Abstract
INTRODUCTION: Chondral defects of the knee are common and their treatment is challenging. SOURCE OF DATA: PubMed, Google scholar, Embase and Scopus databases. AREAS OF AGREEMENT: Both autologous matrix-induced chondrogenesis (AMIC) and membrane-induced autologous chondrocyte implantation (mACI) have been used to manage chondral defects of the knee. AREAS OF CONTROVERSY: It is debated whether AMIC and mACI provide equivalent outcomes for the management of chondral defects in the knee at midterm follow-up. Despite the large number of clinical studies, the optimal treatment is still controversial. GROWING POINTS: To investigate whether AMIC provide superior outcomes than mACI at midterm follow-up. AREAS TIMELY FOR DEVELOPING RESEARCH: AMIC may provide better outcomes than mACI for chondral defects of the knee. Further studies are required to verify these results in a clinical setting.
