Among the graft options for anterior cruciate ligament reconstruction (ACLR), hamstring autografts are widely regarded as the preferred choice for primary ACLR among orthopedic surgeons worldwide. However, concerns persist regarding postoperative knee flexor weakness. We aimed to compare knee extensor and flexor strengths between hamstring autograft and tibialis anterior allograft groups in ACLR patients, who were propensity score-matched based on baseline characteristics. A retrospective analysis included 58 matched pairs who underwent isokinetic strength tests at 6 and 12 months post operation. Isokinetic muscle strength tests found no significant difference in knee extensor and flexor strength at 6 months post operation between the hamstring autograft and tibial anterior allograft groups. At 12 months, the hamstring autograft group exhibited significantly greater knee flexor deficit (total work and average power) compared to the allograft group, despite no differences in extensor strength or patient-reported outcomes. This study highlights the impact of hamstring autograft harvesting on muscle strength and recovery following ACLR in short-term period.
在前交叉韧带重建（ACLR）的移植选择中，腘绳肌自体移植被全球骨科医生广泛视为初次ACLR的首选。然而，术后膝关节屈肌无力的问题依然存在。我们旨在比较ACLR患者中腘绳肌自体移植组和胫骨前肌异体移植组之间的膝关节伸肌和屈肌力量，这些患者根据基线特征进行了倾向评分匹配。一项回顾性分析纳入了58对匹配的患者，他们在术后6个月和12个月接受了等速肌力测试。等速肌力测试发现，术后6个月时，腘绳肌自体移植组和胫骨前肌异体移植组之间的膝关节伸肌和屈肌力量没有显著差异。在12个月时，尽管伸肌力量或患者报告的结果没有差异，但腘绳肌自体移植组与异体移植组相比，膝关节屈肌缺陷（总功和平均功率）明显更大。这项研究强调了在短期内，腘绳肌自体移植取材对ACLR后肌肉力量和恢复的影响。
