Tang XB, et al. - The clinical outcomes were compared between total knee arthroplasty (TKA) patients who underwent patella resurfacing vs. those who did not. According to findings, the Knee Society Clinical Score was significantly increased and the re-operative rates were reduced in the patella resurfacing group during 1 to 2 years of follow-up among patients with knee osteoarthritis (OA) who underwent TKA.
