title: Comparison of MRI and arthroscopy after autologous chondrocyte implantation in patients with osteochondral lesion of the talus.
abstract: No reported postoperative evaluation method is accurately correlated with the clinical outcome of repaired cartilage after autologous chondrocyte implantation. This study investigated the correlation of follow-up magnetic resonance imaging (MRI) evaluation and arthroscopic findings to the clinical outcome of surgically repaired osteochondral lesion of the talus with autologous chondrocyte implantation using the modified magnetic resonance observation of cartilage repair tissue (MOCART) scoring system.The study group comprised 21 consecutive patients with an osteochondral lesion of the talus who underwent autologous chondrocyte implantation. One year postoperatively, a follow-up MRI was obtained and a second-look arthroscopy was performed. Although the arthroscopic findings of the repaired osteochondral lesion of the talus showed better correlation with the clinical outcome when used with the modified MOCART scoring system, the higher correlation occurred only within a statistical error range, thus making the correlation not significantly different from the one determined on MRI. Therefore, a second-look arthroscopy is not necessary to evaluate the repaired talar cartilage after an autologous chondrocyte implantation. Magnetic resonance imaging is a useful method for long-term follow-up of patients with osteochondral lesions of the talus.
