#$%^&*AU2010200901B220130606.pdf#####C :NRPanbl DCC CJVA2763690. DOC-3/10/2010 ABSTRACT Knee prostheses (100) featuring components that more faithfully replicate the structure and function of the human knee joint in order to provide, among other benefits: greater flexion of the knee in a more natural way by promoting or at least accommodating 5 internal tibial rotation in a controlled way, replication of the natural screw home mechanism, and controlled articulation of the tibia and femur respective to each other in a more natural way. In a preferred embodiment, such prostheses include an insert component (400) disposed between a femoral component (200) and a tibial component, the insert component (400) preferably featuring among other things a reversely contoured 10 posteriolateral bearing surface (444) that helps impart internal rotation to the tibia as the knee flexes. Other surfaces can also be specially shaped to achieve similar results, preferably using iterative automated techniques that allow testing and iterative design taking into account a manageable set of major forces acting on the knee during normal functioning, together with information that is known about natural knee joint kinetics and 15 kinematics.1/24 224 100 229 206 232 200 222 216 L 228 204 212 400 202 300 M 210 214 226 FIG. 1A
