    • Knee prostheses 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 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 disposed between a femoral component and a tibial component, the insert component preferably featuring among other things a reversely contoured posterolateral bearing surface 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 kinematics.
    • 膝部假体具有更可靠地复制人类膝关节结构和功能的组件,以便提供以下优点:通过以可控方式促进或至少容纳内部胫骨旋转以更自然的方式更大地屈曲膝盖, 复制天然螺丝机构,并以较为自然的方式将胫骨和股骨相互联系起来。 在优选实施例中,这样的假体包括设置在股骨部件和胫骨部件之间的插入部件,插入部件优选地特征在于具有反向轮廓的后外侧支承表面,当膝盖弯曲时,该支承表面有助于使内部旋转到胫骨。 其他表面也可以被特殊地形成以获得类似的结果,优选使用迭代自动化技术,其允许测试和迭代设计考虑到在正常功能期间作用在膝盖上的可控制的一组主要力量,以及关于天然膝关节的已知信息 动力学和运动学。
