[Objective]To compare the early clinical outcomes of primary total knee arthroplasty(TKA)with or without patellar resur-facing.[Methods]A retrospective study was conducted on of 45 patients(52 knees)who received primary TKA for knee osteoarthritis in our departments from February 2018 to December 2020.According to doctor-patient discussion,24 patients(28 knees)had patellar resur-facing replacement,while other 21 patients(24 knees)had not patellar resurfacing replacement in TKA.The perioperative and follow-up re-sults were compared between the two groups.[Results]The operation was successfully completed in both groups,and there were no signifi-cant differences in operation time,intraoperative blood loss,incision length and postoperative ambulation between the two groups(P＞0.05).All patients in both groups were followed up for more than 3 months,and got significant improvement in terms of VAS and KSS scores at the last follow-up compared with those before surgery.However,there were no significant differences between the two groups in VAS score[(1.6±1.0)vs(1.8±0.9),P=0.781]and KSS score[(86.3±7.9)vs(84.6±7.9),P=0.865]at the latest follow-up.[Conclusion]There is no signif-icant difference in term of the early consequence of primary TKA with or without patellar resurfacing replacement.
