Background: Total knee arthroplasty (TKA) is the recommended treatment to correct deformity, relieve pain, and restore normal biomechanics in osteoarthritis of the knee joint. The present study was conducted to compared patellar resurfacing and non-resurfacing in patients undergoing bilateral TKA. Materials & Methods: 80 patients selected for bilateral simultaneous TKA with posterior stabilized Hi flex fixed bearing knee were divided into two groups ie. group I patients underwent resurfacing and group II underwent non- resurfacing of patella. Patients were assessed using Knee Society Score (KSS), Modified Samsung Medical Centre Score (MSMCS), Feller patellar score. Results: KSS pain was 2.04 in group I and 2.81 in group II, KSS function was 3.12 in group I and 4.26 in group II, MSMCS pain was 1.46 in group I and 1.68 in group II, MSMCS function was 3.25 in group I and 3.62 in group II, Feller patellar score was 2.83 in group I and 3.21 in group II, congruence angle was 2.31 in group I and 2.51 in group II and patellar tilt angle was 2.07 in group I and 2.06 in group II. The difference was non- significant (P> 0.05). Conclusion: Clinical and radiological parameters were comparable in both groups. Clinical outcomes, patient satisfaction, revision rates and complication rates were similar in the resurfacing and nonresurfacing groups in a short-term follow up.
