36 patients scheduled to undergo cartilage or osteochondral repair were randomized to either a synthetic resorbable biphasic implant (TruFit Plug) group or a microfracture surgery group. The purpose of this study was to determine the clinical outcomes and assess the MRI findings of these two methods of treatment for chondral or osteochondral defects. Results of this study found that both TruFit and microfracture surgery improved clinical scores within the first postoperative year, although findings progressively declined at 2 and 3 years follow-up in each group. No significant differences were noted between groups at 2 years.
