Simultaneous bilateral knee arthroplasty (SBTKA) in octogenarians is controversial. Our purpose was to review the outcomes of octogenarians undergoing SBTKA. All patients greater than 80 years of age who underwent SBTKA by a single surgeon were retrospectively evaluated. Fifty-six patients with an average age of 82.5 years were identified. Twelve postoperative complications occurred. Three were serious; two non-fatal PEs and one wound debridement. Minor complications included UTI, decubitus ulcer, DVT, confusion, transfusion reaction and ileus. Average postoperative survival was 7.4 years. No deaths occurred within 30 days postoperatively. Simultaneous bilateral total knee arthroplasty can be a safe and effective option for octogenarians. Complications and mortality are not higher for SBTKA compared to UTKA in this population.
