Abstract
This study stratifies complication risk in primary total joint arthroplasty (TJA) based on body mass index (BMI). Demographics, co-morbidities, perioperative variables, and complications were reviewed for 22,808 patients. Chi-squared, one-way ANOVA, univariate and multivariable regression analysis were performed. Increasing BMI led to an increase (P<0.05) in combined complications, acute kidney injury (AKI), cardiac arrest (CA), reintubation, reoperation, and superficial infection (SI). Univariate analysis for BMI>40 revealed an increase in combined complications (15.21-vs-17.40%), AKI (1.93-vs-3.87%), CA (0.22-vs-0.57%), reintubation (0.47-vs-0.95%), reoperation (2.36-vs-3.37%), and SI (0.82-vs-1.65%). Multivariable regression showed BMI>40 as an independent predictor for combined complications (OR=1.18), AKI (OR=1.79), CA (OR=3.94), reintubation (OR=2.56), reoperation (OR=1.44), and SI (OR=2.11). Morbid obesity confers increased risk for complications in TJA. Published by Elsevier Inc.Entities:
