Despite the good clinical outcomes of osteochondral autograft transplantation (OAT), reports of re-arthroscopic findings after OAT have been limited to short-term, and there are no reports of findings after long-term follow-up. This is the first report that describes re-arthroscopic findings long-term after OAT.
A male patient underwent OAT on the lateral femoral condyle (LFC) of the knee and lateral meniscus (LM) repair at the age of 45. Eighty years after the primary surgery, he underwent re-arthroscopy because of cartilage injury on the medial femoral condyle (MFC) and LM tear. The re-arthroscopic findings showed the retained OAT plugs on LFC and severe damage of LM. After OAT on the LFC and meniscectomy of LM was performed, his knee symptoms improved, so the LFC that had undergone OAT 18 years previously was considered to be on a good clinical course.
OAT plugs were retained at the long-term follow-up while the repaired LM was severely damaged. The structural robustness of OAT was thought to be responsible for good long-term clinical outcomes.
尽管骨软骨自体移植术（OAT）取得了良好的临床效果，但关于OAT术后再次关节镜检查结果的报道仅限于短期，尚无长期随访结果的报道。这是首篇描述OAT术后长期再次关节镜检查结果的报告。
一名男性患者在45岁时接受了膝关节外侧股骨髁（LFC）的OAT及外侧半月板（LM）修复术。初次手术后80年，他因内侧股骨髁（MFC）软骨损伤和LM撕裂接受了再次关节镜检查。再次关节镜检查结果显示LFC上保留有OAT移植物，且LM严重受损。在对LFC进行OAT及切除LM后，他的膝关节症状有所改善，因此，18年前接受OAT的LFC被认为处于良好的临床进程。
在长期随访中，OAT移植物得以保留，而修复的LM严重受损。OAT的结构稳固性被认为是其长期良好临床效果的原因。
