    Abstract: 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.

    Abstract: A prosthetic patellar implant has a posterior articulation surface and an anterior attachment surface. The anterior attachment surface has a medial attachment surface and a lateral attachment surface. The medial and lateral attachment surfaces can be planar and angled relative to one another, meeting at a common intersection medially offset from the sagittal centerline of the implant. The medial and lateral attachment surfaces can include convexities. The anterior attachment surface can have one or more pegs and/or recesses.

    Abstract: A mobile bearing knee prosthesis enables a surgeon to convert a mobile bearing insert having articular surfaces, supported by a tibial base plate or tray from a rotating and translating prosthesis to one that rotates only. This conversion is accomplished with a fastener or locking member that connects through an opening in the insert to the tibial base plate. This prosthesis can be used as part of a total knee surgery when the surgeon chooses to use a prosthesis that incorporates a movable articular surface. In one embodiment, a projecting portion extends proximally from the insert and cooperates with a cam on the femoral component. The projecting portion can be a post extending up from the proximal surface of the insert and the femoral component includes an intercondylar surface that may contact the post to constrain the relative motion between the femoral component and the insert. In another embodiment, the insert is a two part assembly that includes a larger member with a central opening and a smaller member that fits the opening.

    Abstract translation: 移动轴承膝关节假体使得外科医生能够将具有由胫骨基板或托盘支撑的关节表面的移动轴承插入件从旋转和平移假体转换成仅旋转的假体。 这种转换是通过将插入物中的开口连接到胫骨基板上的紧固件或锁定构件实现的。 当外科医生选择使用包含可动关节表面的假体时，该假体可用作全膝关节手术的一部分。 在一个实施例中，突出部分从插入件向近侧延伸并与股骨部件上的凸轮配合。 突出部分可以是从插入件的近侧表面向上延伸的柱，并且股骨部件包括可以接触柱的髁间表面，以限制股骨部件和插入物之间的相对运动。 在另一个实施例中，插入件是两部分组件，其包括具有中心开口的较大构件和适合开口的较小构件。
