High Return to Sport in Patients Over 45 Years of Age Undergoing Osteochondral Allograft Transplantation for Isolated Chondral Defects in the Knee.

In our series of patients 45 years and older who were treated with OCA for focal osteochondral injuries of the knee, we found a significant improvement in clinical outcome scores at a midterm follow-up of 37 months with no revision OCA procedures or conversion to any form of knee arthroplasty. In addition, a high percentage of patients were able to return to their preferred level of athletic activity.
