Aim The present study aimed to establish the normal range of the posterior tibial slope (PTS) angle in the Saudi adult population and to identify whether there was an association between the angle and gender or age. Materials and methods A total of 524 normal knee radiographs of 410 patients aged 18-85 years were included in the study. The PTS was measured using the anterior tibial cortex method. Data were matched with gender and age for statistical analysis. Results The mean physiological PTS angle was 13.6 ± 3.4˚ (range: 3.8-23.9˚). Age and gender did not influence the PTS value (P >0.05). The two-way analysis of variance (ANOVA) test showed no interaction effect between age and gender on the PTS (P >0.05). Conclusions This study provided a reference range for the normal PTS among Saudis, which can assist in decision-making during different knee procedures. The PTS value did not significantly differ between male and female subjects, and there was no significant association between the PTS angle and age.
目的 本研究旨在确定沙特成年人群胫骨后倾坡度（PTS）角的正常范围，并确定该角度与性别或年龄之间是否存在关联。材料与方法 本研究纳入了410例年龄在18 - 85岁患者的524张正常膝关节X线片。采用胫骨前缘皮质法测量PTS。将数据与性别和年龄进行匹配以进行统计分析。结果 平均生理性PTS角为13.6±3.4˚（范围：3.8 - 23.9˚）。年龄和性别对PTS值无影响（P>0.05）。双向方差分析（ANOVA）测试显示年龄和性别对PTS无交互作用（P>0.05）。结论 本研究为沙特人正常PTS提供了参考范围，可协助在不同膝关节手术中进行决策。PTS值在男性和女性受试者之间无显著差异，且PTS角与年龄之间无显著关联。
