Abstract
Purpose
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 PFA prosthesis with an asymmetric trochlear component, performed between
June 2007 and July 2016 at a non-designer centre. The Patient Reported Outcome Measures
and patient satisfaction questionnaires were collected for final evaluation.
Results
A total of 103 PFA performed on 79 patients were evaluated. Median age at the time
of surgery was 58 years (range 42 to 78 years); the mean follow-up period was 6 years (range 2 to 11 years). Four knees were revised to Total Knee Arthroplasty for reasons not related
to the implant. The cumulative survival estimated by the Kaplan–Meier method was 94.3%
(95% confidence interval: 88.4%–100%). There were statistically significant improvements
in functional outcome scores.
Conclusion
This series of patients who underwent PFA with the asymmetric trochlear component
has shown promising mid-term results with no implant-related complications.
