Abstract

Purpose

To examine age- and sex-related differences in postoperative functional outcomes at approximately 6 months after anterior cruciate ligament reconstruction (ACLR).

Methods

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.

Results

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.

Conclusions

Age and sex do not significantly affect functional test performance after ACLR 6 months postoperatively.

Level of Evidence

Level III, retrospective review of prospective cohort study.

前十字韧带重建术后五到八个月的功能测试未发现年龄或性别差异

目的研究前交叉韧带重建（ACLR）术后约 6 个月时，术后功能结果中与年龄和性别相关的差异。方法在这项研究中，接受初级 ACLR 的患者在术后 5 到 8 个月时进行了一系列恢复运动功能测试。功能测试包括力量测试（膝关节伸肌、膝关节屈肌、髋关节外展肌和髋关节伸肌）、平衡测试（Y-平衡综合评分）和跳跃测试（单跳、三跳、交叉跳和6米计时跳跃测试）。通过计算肢体对称性来比较重建肢体与未受影响肢体。数据分析采用双向多变量协方差分析法，并计算效应大小。年龄和性别在前交叉韧带置换术后恢复运动功能测试中没有明显的交互作用。结论前交叉韧带置换术后 6 个月，年龄和性别对功能测试成绩无明显影响。
