Chondrofix Osteochondral Allograft Prospective Study
Stopped early · Not applicable
Conditions studied: Articular Cartilage Disorder, Degeneration; Articular Cartilage, Chronic Cartilage Injury, Acute Cartilage Injury, Defect of Articular Cartilage
In brief
The overall study objective is to evaluate Chondrofix Osteochondral Allograft ("Chondrofix") for the repair of osteochondral lesions in the knee. This includes, but is not limited to primary cartilage lesion repair and revision of failed prior cartilage repair treatments. The study hypothesis is that Chondrofix Allograft will provide pain relief and functional improvement as demonstrated by a comparative analysis of baseline clinical evaluations at 24 months of follow-up.
