Systems and methods for providing deeper knee flexion capabilities. In some instances, such systems and methods include a tibial component that has an asymmetrical articular plateau that includes a medial tibial condylar surface and a lateral tibial condylar surface. In some cases, at least one of the medial condylar surface and the lateral condylar surface includes a concave articulation surface having a lowest point that disposed from a posterior edge of the tibial component by between about 18% and less than about 35% of a total anteroposterior dimension of the tibial component. Other implementations are also discussed.
