本研究旨在研究内翻和正常膝关节形态，以确定可能影响膝关节置换术对线或内翻膝关节设计的差异。 分析膝内翻和正常膝关节的CT扫描，并将几何形状、点和轴独立地拟合到股骨和胫骨。然后将这些点投影到三个解剖平面上，以测量两组之间的变化。与正常膝关节相比，内翻膝关节的股骨前倾角较小（p < 0.0001），内侧伸展关节面较大（p < 0.05）。在胫骨中，发现内翻膝关节的结节外旋（12°），冠状面斜率（p = 0.001）和伸展关节面角（p = 0.002）显著增加。该研究强调了两组之间的差异和相似之处，这提高了对手术干预和部件放置或内翻膝关节设计期间所需变化的认识。这与患者专用工具和植入物的设计特别相关。诊断研究，III级。
The aim of the study was to investigate varus and normal knee morphologies to identify differences that may affect knee replacement alignment or design for varus knees. Computed tomography scans of varus and normal knees were analyzed, and geometric shapes, points and axes were fit to the femur and tibia independently. These points were then projected in the three anatomical planes to measure the variations between the two groups. In the femur, varus knees had less femoral anteversion (p < 0.0001) and a larger medial extension facet (p < 0.05) compared with normal knees. In the tibia, the tubercle was found to be externally rotated in varus knees (12°), with a significant increase in the coronal slope (p = 0.001) and the extension facet angle (p = 0.002). The study highlighted the differences and similarities found between the two groups, which raises awareness on changes required during surgical intervention and component placement or design for a varus knee. This is particularly relevant for the design of patient-specific instrumentation and implants. Diagnostic study, Level III.
