Purpose: Previous studies have shown that ACI treatment following a Subchondral Marrow Stimulation (SMS) procedure caused a failure rate three to five times higher than performing a primary ACI procedure. This study sought to determine the effects of performing an OCA transplantation after SMS procedures versus as a primary procedure.
Take Away: Contrary to results demonstrated with ACI, the treatments performed in both groups provided reliable and effective options. In both there was improvement in pain and function and long-term survivorship with insignificant statistical differences between groups.
