Bilateral Total Knee Arthroplasty (TKA) in a One-Stage Procedure Versus Two-Stage Procedure: A Retrospective Study.

This retrospective study aims to evaluate the safety and functional outcomes of simultaneous bilateral total knee arthroplasty (TKA) compared to two-stage bilateral TKA procedures. Osteoarthritis is the leading cause of knee joint replacement globally, so we sought to determine whether the one-stage approach could be deemed non-inferior to the two-stage method in terms of perioperative complications and postoperative recovery. We analyzed two cohorts: 43 patients underwent one-stage bilateral TKA, while 66 patients received two-stage TKA.
