    • An extramedullary cut guide alignment assembly allows various adjustments to the cut guide without introducing bending stresses in the rest of the assembly. More particularly, the angular orientation of the cut guide with respect to the tibia may be freely changed during use, while maintaining the angular orientation of the proximal fixation arm of the alignment assembly with respect to the proximal tibial surface to which the arm is affixed. To achieve this decoupling of the angular orientations of the fixation arm and cut guide, the proximal fixation arm is pivotably mounted to the cut guide alignment assembly. Thus, the alignment assembly may be adjusted as necessary to achieve a desired angular orientation of the cut guide mounted thereto, while the pivotable junction between the alignment assembly and the proximal fixation arm automatically adjusts to accommodate the changing angular arrangement.
    • 髓外切割引导对准组件允许对切割引导件的各种调整,而不会在组件的其余部分中引入弯曲应力。 更具体地,切割引导件相对于胫骨的角度取向可以在使用期间自由地改变,同时保持对准组件的近侧固定臂相对于固定有臂的近端胫骨表面的角度定向。 为了实现固定臂和切割引导件的角度取向的这种去耦,近端固定臂可枢转地安装到切割引导对准组件。 因此,可以根据需要调整对准组件以实现安装在其上的切割导向件的所需角度定向,同时对准组件和近侧固定臂之间的可枢转接合部自动调节以适应变化的角度布置。
