The objective of this study was to correlate the data of the 6-month postoperative isokinetic muscle evaluation before resuming sports activities with the occurrence of ACL reconstruction rerupture after semitendinosus short graft.
From 2015 to 2018, all patients who were operated for an ACL reconstruction with a short semitendinosus autograft (TLS System) and who performed isokinetic tests on dynamometer at their 6th postoperative month were included in this study. The follow-up was prospective with the measurement of epidemiological, radiographic, and isokinetic parameters at 6 months of the ACL reconstruction. The cohort was divided into 2 groups: one group without an ACL reconstruction rerupture (Group 1) and the second group with a rerupture (Group 2).
One hundred and four patients were analyzed with an average follow-up of 42.3 months (Minimum: 24; Maximum: 63.5), of which 11 patients (10.6%) had an ACL reconstruction rerupture. Group 1 consisted of 93 patients with an average age of 26.5 ± 9.0 years old who did not have an ACL reconstruction rerupture with an average follow-up of 41.6 ± 12.1 months. Group 2 consisted of 11 patients with an average age of 22.7 ± 6.1 years old, who had an ACL reconstruction rerupture with an average follow-up of 44.8 ± 11.3 months. Concerning extension force recovery, the ratio between operated and healthy knee was 81.8% ± 32.0 for Group 1, and 53.4% ± 20.6 for Group 2 ( = .035). A statistically significant difference was also found ( = .0017) during 60°/s flexion isokinetic test between the two groups.
This study revealed a significant link between muscle weakness in flexion and extension during 60°/s isokinetic test at 6 months of ACL reconstruction and semitendinosus autograft rerupture. Patients with an ACL reconstruction retear had inferior muscle dynamometric recovery results at 6 months before resuming sports activities.
Level III, prognostic, retrospective cohort study.
本研究的目的是将恢复体育活动前6个月的等速肌力评估数据与半腱肌短移植物后前交叉韧带重建再断裂的发生情况相关联。
2015年至2018年，所有接受半腱肌自体短移植物（TLS系统）进行前交叉韧带重建手术且在术后第6个月在测力计上进行等速测试的患者均纳入本研究。随访是前瞻性的，测量前交叉韧带重建6个月时的流行病学、影像学和等速参数。队列分为2组：一组无前交叉韧带重建再断裂（第1组），第二组有再断裂（第2组）。
分析了104例患者，平均随访42.3个月（最小值：24；最大值：63.5），其中11例患者（10.6%）发生了前交叉韧带重建再断裂。第1组由93例患者组成，平均年龄26.5±9.0岁，无前交叉韧带重建再断裂，平均随访41.6±12.1个月。第2组由11例患者组成，平均年龄22.7±6.1岁，发生了前交叉韧带重建再断裂，平均随访44.8±11.3个月。关于伸展力恢复，第1组手术侧与健侧膝关节的比值为81.8%±32.0，第2组为53.4%±20.6（P = .035）。两组在60°/s屈曲等速测试期间也发现有统计学显著差异（P = .0017）。
本研究揭示了前交叉韧带重建6个月时60°/s等速测试中屈伸肌无力与半腱肌自体移植物再断裂之间存在显著关联。前交叉韧带重建再撕裂的患者在恢复体育活动前6个月的肌肉测力恢复结果较差。
III级，预后性回顾性队列研究。
