Objectives There is limited research on sex differences in postural orientation (ie, alignment between body segments) in people with knee injury measured with a clinically applicable method. An understanding of the relationship between postural orientation and physical function may help guide decision making in rehabilitation. The aims were to evaluate (1) sex differences in visual assessment of Postural Orientation Errors (POEs) and (2) the association between POEs and objective and patient-reported physical function, in men and women with anterior cruciate ligament reconstruction (ACLR). Methods Twenty-four women and 29 men (mean 26.7 (SD 6.5) years) with ACLR were included. Six POEs (lower extremity and trunk) were scored from a video of five tasks with varying difficulty to compute POE scores (total and subscores). Objective physical function was evaluated with the single-leg hop for distance and side hop. Patient-reported physical function was evaluated using patient-reported outcome measures (PROMs). Results Women had significantly more POEs than men (median difference 5.5–25, p≤0.028). More POEs were associated with shorter hop distance and fewer side hops in women (rs= −0.425 to −0.518, p<0.038), but not in men (rs<0.301, p>0.05). No associations were found between POE scores and PROMs, in either sex (rs< –0.246, p>0.05). Conclusions Women with ACLR seem to have more POEs compared with men, indicating worse postural orientation. More POEs were associated with worse hop performance, suggesting that POE scores may be used as criteria for rehabilitation progression. The lack of associations between POE scores and PROMs indicate that these measures complement each other. Data will only be available on reasonable request due to the Swedish Ethical committee.

ACL损伤患者姿势取向错误的性别差异以及与客观和患者报告功能的关联：一项探索性横断面研究

目的对于通过临床适用的方法测量的膝关节损伤患者的姿势取向（即身体各部位之间的排列）的性别差异的研究很少。了解姿势取向和身体机能之间的关系可能有助于指导康复决策。目的是在前交叉韧带重建术（ACLR）的男性和女性中评估（1）姿势评估错误（POE）的视觉评估中的性别差异，以及（2）POE与客观和患者报告的身体机能之间的关联。方法包括24例ACLR女性和29例男性（平均26.7（SD 6.5）岁）。从五个任务的视频中对六个POE（下肢和躯干）进行了评分，难度各不相同，以计算POE得分（总分和亚分）。用单腿跳的距离和侧跳来评估客观的身体机能。使用患者报告的结局指标（PROM）评估患者报告的身体功能。结果女性的POE明显高于男性（中位数差异5.5-25，p≤0.028）。女性中，更多的POE与更短的跳跃距离和更少的侧跳相关（rs = -0.425至-0.518，p <0.038），而男性则不相关（rs <0.301，p> 0.05）。男女性别均未发现POE评分与PROM之间存在关联（rs <–0.246，p> 0.05）。结论与男性相比，ACLR女性的POE似乎更多，表明姿势取向较差。更多的POE与较差的啤酒花表现相关，这表明POE分数可以用作康复进展的标准。POE分数和PROM之间缺乏关联，表明这些衡量标准是相辅相成的。只有在得到瑞典道德委员会的合理要求后，才能提供数据。通过电子邮件发送给相应的作者jenny.almqvist_nae@med.lu.se，以请求相关数据。
