# Morphometric Analysis and Three-Dimensional Computed Tomography Reconstruction of Thai Distal Femur

### Comparison of the Morphometric Parameters with Thai Studies  
The morphometric parameters of the Thai population were compared with previous studies as shown in Table 4, which studied morphometric data of the Thai distal femur. The results of the comparison showed that the majority of the morphometric parameters except for the femoral aspect ratio (ML/AP, ML/MAP, and ML/LAP) were higher than those of the previous study. Those differences may arise as a result of different definitions of the measured parameters and measurement techniques. However, some parameters of previous studies have not been reported in comparison with the current study.
