The present study reports the early clinical results of 38 osteoarthritic patients (38 knees) who were treated by total knee
replacement in conjunction with patellofemoral fascial interposition arthroplasty (PFIA). After the femoral and tibial components
were inserted, a fasciotendinous graft was harvested from the anterior surface of the quadriceps tendon and sutured around
the articular surface of the patella. The patients were followed-up for a minimum of 24 months. The durability of the fascial
graft was assessed radiographically by addition of a wire suture marker placed into the fascia in the first five patients.
Patients were evaluated using the Hospital for Special Surgery (HSS) knee-rating system, and anterior knee pain was assessed
using specific patellofemoral-related questions. The average HSS knee score improved from 61 points preoperatively to 92 points
at 24 months’ follow-up (
P < 0.001). Twenty-five patients (65.7%) had anterior knee pain preoperatively, and seven patients (18.4%) revealed anterior
knee pain at their last visits (
P < 0.001). The position of the markers in the fascial grafts did not show any change during radiological follow-ups. Our data
suggest that, PFIA provides good pain relief and it may be an alternative resurfacing technique avoiding the complications
of patellar components.
