Despite increasing interest in the anatomic importance of the meniscal insertion, little information is available regarding the relationship between the tibial slope and the meniscal insertion. Lateral radiographs and MRI sagittal images from 100 healthy and young patients were used in this study. Patients without deformation, meniscal pathology, or previous surgery to the ipsilateral knee were included in this study. We measured the angle between a line tangent to the medial and lateral tibial slope and the proximal tibial anatomical axis using a lateral radiographs. We also measured the angle between the tangent line to the medial and lateral tibial insertion of the meniscus and the proximal tibial anatomical axis using sagittal MRI images. The measurements were carried out twice by two observers. Inter-observer reliability ranged from 0.98 to 0.99 and intra-observer reliability ranged from 0.83 to 0.94. For each observer, the mean differences between measurements made using radiographs and MRI images were 16.4 degrees and 16.4 degrees on the lateral side, respectively, and 6.0 degrees and 5.9 degrees on the medial side, respectively. There was a statistically significant difference between measurements made using radiographs and MRI images (p < 0.001). However, the Pearson's correlation coefficient between the measurements made using radiographs and MRI images did not show a linear correlation. The measurements of posterior slope on lateral radiographs images and meniscal insertion on sagittal MRI images were reproducible and reliable. Differences in measurements ranged from 15 degrees to 17 degrees on the lateral side and from 5 degrees to 6 degrees on the medial side, with 95% confidence intervals. However, there was no statistical correlation between the measurements made using lateral radiographs and MRI images.
尽管人们对半月板附着处的解剖学重要性越来越感兴趣，但关于胫骨斜率与半月板附着处之间的关系的信息却很少。本研究使用了 100 名健康年轻患者的外侧射线照片和 MRI 矢状图像。本研究纳入了无畸形、半月板病变或同侧膝关节手术史的患者。我们使用外侧射线照片测量了沿内侧和外侧胫骨斜率以及胫骨近端解剖轴的切线之间的角度。我们还使用 MRI 矢状图像测量了沿内侧和外侧半月板胫骨附着处的切线与胫骨近端解剖轴之间的角度。这些测量由两名观察者进行了两次。观察者间可靠性范围为 0.98 至 0.99，观察者内可靠性范围为 0.83 至 0.94。对于每个观察者，射线照片和 MRI 图像测量之间的平均差异分别为 16.4 度和 16.4 度，在外侧，分别为 6.0 度和 5.9 度，在内侧。射线照片和 MRI 图像测量之间存在统计学上的显著差异（p < 0.001）。然而，射线照片和 MRI 图像测量之间的 Pearson 相关系数并未显示线性相关性。外侧射线照片图像上的后斜率测量值和矢状 MRI 图像上的半月板附着处测量值具有可重复性和可靠性。外侧差异范围为 15 度至 17 度，内侧差异范围为 5 度至 6 度，置信区间为 95%。然而，射线照片和 MRI 图像测量之间没有统计学相关性。
