我们的目的是获得正常髌股关节的测量值，分析性别和个体差异。此外，胫骨结节-转子沟（TT-TG）距离的绝对值和指标在临床应用中仍存在争议。仍然需要一种更好的方法来实现精确的预测。78例无膝关节病变的参与者的78个膝关节被纳入本横断面研究。对所有参与者进行CT扫描，并使用Mimics和SolidWorks软件构建三维膝关节模型。我们测量并分析了19个参数，包括TT-TG距离以及髌骨、股骨、胫骨和胫骨托的尺寸和形状。采用LASSO回归法预测TT-TG距离的正常值。男性的尺寸参数、TT-TG距离和股骨长宽比显著大于女性（所有p值均< 0.05）。然而，在控制了年龄、身高和体重的偏倚后，男女之间的TT-TG距离和前后尺寸没有显著差异（所有p值> 0.05）。股骨前偏心距与其他指标之间的Pearson相关系数始终低于0.3，表明无相关性或相关性较弱。对于沟角和Wiberg指数观察到类似的结果。使用LASSO回归，我们获得了四个参数来预测TT-TG距离（R2 = 0.5612，p < 0.01），以达到最佳的准确性和方便性。提供了中国人群髌股形态的规范性数据。对于相同的内外侧尺寸，女性的前后尺寸比男性厚。不仅要注意性别差异，而且要注意个体差异，特别是前髁和滑车。此外，本研究为准确预测TT-TG距离提供了一种新的方法。在线版本包含补充材料，可通过10.1186/s12891-021-04454-8获得。
Our objective was to obtain normal patellofemoral measurements to analyse sex and individual differences. In addition, the absolute values and indices of tibial tuberosity-trochlear groove (TT-TG) distances are still controversial in clinical application. A better method to enable precise prediction is still needed. Seventy-eight knees of 78 participants without knee pathologies were included in this cross-sectional study. A CT scan was conducted for all participants and three-dimensional knee models were constructed using Mimics and SolidWorks software. We measured and analysed 19 parameters including the TT-TG distance and dimensions and shapes of the patella, femur, tibia, and trochlea. LASSO regression was used to predict the normal TT-TG distances. The dimensional parameters, TT-TG distance, and femoral aspect ratio of the men were significantly larger than those of women (all p values < 0.05). However, after controlling for the bias from age, height, and weight, there were no significant differences in TT-TG distances and anterior-posterior dimensions between the sexes (all p values > 0.05). The Pearson correlation coefficients between the anterior femoral offset and other indexes were consistently below 0.3, indicating no relationship or a weak relationship. Similar results were observed for the sulcus angle and the Wiberg index. Using LASSO regression, we obtained four parameters to predict the TT-TG distance (R2 = 0.5612, p < 0.01) to achieve the optimal accuracy and convenience. Normative data of patellofemoral morphology were provided for the Chinese population. The anterior-posterior dimensions of the women were thicker than those of men for the same medial-lateral dimensions. More attention should be paid to not only sex differences but also individual differences, especially the anterior condyle and trochlea. In addition, this study provided a new method to predict TT-TG distances accurately. The online version contains supplementary material available at 10.1186/s12891-021-04454-8.
