摘要： A prosthetic femoral component (10) for an orthopaedic prosthesis has a canted patellar groove adapted for optimal patella/component interaction, with the component configured to have a medial or lateral cant depending upon the method of implantation. The femoral component defines a distal “component transverse plane,” which is a plane tangent to the distal-most points of the component condyles (12, 14). In a “mechanical” implantation, the component transverse plane is substantially normal to the mechanical femoral axis of the femur after the component has been implanted. Where the femoral component is configured to be “mechanically oriented” in this manner, the component has a medially canted patellar groove. On the other hand, an “anatomic” implantation is one in which, after the component has been implanted, the component transverse plane is substantially parallel to an “anatomic” transverse plane. The anatomic transverse plane is perpendicular to the anatomic axis of the femur from a sagittal view, and is inclusive of a line connecting the distal-most points of the natural femoral condyles before resection. Where the femoral component is configured to be “anatomically oriented” in this way, the component has a non-canted or slightly laterally canted patellar groove.

摘要翻译：用于整形外科假体的假体股骨部件（10）具有适于最佳髌骨/部件相互作用的倾斜髌骨凹槽，该部件被配置为具有取决于植入方法的内侧或侧向倾斜。股骨部件限定远端“部件横向平面”，其是与部件髁（12,14）的最远点相切的平面。在“机械”植入中，部件横向平面在部件植入之后基本上垂直于股骨的机械股骨轴线。在股骨部件以这种方式被配置为“机械地定向”的情况下，该部件具有中间倾斜的髌骨凹槽。另一方面，“解剖学”植入是其中在部件植入之后，部件横向平面基本上平行于“解剖”横向平面。解剖横向平面垂直于股骨的解剖轴线，从矢状视图，包括在切除前连接天然股骨髁的最远点的线。在股骨部件以这种方式构造为“解剖学定位”的情况下，该部件具有非倾斜或稍微侧向倾斜的髌骨凹槽。
