By analysing sections of distal femurs in the computer, and by making direct measurements, the posterior femoral condyles were shown to closely fit spherical surfaces. The center of the spheres were then used as reference points and used to define reference axes in a motion study. In flexing from 0 to 120 degrees the medial femoral condyle moved little, the lateral moved posteriorly by 17 mm, and there was an axial rotation of 20 degrees. The data were applied to implant and orthotic design and evaluation.
通过在计算机中分析股骨远端的切片，并进行直接测量，结果显示股骨后髁与球形表面紧密贴合。然后将球心用作参考点，并在运动研究中用于定义参考轴。在从0度弯曲到120度的过程中，股骨内侧髁移动很少，外侧髁向后移动了17毫米，并且存在20度的轴向旋转。这些数据被应用于植入物和矫形器的设计与评估。
