Short-term clinical outcome of atellocollagen-associated autologous chondrocyte implantation for the repair of chondral defects

摘要

Introduction: A number of treatment procedures have been developed for chondral defects in the knee joint. The authors previously reported the prospective multicenter clinical trial of atellocollagen-associated autologous chondrocyte implantation (ACI) for the repair of full-thickness chondral defects of the knees. In this procedure, the clinical scores based on Lysholm scale and knee-function scale improved significantly. Therefore, this atellocollagen-associated ACI (JACC: Japan Tissue Engineering, Gamagori, Japan) is approved by the Japanese Health Insurance since 2013. The purpose of this study was to evaluate short-term clinical outcome and complication in patients undergoing atellocollagen-associated ACI for the repair of chondral defects of the knees.
