Posterior tibial slope (PTS) influences knee kinetics and kinematics. The purpose of this study was to investigate morphology and variation within a sample of the black and white male and female population.
480 randomly selected lateral knee radiographs were included. The anterior tibial cortex angle (ATC), proximal anatomical tibial axis angle (PTAA) and the posterior tibial cortex angle (PTC) were measured using ImageJ 1.53e software. Between group differences (black male and females, white males and females) were analysed using one-way ANOVA.
Significant differences between the three different angles (p = 0.0001, F = 50.68) but no between group differences for the individual angle measurements (ATC, PTAA, PTC) between ethnicity and sex. For ATC, the angles between groups ranged from 14.20 + 2.81 degrees (Females Black), 14.62 + 3.6 degrees (Male Black), 15.18 + 3.68 degrees (Male White) to 15.54 + 3.21 degrees (Females White). For PTAA, the angles between groups ranged from 10.37 + 2.59 degrees (Females Black), 10.61 + 3.27 degrees (Male Black), 10.68 + 3.27 degrees (Male White) to 10.83 + 3.27 degrees (Females White). For PTC, the angles between groups ranged from 6.07 + 3.13 degrees (Females White), 6.13 + 3.7 degrees (Male White), 6.35 + 2.67 degrees (Females Black) to 6.62 + 3.16 degrees (Male Black).
This study could not establish differences in posterior tibial slope angles between males and females and ethnicity. Significant differences between ATC, PTAA and PTC angles were observed and PTC angles were smaller when compared to PTAA and ATC angles. The ATC angles ranged between 13.18 and 16.57 degrees, the PTAA angles ranged 9.38-11.87 degrees and the PTC angles ranged between 5.03 and 7.62 degrees for all groups.
胫骨后倾角（PTS）会影响膝关节的动力学和运动学。本研究的目的是调查黑人和白人男性及女性样本中的形态学及变异情况。
纳入480张随机选取的膝关节外侧X线片。使用ImageJ 1.53e软件测量胫骨前缘皮质角（ATC）、近端解剖胫骨轴角（PTAA）和胫骨后缘皮质角（PTC）。使用单因素方差分析分析组间差异（黑人男性和女性、白人男性和女性）。
三个不同角度之间存在显著差异（p = 0.0001，F = 50.68），但种族和性别之间的个体角度测量值（ATC、PTAA、PTC）不存在组间差异。对于ATC，组间角度范围从14.20±2.81度（黑人女性）、14.62±3.6度（黑人男性）、15.18±3.68度（白人男性）到15.54±3.21度（白人女性）。对于PTAA，组间角度范围从10. [此处原文有误，应为10.37]±2.59度（黑人女性）、10.61±3.27度（黑人男性）、10.68±3.27度（白人男性）到10.83±3.27度（白人女性）。对于PTC，组间角度范围从6.07±3.13度（白人女性）、6.13±3.7度（白人男性）、6.35±2.67度（黑人女性）到6.62±3.16度（黑人男性）。
本研究未能确定男性与女性以及不同种族之间胫骨后倾角的差异。观察到ATC、PTAA和PTC角度之间存在显著差异，并且与PTAA和ATC角度相比，PTC角度较小。所有组的ATC角度范围在13.18至16.57度之间，PTAA角度范围在9.38 - 11.87度之间，PTC角度范围在5.03至7.62度之间。
