Recently, there has been renewed interest in patellofemoral arthroplasty,
with the development of newer designs that have produced more consistent
outcomes; however, historically, the reported results of this procedure have
varied widely1. The
purpose of this article is to analyze trends in the published results of this
procedure, to identify critical factors contributing to the success or failure
of these operations, and to relate the initial lessons that we have learned
from our six-year clinical experience with the Avon patellofemoral
arthroplasty (Stryker Orthopaedics, Mahwah, New Jersey). Indications,
contraindications, mid-term follow-up results, and ways to avoid pitfalls are
delineated.
It is our intent that, with this information, surgeons will have a more

patients with isolated patellofemoral arthritis or advanced, refractory,
symptomatic patellofemoral chondromalacia.
