This study uses metrical characteristics of the patella to derive population specific equations for sex determination in South Africa. Six measurements were taken from 120 normal and undamaged left patellae in a sample of known race, equally distributed by sex, obtained from the Raymond A Dart collection of human skeletons. These data were subjected to discriminant analysis. Maximum height and maximum breadth were selected in the stepwise analysis with an average accuracy of 83% in correct sex classification. Four functions were derived from the direct analysis with a range of average accuracy between 77% and 85%. While most individual variables showed high misclassification rates and may not be useful on their own, maximum height and maximum breadth have an average accuracy of 85 and 79%, respectively.
本研究利用髌骨的测量特征来推导南非特定人群的性别判定方程。从雷蒙德·A·达特人类骨骼收藏中获取了120块已知种族、按性别均匀分布的正常且未受损的左髌骨样本，对其进行了六项测量。这些数据进行了判别分析。在逐步分析中选择了最大高度和最大宽度，性别分类正确的平均准确率为83%。通过直接分析得出了四个函数，平均准确率在77%至85%之间。虽然大多数个体变量的错误分类率较高，单独使用可能没有用处，但最大高度和最大宽度的平均准确率分别为85%和79%。
