The aim of this study was to assess whether harvesting of two hamstring tendons (semitendinosus and gracilis) has the same rate of nerve injury as harvesting of the semitendinosus tendon alone, used as a triple graft.
Changes in sensitivity relating to injury of the infrapatellar branch of the saphenous nerve were evaluated in 110 patients six months after they underwent anterior cruciate ligament (ACL) reconstruction using hamstring tendons. They were divided into two groups: one in which only the semitendinosus was used and the other, the semitendinosus and gracilis.
The group in which only the semitendinosus was used as a graft presented a nerve injury rate of 36.1%. In the group in which the semitendinosus and gracilis tendons were used, 58.1% of the patients presented altered sensitivity. In the general assessment on all the patients, the nerve injury rate was 50.9%.
Harvesting the semitendinosus alone and using it in triple form is a viable option for ACL reconstruction and may give rise to fewer nerve injuries relating to branches of the saphenous nerve.
本研究旨在评估获取两条腘绳肌腱（半腱肌和股薄肌）与单独获取半腱肌肌腱作为三联移植物相比，神经损伤发生率是否相同。
对110例行腘绳肌腱前交叉韧带（ACL）重建术后6个月的患者，评估与隐神经髌下支损伤相关的感觉变化。他们被分为两组：一组仅使用半腱肌，另一组使用半腱肌和股薄肌。
仅使用半腱肌作为移植物的组神经损伤发生率为36.1%。在使用半腱肌和股薄肌肌腱的组中，58.1%的患者感觉发生改变。在对所有患者的总体评估中，神经损伤发生率为50.9%。
单独获取半腱肌并以三联形式使用它是ACL重建的一种可行选择，并且可能导致与隐神经分支相关的神经损伤更少。
