Abstract

Purpose

The primary aim was to evaluate the functional impact of adding lateral extra-articular tenodesis (LET) to an anterior cruciate ligament (ACL) reconstruction (ACLR). The secondary aim was to assess whether LET provides benefits in muscle strength, patient-reported outcome measures (PROMs) and return to sport (RTS) pass rate, as well as to examine the influence of meniscal injury on performance in ACLR patients.

Methods

A retrospective cohort of prospectively collected data on all ACL procedures was performed at AZ Delta Roeselare between 2017 and 2019. The patients followed a 7-month rehabilitation programme and were assessed according to standardised RTS criteria. Patients were divided into two groups according to whether they received LET technique or not, and then each group was further divided based on the presence or absence of meniscal injury. The primary outcomes were the functional movement tests including agility t-test and hop tests. The secondary outcomes were the muscle strength, PROMs and RTS pass rate. A two-way ANCOVA test or a non-parametric test was used to investigate clinical and functional differences among the four groups.

Results

A total of 105 ACL injury patients who underwent ACLR with or without LET were included. The cohort consisted of 74 males and 31 females, with an average age of 25.0 ± 6.2 years. Significantly statistical differences among groups were found for the functional movement tests at 7 months post-operatively in favour of the ACLR with LET groups compared with isolated ACLR groups (agility t-test: 95% confidence interval [CI] 0.3–1.2, p = 0.003; cross-over hop test: injured leg: 95%CI 20–86, p = 0.002; uninjured leg: 95%CI 12–76, p = 0.008; triple hop test: injured leg: 95%CI 7–77, p = 0.019). There were no significant differences in muscle strength, PROMs or RTS pass rates among the groups. Meniscal injury had no significant effect on any variable of interest.

Conclusion

The addition of a LET procedure to an ACLR showed important improvements in functional movement outcomes at 7 months post-operatively with no negative effect on muscle strength or PROMs.

外侧关节外肌腱固定术改善前交叉韧带重建患者的功能运动结果

目的：主要目的是评估在前交叉韧带（ACL）重建（ACLR）中加入外侧关节外肌腱固定术（LET）对功能的影响。第二个目的是评估LET是否在肌肉力量、患者报告的结果测量（PROMs）和恢复运动（RTS）通过率方面提供益处，以及检查半月板损伤对ACLR患者表现的影响。方法回顾性队列，前瞻性收集2017年至2019年在AZ Delta Roeselare进行的所有ACL手术的数据。患者遵循7个月的康复计划，并根据标准化RTS标准进行评估。根据患者是否接受LET技术分为两组，再根据是否存在半月板损伤进一步分为两组。主要结果为功能性运动测试，包括敏捷性t检验和跳跃测试。次要指标为肌力、PROMs、RTS通过率。采用双向ANCOVA检验或非参数检验来调查四组患者的临床和功能差异。结果共纳入105例ACL损伤患者行ACLR伴或不伴LET。男性74例，女性31例，平均年龄25.0±6.2岁。术后7个月的功能运动测试结果显示，与孤立ACLR组相比，LET组更有利于ACLR(敏捷性t检验：95%置信区间[CI] 0.3-1.2, p = 0.003；交叉跳跃试验：伤腿：95%CI 20-86， p = 0.002；未伤腿：95%CI 12-76， p = 0.008；三跳试验：腿部损伤：95%CI 7-77， p = 0.019)。两组间肌肉力量、PROMs和RTS通过率均无显著差异。半月板损伤对任何感兴趣的变量均无显著影响。结论：在ACLR中加入LET手术对术后7个月的功能运动结果有重要改善，对肌肉力量或PROMs没有负面影响。证据等级三级。
