Background: Isolated patellofemoral arthritis represents around 15 to 20% of all patients with knee pain. Patellofemoral Arthroplasty has become an interesting option for severe patellofemoral joint arthritis because of the good results obtained with new implants designs.

Methods: This retrospective study has revised 117 medical records of patients submitted to patellofemoral joint arthroplasty between 2007 and 2017 at Sacre Coeur and Jean Talon Hospitals in Montreal - QC, Canada.

Results: The study has shown patellofemoral arthrosis in 52,9% of cases, followed by trochlear dysplasia (41,8%) and these are the most important factor to guide patients to surgery specially in young women (2,3:1/F:M) around fifties (50,3 yo average). Patellofemoral arthroplasty is preceded by another surgical treatment in 24,6% of cases. Patellar malalignment is present in 86,3% of patients divided in lateral displacement (24,7%), tilt patellar lateral (41,1%) and patellar height (20,5%). Patellar overstuffing is the most frequent early complication observed in 12,8% of patients. Other clinical complications had the same rate for TKA and UKA.

Conclusion: Patellofemoral Arthroplasty is a less aggressive option to treat isolated PF Arthrosis presenting the same rates of Total Knee Arthroplasty. Patellar alignment should be evaluated preoperatively and reestablished to reach good results.
