Results at 5-year follow-up showed the Femora Patella Vialli patellofemoral joint prosthesis yielded “moderate” outcomes, according to recently published results.

Researchers identified 43 Femora Patella Vialli patellofemoral joint prostheses (Wright Medical, United Kingdom ) implanted in 32 patients from April 2004 to December 2012. The mean follow-up was 65 months. Investigators reviewed outcomes for patients after they underwent patellofemoral arthroplasty. Intention to revise the implant was the primary outcome. Other outcomes included the Oxford and Kujala outcome scores.

Results showed one patient was lost to follow-up. For the remaining patients, the mean flexion was 110° at the final follow-up. Of the 42 knees, five needed revision to a total knee replacement due to progressive tibiofemoral osteoarthritis. Revisions were performed at a mean of 56 months. No radiographic loosening was seen in any case. Investigators noted the mean Oxford score improved from 18 points to 29 points. The Kujala score improved from 35 points to 58 points. – by Monica Jaramillo
