Non-Tobacco Nicotine Dependence and Rates of Postoperative Complications in Total Knee Arthroplasty: A Propensity-Matched Comparison

Tobacco use elevates the incidence of postoperative complications and remains a key modifiable risk factor of perioperative surgical optimization. It remains unclear whether non-tobacco nicotine dependence confers an increased risk of surgical complications. This study evaluates postoperative complications in patients with non-tobacco nicotine dependence for total knee arthroplasty (TKA).
