Abstract
Abstract
Given the growing rate of revision total knee arthroplasties (TKAs), it is important to understand the potential risk factors associated with postoperative complications. The aim of this study was to determine the role of operative time in postoperative complications in revision TKA. A retrospective cohort study was performed using data from the American College of Surgeons National Surgical Quality Improvement Program database. Patients who had undergone revision TKA between 2007 and 2016 were identified and analyzed based on operative time. The effect of operative time on postoperative complications was examined using multinomial multivariate analysis. A total of 14,769 revision TKA patients were included. On adjusted multivariate analysis, each additional 15 minutes of operative time increased the likelihood of wound complications (odds ratio, 1.023; P=.020), postoperative blood transfusion (odds ratio, 1.169; P
