    摘要： 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.

    摘要： Systems and methods for implant optimization using intra-operative scanning are set forth. According to one embodiment, a method comprising intraoperatively scanning a joint surface, processing the scan and creating a three-dimensional computer model, performing simulations with the three-dimensional computer model, determining an optimal implant attribute from analysis of the simulations, selecting an optimal implant, determining an ideal positioning and orientation of the selected implant relative to scanned anatomical features, rapidly creating a patient-matched guide to facilitate bone surface preparation in order to achieve ideal positioning and orientation of the selected implant, preparing the surface using the patient matched guide, and implanting the optimal implant is set forth.
