Osteochondral Allograft Transplant for Focal Cartilage Defects of the Femoral Condyles: Clinically Significant Outcomes, Failures, and Survival at a Minimum 5-Year Follow-up

Purpose: To evaluate clinically significant outcomes, failures, and graft survival rates after osteochondral allograft (OCA) transplant of the femoral condyles at a minimum of 5-year follow-up.

Summary:

  • The mean follow-up time was 7.7 years.
  • All patient-reported outcomes showed statistically significant improvement between preoperative baseline and final follow-up.
  • Based on the International Knee Documentation Committee Score (IKDC), 75% of patients achieved a minimal clinically important difference (MCID), and 58.9% of patients achieved a significant clinical benefit at final follow-up.
  • The OCA survival rate was 98.7% at 1 year, 95.6% at 2 years, 91.2% at 3 years, 86.2% at 5 years, and 81.8% at 10 years.
  • Majority of patients in this study underwent a previous knee surgery prior to OCA transplant, with this study further confirming the role of OCA as a reliable salvage procedure.


JRF Ortho Take Away: OCA transplant of the femoral condyle was associated with significant improvement in clinically significant outcomes at a mean follow-up time of 7.7 years. With a survival rate of 86.2% at 5 years and 81.8% at 10-year follow-up, OCAs are a durable mid-to-long-term option for cartilage restoration of the femoral condyle.
