Background:When treating end-stage osteoarthritis (OA) of the knee, total knee arthroplasty (TKA) is frequently used. The present study compared patellar resurfacing and non-resurfacing in patients undergoing bilateral total knee arthroplasty. Materials & Methods:72 patients scheduled fortotal knee arthroplasty of both genderswere divided into2 groups of 36 each. In group I, patients underwent resurfacing and group II patients underwent non- resurfacing of patella. During patellar resurfacing, the damaged surface of the patella was removed and replaced with metalimplant. Parameters such as Knee Society Score (KSS), Modified Samsung Medical Centre Score (MSMCS), Feller patellar score were recorded. Results: Group I had 20 males and 16 females and group II had 18 males and 18 females. Congruence angle was 2.31 degrees in group I and 2.58 degrees in group II. Patellar tilt angle was 2.01 degrees in group I and 2.15 degrees in group II. MSMCS pain was 1.45 in group I and 1.60 in group II, MSMCS function was 3.26 in group I and 3.59 in group II, KSS pain was 2.09 in group I and 2.82 in group II, KSS function was 3.14 in group I and 4.23 in group II. Feller patellar score was 2.83 in group I and 3.23 in group II. The difference was non- significant (P> 0.05). Conclusion: Both groups' clinical and radiological parameters were similar. Therefore, in patients undergoing bilateral total knee replacement, patellar resurfacing as well as non-resurfacing, can be done.
