Introduction

With the rising utilization of total joint arthroplasty, the role of simultaneous-bilateral surgery has expanding impact. The purpose of this study is to examine the risk of perioperative complications for this approach in total knee arthroplasty to inform shared decision making.

Methods

We used nation-wide linked discharge data from the Hospital Cost and Utilization Project from 2005–2014 comparing outcomes of simultaneous-bilateral and staged-bilateral total knee arthroplasties (TKAs). Hierarchical logistic regression analysis was used to compare mortality within 30 days, 90 days and 1 year, perioperative risks within 30–60 days, and infection and mechanical complications within 1 year.
