Osteochondral Allograft Transplantation of the Femoral Trochlea

Purpose: To evaluate osteochondral allograft (OCA) clinical outcomes and survivorship in the femoral trochlea.


  • 29 knees treated for a cartilage lesion limited to the femoral trochlea with a fresh OCA
  • Lesions were typically large in size with an average area of 6.1 cm2 with bony involvement
  • Graft survivorship was 100% at 5 years and 91.7% at 10 years
  • Most patients were able to participate in at least mild activities with minimal pain while some were able to return to high-level activities
  • Many had follow-up over 10 years and 84.6% of patients were rated as good or excellent at latest follow-up

Take Away: The use of a fresh OCA in the femoral trochlea yielded excellent clinical outcomes as well as improved pain, function and had high patient satisfaction.  These results are equivalent to what can be achieved with a fresh OCA transplantation in the femoral condyle
