Anterior cruciate ligament (ACL) reconstruction, using an ipsilateral hamstring graft, may necessitate an alternative graft source if the obtained graft is insufficient with regards to length or diameter. The study aims to determine the rate of insufficient ipsilateral hamstring graft harvesting in primary ACL reconstruction. Retrospective review of 50 consecutive primary ACL reconstructions performed by a single surgeon in the United Kingdom. In 3 of 50 cases, there was insufficient ipsilateral hamstring graft harvesting and a contralateral hamstring graft was used. In two cases, this was due to premature division of the ipsilateral hamstring tendons (3/100 harvested tendons). In one case, an adequate length of semitendinosus was obtained, but its central portion was too thin. Retrospective review of preoperative magnetic resonance imaging identified the thin part of the tendon in the latter case. Insufficient ipsilateral hamstring graft harvesting is a recognized, yet unusual intraoperative complication in primary ACL reconstruction. Presurgical planning as to how to manage such complications is essential.
前交叉韧带（ACL）重建术，使用同侧腘绳肌腱移植物，如果获得的移植物在长度或直径方面不足，则可能需要替代移植物来源。本研究旨在确定在初次 ACL 重建中同侧腘绳肌腱移植物采集不足的发生率。回顾性分析了英国一位外科医生连续进行的 50 例初次 ACL 重建病例。在 50 例中，有 3 例出现同侧腘绳肌腱采集不足，需要使用对侧腘绳肌腱。在 2 例中，这是由于同侧腘绳肌腱过早分开（3/100 采集的肌腱）。在 1 例中，获得了足够长度的半腱肌，但其中央部分太薄。回顾性分析术前磁共振成像发现了后一种情况下肌腱的薄部分。在初次 ACL 重建中，同侧腘绳肌腱移植物采集不足是一种公认但不常见的术中并发症。术前规划如何处理此类并发症至关重要。
