本研究的目的是描述中国人群股骨远端和胫骨近端的几何结构。使用CT图像构建20个女性和20个男性膝关节的三维模型。股骨远端形态学测量包括内外髁的内外径（ML）和前后径（MAP、MAP）、股骨长宽比（ML/MM）、内外髁宽度、髁间窝宽度、窝宽度指数（NWI）和股骨槽方向。股骨内外侧髁和胫骨平台的矢状面也进行了表征。结果表明，雌性大鼠股骨远端的大小明显小于雄性大鼠。此外，当通过BMI标准化时，与男性相比，女性的股骨远端（ML）显著更窄，MAP更短。在矢状面上，股骨远端外侧圆的半径明显小于内侧髁的半径。胫骨近端几何结构无显著性别差异。本研究的数据可能有助于对亚太地区患者的全膝关节假体尺寸/几何结构进行适当修改。
The goal of this study was to characterize the geometry of the distal femur and proximal tibia in the Chinese population. Three-dimensional models of twenty female and twenty male knees were constructed using CT images. The morphologic measurements of the distal femur included mediolateral (ML) and anteroposterior dimension of medial and lateral condyles (MAP, LAP), femoral aspect ratio (ML/LAP), medial and lateral condylar width, intercondylar notch width, notch width index (NWI), and trochlear groove orientation. The sagittal profiles of the medial and lateral femoral condyles and tibial plateaus were also characterized. The results showed that the size of the distal femur of the females was significantly smaller than that of the males. Furthermore, when normalized by LAP, the females had a significantly narrower distal femur (ML), and a shorter MAP compared to the males. In the sagittal plane, the radius of the lateral distal circle of the femur was significantly smaller than that of the medial condyle in both genders. There were no significant gender differences in the proximal tibial geometry. The data of the present study may enable suitable modification of total knee prosthesis sizing/geometry for Asia-Pacific patients.
