摘要：
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.
