To provide morphological parameters of the normal tibial plateau by using three-dimensional (3D) CT and conventional radiography.We performed morphological measurements of tibial plateau on 157 consecutive adults using radiographic and 3D computed tomography (CT). Gender differences as well as differences in measurement techniques were statistically compared. Intraclass correlation coefficient (ICC) was used to evaluate intra- and interobserver reproducibility.The mediolateral dimensions, anteroposterior dimensions of tibial plateau showed significant differences according to gender, but no statistical differences were observed in coronal tibial slope as well as in posterior slope. There were significant differences in all parameters between 2 measurement techniques. 3D-CT measurements had a higher ICC in all parameters than that in the radiographs.This study confirmed that 3D morphological measurements of tibial plateau have more reproducibility than radiographs. Our data will be helpful for tibial component design and placement.
通过使用三维（3D）CT和传统X线摄影来提供正常胫骨平台的形态学参数。我们使用X线摄影和3D计算机断层扫描（CT）对157名连续的成年人进行了胫骨平台的形态学测量。对性别差异以及测量技术差异进行了统计学比较。组内相关系数（ICC）用于评估观察者内和观察者间的可重复性。胫骨平台的内外侧尺寸、前后尺寸根据性别显示出显著差异，但在冠状胫骨坡度以及后坡度方面未观察到统计学差异。两种测量技术在所有参数上均存在显著差异。3D-CT测量在所有参数上的ICC均高于X线片。本研究证实胫骨平台的3D形态学测量比X线片具有更高的可重复性。我们的数据将有助于胫骨假体的设计和放置。
