
