To measure the angular relationships of distal femoral rotational axes in 100 normal Indian knees.
42 men and 8 women aged 26 to 40 (mean, 31) years, with 100 normal non-arthritic knees were recruited. Anatomic landmarks were measured using computed tomography. They included the posterior condylar axis, the transepicondylar axis, the anteroposterior axis (Whiteside's line), the posterior condylar angle (PCA), the Whiteside-epicondylar angle (W-EP), and the Whiteside-posterior condylar angle (W-PC).
The mean PCA, W-EP, and W-PC were 5, 90.8, and 95.8 degrees, respectively. The mean femorotibial alignment was 179.6 degrees. The differences between the left and right sides were significant only for the WEP and W-PC. Only the PCA and W-EP were weakly correlated (r=0.338, p=0.001).
There are differences in distal femoral rotational axes among Indian, Caucasian, and Japanese knees. Our data can be used to evaluate changes in those axes in ageing or arthritic patients.
测量100例正常印度人膝关节中股骨远端旋转轴的角度关系。
招募了42名男性和8名女性，年龄在26至40岁（平均31岁）之间，共有100个正常非关节炎膝关节。使用计算机断层扫描测量解剖标志。这些标志包括后髁轴、髁上轴、前后轴（怀特赛德线）、后髁角（PCA）、怀特赛德-髁上角（W-EP）和怀特赛德-后髁角（W-PC）。
平均PCA、W-EP和W-PC分别为5度、90.8度和95.8度。平均股胫对线为179.6度。左右侧之间的差异仅在WEP和W-PC方面具有统计学意义。只有PCA和W-EP呈弱相关（r = 0.338，p = 0.001）。
印度人、白种人和日本人的膝关节在股骨远端旋转轴方面存在差异。我们的数据可用于评估衰老或关节炎患者这些轴的变化。
