Unique combination of patellofemoral joint arthroplasty with Osteochondral Autograft Transfer System (OATS) - a case series of six knees in five patients.
Patellofemoral arthroplasty (PFA) is an accepted procedure for the treatment of isolated patellofemoral osteoarthritis. However its failure rate has been attributed to progressive femorotibial arthritis. Autologous osteochondral transplantation is an established procedure for the repair of focal cartilaginous defects on the medial and lateral femoral condyles. We present our case series of six knees in five patients where we combined the two procedures and extended the indication for PFA and delayed the need for total knee arthroplasty (TKA) in all but one patient over a mean follow up period of 3.8 years.
