Thirty-six cadaver knees were examined by various morphometrical methods in order to obtain mathematical and graphical data concerning the geometry of the lower end of the femora. It was found that the paramedian sagittal curves represented magnifications of a certain curvature pattern specific to the medial and the lateral femoral condyle. These curves could be expressed mathematically for each condyle. Furthermore, we found dimensional as well as geometrical intervariations between the different size groups in the knee sample. This could serve as an argument for preferring a different design for medial and lateral condyle components in knee prostheses.
为了获取有关股骨下端几何形状的数学和图形数据,采用各种形态测量方法对36个尸体膝关节进行了检查。结果发现,旁矢状曲线代表了特定于内侧和外侧股骨髁的某种曲率模式的放大。这些曲线可以分别用数学方法表示每个髁。此外,我们发现膝关节样本中不同尺寸组之间存在尺寸以及几何形状的相互变化。这可以作为在膝关节假体中对内、外侧髁组件采用不同设计的一个论据。
