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 损伤患者体位定向错误的性别差异及其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 用临床适用的方法测量膝关节损伤患者的姿势方向（即身体各部分之间的对齐）的性别差异的研究有限。了解姿势定向和身体功能之间的关系可能有助于指导康复决策。目的是评估 (1) 前交叉韧带重建 (ACLR) 男性和女性在视觉评估姿势方向误差 (POE) 中的性别差异和 (2) POE 与客观和患者报告的身体功能之间的关联。方法 24 名女性和 29 名男性（平均 26.7（SD 6.5）岁）患有 ACLR。从五个任务的视频中对六个 POE（下肢和躯干）进行评分，计算 POE 分数（总分和子分）的难度各不相同。用单腿跳和侧跳来评估客观的身体功能。使用患者报告的结果测量 (PROM) 评估患者报告的身体功能。结果 女性的 POE 明显多于男性（中位数差异 5.5-25，p≤0.028）。在女性中，更多的 POE 与更短的跳跃距离和更少的侧跳相关（rs = -0.425 到 -0.518，p<0.038），但与男性无关（rs<0.301，p>0.05）。在任何性别中，POE 分数和 PROM 之间均未发现相关性（rs<–0.246，p>0.05）。结论 与男性相比，患有 ACLR 的女性似乎有更多的 POE，表明姿势方向更差。更多的 POE 与较差的跳跃表现相关，这表明 POE 分数可用作康复进展的标准。POE 分数和 PROM 之间缺乏关联表明这些措施是相辅相成的。数据只有在瑞典伦理委员会提出合理要求的情况下才能提供。向通讯作者 jenny.almqvist_nae@med.lu.se 发送电子邮件，索取相关数据。
