Comparison of Clinical Results between Simultaneous Bilateral Total Knee Arthroplasty and Unilateral Total Knee Arthroplasty

Abstract

We compared the clinical results of simultaneous bilateral total knee Arthroplasty (TKA) and unilateral TKA. Between January 2005 and May 2011 we performed 29 simultaneous bilateral TKAs and 65 unilateral TKAs. We found a low incidence of serious complications and no significant difference in clinical results, operation time, amount of bleeding or quantity of transfused blood between the two procedures. We consider that simultaneous bilateral TKA is a more useful method because the recovery period after treatment is shortened.
