Autologous Chondrocyte Implantation and Osteochondral Allograft Transplantation Render Comparable Outcomes in the Setting of Failed Marrow Stimulation

Abstract

ACI and OCA are both viable treatment options for chondral defects of the knee, even in the setting of a failed MST. Secondary ACI renders functional outcomes, subjective satisfaction, and reoperation and failure rates comparable with primary ACI and secondary OCA.
