Abstract
Introduction: Autologous matrix-induced chondrogenesis (AMIC) is a single-procedure technique used in the repair of chondral and osteochondral defects, particularly in the knee. Since its introduction, there has been an increasing body of literature exploring its outcomes not only in the knee but in other joints, including the hip, ankle, and shoulder. This review explores present evidence of the AMIC as well as comparing it to other cartilage repair techniques, including microfracture, autologous chondrocyte implantation (ACI), and autograft transplantation. Materials and Method: A literature search was completed with two specific goals: first, to identify present available literature for AMIC and its outcomes; second, to identify literature comparing the outcomes of AMIC to other cartilage repair techniques. Results: This review had identified that AMIC has superior functional outcomes compared to microfracture in the knee in both medium- and long-term follow-up. Within other joints, medium-term outcomes are favorable, but longer-term data are still required. Present literature demonstrates superior functional outcomes in AMIC compared to both matrix induced ACI and autologous minced cartilage implantation. Results from ACI and osteochondral autograft transplant are similar to those achieved with AMIC. Conclusion: AMIC represents a viable and effective single-stage technique for the management and osteochondral defects. There is long-term data supporting its superiority to microfracture alone; however, additional evidence comparing outcomes to other repair techniques is still required to establish AMIC as the standard of care for chondral and osteochondral defect management.
