Aim

Patellofemoral Arthroplasty (PFA) prosthesis with asymmetric trochlear component was introduced as an improvement from existing designs for surgical treatment of symptomatic isolated patellofemoral arthritis. The purpose of this study was to evaluate midterm results in patients who underwent PFA procedure using such prosthesis.

Methods

Our study involved a continuous retrospective cohort of patients who underwent PFA using Journey PFJ with asymmetric trochlear component, performed between June 2007 and October 2018 at a non-designer centre. The Patient Reported Outcome Measures and patient satisfaction questionnaires were collected for final evaluation.

Background

The R3 cementless acetabular system (Smith & Nephew, Memphis, Tennessee, United States) is a modular titanium shell with an asymmetric porous titanium powder coating. It supports cross-linked polyethylene, metal and ceramic liners with several options for the femoral head component. The R3 cup was first marketed in Australia and Europe in 2007. Two recent papers have shown high failure rates of the MoM R3 system with up to 24% (Dramis et al 2014, Hothi et al 2015). There are currently no medium term clinical papers on the R3 acetabular cup.

Objectives

The aim of the study is to review our results of the R3 acetabular cup with a minimum of 5 year follow up.
