Clinical Study of Patellar Resurfacing and Non-resurfacing in Total Knee Arthroplasty

Total Knee Arthroplasty Clinical Trial

Official title:
A Prospective Randomized Clinical Study of Patellar Resurfacing and Non-resurfacing in One-stage Bilateral Total Knee Arthroplasty

Clinical Trial Summary

The literature regarding resurfacing of the patella in total knee arthroplasty has conflicting conclusions. This study assesses medium-term clinical results of total knee arthroplasties performed with and without the patellar resurfacing in patients undergoing single-staged bilateral total knee arthroplasty in a randomized controlled, clinical study at a minimum of 5 years follow-up.

Clinical Trial Description

Sixty-six patients (132 knees) underwent primary single-staged bilateral total knee arthroplasty for osteoarthritis. Patients were randomized to receive resurfacing or retention of the patella. All patients received the Scorpio NRG knee prosthesis. Evaluations were done preoperatively and yearly, up to a minimum of 5 years postoperatively. Knee Society Score and Feller Score outcomes were measured. Anterior knee pain, the clunk of patella, and patient satisfaction questionnaires were completed. ;
