在全膝关节置换术中，用于实现股骨部件正确旋转对线的标志在外翻膝关节的远端结构中可能无法区分或不可靠。5名观察员确定了30具尸体股骨的前后轴、后髁轴和经上髁轴，以确定在手术环境中使用每种轴的可靠性。此外，对每个股骨的远端进行X线摄影，构建轴，测量角度，并与观察者进行的目视测量进行比较。垂直于前后轴画的线始终近似于相对于后髁表面的4度外旋。经上髁轴更难定义，也不准确。放射学检查结果与目视检查结果相似，但前者的标准差小于后者。前后轴似乎是外翻膝关节股骨部件旋转对线的可靠标志。
The landmarks used to achieve correct rotational alignment of the femoral component in total knee arthroplasty may be indistinguishable or unreliable in the distal architecture of a valgus knee. Five observers identified the anteroposterior axis, the posterior condylar axis, and the transepicondylar axis in thirty cadaveric femora to determine the reliability of the use of each axis in the operative setting. In addition, radiographs were made of the distal aspect of each femur, the axes were constructed, and the angles were measured and compared with the visual measurements made by the observers. A line drawn perpendicular to the anteroposterior axis consistently approximated 4 degrees of external rotation relative to the posterior condylar surfaces. The transepicondylar axis was more difficult to define and was not as accurate. The radiographic results were similar to the visual results, but the standard deviations for the former were less than those for the latter. The anteroposterior axis appears to be a reliable landmark for rotational alignment of the femoral component in a valgus knee.
