The aim of this study is to investigate risk factors of the development of joint adhesion after autologous chondrocyte implantation (ACI) of the knee. We reviewed 232patient cases with knee ACI operated on from 1995 June to 2006 December, which had undergone second-look arthroscopy after the initial ACI surgery. All patients were examined with magnetic resonance imaging before the second-look arthroscopy. Based on the results of this study, we conclude that the two and more grafts, implantation at patellofemoral joint, and additional lateral release procedure appear to be risk factors of adhesion after ACI of the knee.
