Reconstructive surgery of the anterior cruciate ligament (ACL) of the knee in young active patients is a routine procedure, but with certain risks that need to be taken into account. Peroperative patellar fracture after bone-patellar tendon-bone autograft harvesting is a rare complication, which can significantly impair the functional outcome of ACL single-bundle reconstruction. We report the case of a patient presenting with disabling patellofemoral syndrome 3 years after arthroscopic ACL reconstruction by bone-tendon-bone autograft, revealing unnoticed mal-union of a iatrogenic sagittal patellar fracture. Patellar osteotomy corrected this painful iatrogenic patellar instability.
膝关节前交叉韧带（ACL）的重建手术在年轻活跃的患者中是一种常规手术，但存在一定的风险需要考虑。骨-髌腱-骨自体移植物采集后髌前骨折是一种罕见的并发症，可显著影响 ACL 单束重建的功能结果。我们报告了 1 例患者在关节镜下 ACL 重建术后 3 年出现失能性髌股关节综合征，发现了未被注意到的医源性矢状位髌骨骨折的愈合不良。髌骨切开术纠正了这种疼痛性医源性髌股关节不稳定。
