This report illustrates the outcome of a free human autogenous semitendinosus tendon graft placed in the knee under arthroscopic control for anterior cruciate ligament reconstruction. The tendon graft showed signs of injury by localized loss of normal histochemical staining properties. The cellularity was not diminished in an early (3-week) specimen. The resultant composite anterior cruciate ligament consisted of two distinct areas: tendon graft and surrounding fibrous tissue. The tendon maintained gross and microscopic characteristics of the original tendon. The tissue surrounding the tendon graft had a disorganized cellular pattern and hypervascularity. The tendon graft in this study did not show gross or microscopic evidence of death and reorganization. Previous reports have led to erroneous conclusions concerning the outcome of a free tendon graft due to inaccurate biopsy site of the reorganizing fibrous tissue surrounding the tendon graft.
本报告阐述了在关节镜控制下将游离的人体自体半腱肌腱移植至膝关节用于前交叉韧带重建的结果。肌腱移植物出现了正常组织化学染色特性局部丧失的损伤迹象。在早期（3周）标本中细胞数量并未减少。最终形成的复合前交叉韧带由两个不同区域组成：肌腱移植物和周围的纤维组织。该肌腱保留了原始肌腱的大体和微观特征。肌腱移植物周围的组织具有紊乱的细胞模式和血管增生。本研究中的肌腱移植物未显示出大体或微观层面的坏死和重塑迹象。既往报告由于对肌腱移植物周围重塑纤维组织活检部位不准确，导致了关于游离肌腱移植物结果的错误结论。
