Introduction

The optimal treatment for isolated patello-femoral arthritis is unclear. Patello-femoral arthroplasty (PFA) may offer superior knee function in isolated patello-femoral osteoarthritis compare to TKA. The literature is controversial for patient outcomes in PFA. Some reports showed improved outcomes while others were disappointing. We assessed our outcomes to try to identify causes for poor outcomes.

Methods

The Trent Arthroplasty was established in 1990 to collect prospective data on knee arthroplasty surgery. Data is entered by surgeons at the time of surgery, with patient consent. PFA constitute less than 1% of the arthroplasties performed in this region. Patients were sent self-administered outcome forms 1 year post-op. Re-operation and revision procedures were reported. 334 PFA have been registered from 17 hospitals. 79% were female patients with 43% of the patients aged 55 years or less, suggesting dysplasia as the cause of their osteoarthritis. Age range 28–94 yrs (SD 11.8 yrs). The implants were Stryker Avon 236, Corin Leicester 47, Link Lubinus 24, Smith & Nephew Journey 10, DePuy LCS 7, Wright FPV 2, other 8.
