Abstract

Patellofemoral (PF) osteoarthritis (OA) is a relatively prevalent disease, afflicting up to 24% of women and 11% of men over the age of 55 years who have symptomatic knee OA.The aims of this narrative overview is to help to determine the place of patellofemoral arthroplasty (PFA) in the management of isolated PF-OA, and to describe the clinical outcomes of PFA for the treatment of isolated PF degenerative OA of the knee. A Cochrane Library and PubMed (MEDLINE) search related to the role of PFA in PF-OA was performedSeveral reports have found that PFA is an efficacious management for isolated PF-OA. Moreover, a systematic review reported fairly good outcomes of PFA survivorship and functional results at short- and mid-run follow-up in the setting of isolated PF-OA. Success of PFA depends upon precise patient selection rather than prosthetic failure or wear. In many reports, the principal reason of PFA failure is progression of tibiofemoral OA. In recent times, promising outcomes have been produced by the association of PFA and unicompartmental knee arthroplasty (UKA). In cvonclusion, patients with isolated PF-OA with intense anterior knee pain may be aspirants for PFA. The success of the surgical technique and the long-run survivorship of the prosthesis rely on good surgical procedure and adherence to rigorous indications and contraindications in patient selection. Newer prostheses have also contributed to ameliorated results. PFA is an option for younger patients with isolated PF-OA.
