A retrospective evaluation of our institution patellofemoral arthroplasty cases from 2006 to 2018 was performed; the n sample after applying exclusion and inclusion criteria was 21. All patients excepting one were female with a median age of 63 (20–78). A Kaplan–Meier survival analysis at ten years was calculated.

The progression of the osteoarthritis in the tibiofemoral compartment was the main cause (50% of revision surgeries).
