A comparative study of patellar resurfacing and non resurfacing in patient undergoing Bilateral Total Knee Arthroplasty

Abstract

Objective: To investigate the impact of patellar replacement on total knee arthroplasty (TKA) efficacy.

Methods: A study included 30 patients (60 knees) with osteoarthritis who underwent TKA. One knee received patellar replacement (randomly selected), and the other did not. Recorded parameters included intraoperative blood loss, operation time, Knee Society Scoring System (KSS), Artificial Joint Forgotten Index (FJS), and various knee-related observations. Follow-up lasted 2-4 years.

Results: Operation time for replacement side: (126±14) min, non-replacement side: (112±11) min (t=5.103, P=0.030). No significant intraoperative blood loss difference. Follow-up showed no prosthesis loosening. The replacement side had lower VAS scores at 6 months and 2 years (Z=–1.997, P=0.046; Z=–2.197, P=0.028). Better self-perception at 6 weeks for replacement side (χ2=4.271, P=0.039).

Conclusion: Patients with patellar replacement in TKA reported an overall better experience than those without replacement.
