    • A device and method for resecting a distal portion of a femur comprises a distal cutting guide [98], a valgus guide [102], and a variable collet [10]. The distal cutting guide [98] is configured to overlie an anterior portion of the femur and comprises a slot for guiding a cutting tool across a distal portion of the femur. The valgus guide [102] is configured to connect to the distal cutting guide [98]. The valgus guide [102] is configured to align the slot of the distal cutting guide[98] at the proper varus/ valgus angle. The variable collet [10] is configured to attach to an intramedullary rod and the valgus guide [102]. The variable collet [10] comprises a port [30] for receiving the intramedullary rod. The port [30] is angularly adjustable with respect to the valgus guide [102] such that adjusting the port [30] adjusts the varus/ valgus angle of the distal cutting guide [98].
    • 用于切除股骨的远侧部分的装置和方法包括远侧切割引导件98,外翻引导件102和可变夹头10。 远侧切割引导器[98]构造成覆盖股骨的前部,并且包括用于引导切割工具越过股骨的远侧部分的狭槽。 外翻引导件[102]被配置为连接到远侧切割引导件[98]。 外翻引导件[102]被构造成以适当的内翻/外翻角对齐远侧切割引导件[98]的狭槽。 可变夹头[10]被配置为连接到髓内杆和外翻导向件[102]。 可变夹头[10]包括用于接收髓内棒的端口[30]。 端口[30]相对于外翻引导件[102]是可角度调节的,从而调节端口[30]调节远侧切割引导件[98]的内翻角/外翻角。
