To examine age- and sex-related differences in postoperative functional outcomes at approximately 6 months after anterior cruciate ligament reconstruction (ACLR).
In this study, patients who underwent primary ACLR performed a series of return-to-sport functional tests at 5 to 8 months after surgery. Functional tests included strength tests (knee extensors, knee flexors, hip abductors, and hip extensors), a balance test (Y-balance composite score), and hop tests (single, triple, crossover, and 6-m timed hop tests). Limb symmetry was calculated to compare the reconstructed limb with the uninvolved limb. A 2-way multivariate analysis of covariance was used, and effect size was calculated for data analysis.
A total of 176 subjects were included in this study. There were no significant interaction between age and sex on return-to-sport functional tests after ACLR. Also, no main effects of age and sex on return-to-sport functional tests were found in our data.
Age and sex do not significantly affect functional test performance after ACLR 6 months postoperatively.
Level III, retrospective review of prospective cohort study.
研究前交叉韧带重建（ACLR）术后约6个月时与年龄和性别相关的功能预后差异。
在本研究中，接受初次ACLR的患者在术后5至8个月进行了一系列恢复运动功能测试。功能测试包括力量测试（膝伸肌、膝屈肌、髋外展肌和髋伸肌）、平衡测试（Y平衡综合评分）和单腿跳测试（单腿跳、双腿跳、交叉跳和6米定时单腿跳测试）。计算肢体对称性以比较重建肢体与未受累肢体。采用双向多变量协方差分析，并计算效应量进行数据分析。
本研究共纳入176名受试者。ACLR术后恢复运动功能测试中，年龄和性别之间没有显著的交互作用。此外，在我们的数据中未发现年龄和性别对恢复运动功能测试的主要影响。
术后6个月，年龄和性别对ACLR后的功能测试表现没有显著影响。
III级，前瞻性队列研究的回顾性综述。
