The July 1, 2015 JBJS contains a database-driven analysis by Duchman et al. of more than 78,000 patients who underwent primary total hip or knee arthroplasty between 2006 and 2012. The authors found that the 10% who were current smokers had a higher rate of wound complications (1.8%), compared with rates in former smokers (1.3%) and nonsmokers (1.1%). Current smokers had approximately twice the rate of deep wound infections compared with former smokers or nonsmokers. The authors note, however, that periprosthetic infections—a specific complication of great interest to orthopaedists and patients—are not captured by the National Surgical Quality Improvement Program (NSQIP) database from which the analyzed data was extracted.
