    Abstract: According to one example, a tibial prosthesis that can include a tibial bearing component, tibial baseplate, an insert and a fastener. The tibial bearing component can have medial and lateral proximal articular surfaces and an opposing distal surface. The tibial bearing component can define at least one recess therein with the recess having an opening at a periphery of the tibial bearing component. The tibial baseplate can be coupled to the tibial bearing component on the proximal surface thereof and having a distal surface configured to be disposed on a resected proximal surface of a tibia. The insert can be configured to be disposed within the recess and can engage the tibial baseplate and the tibial bearing component. The fastener can be insertable into the tibial bearing component and can be configured to retain the insert to the tibial baseplate.

    Abstract: An orthopaedic knee prosthesis includes a tibial bearing component with surface features which operate to protect adjacent soft tissues of the natural knee throughout a wide range of flexion. More particularly, the tibial bearing component provides an anterior relief space disposed between the dished lateral and medial articular compartments, in which the relief space is convex as viewed from a sagittal perspective across the medial/lateral extent of the relief space.

    Abstract translation: 矫形膝关节假体包括具有表面特征的胫骨支承部件，其操作以在广泛的屈曲范围内保护天然膝盖的相邻软组织。 更具体地，胫骨支承部件提供了设置在碟形侧面和内侧关节间隔室之间的前部浮雕空间，其中，从矢状视角观察，当从浮雕空间凸出时，浮雕空间是凸出的，穿过浮雕空间的内侧/外侧范围。

    Abstract: A set of distal femoral knee prostheses which are designed to be more narrow in medial/lateral dimensions with increasing anterior/posterior size than existing prostheses to more closely correspond to the physical anatomy of female patients. The prostheses are designed to have a substantially trapezoidal shape or profile when viewed distally which features a more pronounced narrowing of the medial/lateral dimensions beginning at the posterior end of the prostheses and progressing anteriorly to the anterior end of the prostheses. Additionally, the prostheses each include a reduced profile patellar sulcus and reduced profile anterior condyles to more closely conform to the anatomy of a resected femur, and also include sulcus tracking optimized to conform to female anatomy.
