Abstract
The purpose of this study was to compare wound complication rates after total ankle replacement in 3 groups of patients based on tobacco status. The total cohort was divided into 3 groups based on tobacco history. Group 1 included patients who were actively tobacco users. Group 2 included patients with a history of tobacco user. Group 3 served as the control group and included patients who had never used tobacco. Available charts were reviewed for patients who underwent primary total ankle arthroplasty by 1 surgeon. Patient demographics, tobacco history, and postoperative wound complications were recorded. A total of 114 patients with tobacco history were available for follow-up and were included in this study, which ranged from March 2012 to July 2017. Group 1 included 11 active smokers. Group 2 included 38 former smokers, and group 3 had a total of 65 never smokers included. The average follow-up was 28 months for group 1 (range 10-55 months), 34.1 months for group 2 (range 12-60 months), and 32.8 months for group 3 (range 11-60 months). The wound complication rate was noted to be statistically significant when comparing active smokers to never smokers using Fisher’s exact test (P = .0223). When comparing former smokers with never smokers, the difference in wound complication rate did not reach statistical significance (P = 0.7631). All patients underwent at least 1 concomitant procedure at the time of initial ankle replacement. Our findings show that total ankle replacement wound healing complication rates are significantly higher in active tobacco users. There was no significant difference in wound healing complications when comparing former tobacco users versus never tobacco users.
