Hamstring tendon grafts are a popular choice for anterior cruciate ligament (ACL) reconstruction. Typical morbidity reported after hamstring tendon harvest is muscle weakness in flexion, and whilst still a matter for debate, this morbidity may be greater if the gracilis tendon is harvested in addition to the semitendinosus. This study sought to comprehensively compare the outcome of ACL reconstructions in which the semitendinosus was harvested alone (ST group) or with the gracilis (ST/G group).
Twenty patients (ten ST, ten ST/G) were assessed with a variety of measures that included subjective scores, function, strength and tibial rotation as measured by gait analysis during a pivoting task.
Results showed that the graft diameter was significantly larger in the ST group, but there were no other differences between the groups for any other outcome measure.
Harvesting the gracilis in addition to semitendinosus does not appear to affect either the outcome or graft-related morbidity after hamstring ACL reconstruction.
腘绳肌腱移植物是前交叉韧带（ACL）重建的常用选择。腘绳肌腱采集后报告的典型发病率是屈曲时的肌肉无力，尽管仍存在争议，但如果在采集半腱肌肌腱的基础上再采集股薄肌肌腱，发病率可能会更高。本研究旨在全面比较单独采集半腱肌肌腱（ST 组）或同时采集半腱肌肌腱和股薄肌肌腱（ST/G 组）的 ACL 重建的结果。
对二十名患者（十名 ST 组，十名 ST/G 组）进行了多种评估，包括主观评分、功能、力量和步态分析测量的胫骨旋转，在枢轴任务中。
结果表明，ST 组的移植物直径明显更大，但在任何其他结果测量方面，两组之间没有其他差异。
在腘绳肌腱 ACL 重建中，在采集半腱肌肌腱的基础上再采集股薄肌肌腱似乎不会影响结果或与移植物相关的发病率。
