OBJECTIVES
To determine the difference in shape of the distal femur, viewed axially in two dimensions, between eburnated and non-eburnated femora.
METHODS
A comparison of 52 non-eburnated and 16 eburnated femora drawn from a large archeological skeletal population. Eburnation was taken to indicate late stage osteoarthritis. Shape variability, based on landmarks, was quantified using a principal components analysis after a Procrustes alignment.
RESULTS
A statistically significant difference was found between the two groups. This was with respect to the patellar groove and the shape of the medial condyle. The latter difference is consistent with bone remodelling as a knee stabilising mechanism.
CONCLUSIONS
Anatomical shape can be quantified using an uncomplicated statistical technique. It was used to quantify the shape of the distal femur and demonstrate shape differences associated with osteoarthritis of the knee.
目的
确定在二维轴向视图中，骨质象牙化股骨与非骨质象牙化股骨之间股骨远端形状的差异。
方法
从大量考古骨骼样本中选取52根非骨质象牙化股骨和16根骨质象牙化股骨进行比较。骨质象牙化被视为晚期骨关节炎的标志。在进行普氏叠加后，基于地标点的形状变异性通过主成分分析进行量化。
结果
两组之间存在统计学上的显著差异。这体现在髌股关节沟和内侧髁的形状上。后一种差异与作为膝关节稳定机制的骨重塑一致。
结论
解剖形状可以使用一种简单的统计技术进行量化。它被用于量化股骨远端的形状，并证明与膝关节骨关节炎相关的形状差异。
