BACKGROUND: Revision of failed surgical treatments of @entity1843 ( @entity1843 ) lesions remains a challenge without an obvious solution. The aim of this study was to evaluate seven consecutive @entity1 undergoing osteochondral grafting of a failed @entity1843 repair. METHODS: The mean time from surgery to the latest evaluation was 7.0years. IKDC, WOMAC, Tegner, and MRI studies were collected both preoperatively and during follow-up. Evaluation of the graft was assessed using the magnetic resonance observation of cartilage repair tissue (MOCART) grading system. RESULTS: Over the course of the study period, five @entity1 required additional surgery with a study median of one additional surgery (range, zero to 3). At most recent follow-up, there was significant improvement from preoperative values in median IKDC (p=0.004), WOMAC (p=0.030), and Tegner (p=0.012). Complete cartilage fill and adjacent tissue integration of the paste graft were observed by MRI evaluation in five of the seven (71.4%) @entity1 . Definitive correlation between clinical outcomes and MRI scores was not observed. CONCLUSIONS: This study shows promising results of osteochondral grafting as a viable option for the revision of failed @entity1843 repairs; however, more @entity1 are needed to fully support its efficacy in these challenging failed revision cases.
