Increased Risk of Short-Term Complications in Smokers Undergoing Primary Unicompartmental Knee Arthroplasty

Abstract

The effects of smoking on unicompartmental knee arthroplasty (UKA) are unknown. The purpose of this study was to evaluate the effects of smoking on short-term outcomes following primary UKA. A query of the National Surgical Quality Improvement Project (NSQIP) database was used to identify cases of primary UKA performed during years 2006 to 2017. Patient demographics, operative times, and postoperative complications were compared between smoking and nonsmoking cohorts. Descriptive statistics, univariate analyses, and multivariate analyses were conducted to evaluate the effects of smoking on primary UKA. A total of 10,593 cases of UKA were identified; 1,046 of these patients were smokers. Univariate analysis demonstrated smokers to have higher rates of any complication (4.6 vs. 3.3%, p = 0.031), any wound complication (1.82 vs. 0.94%, p = 0.008), deep wound infection (0.57 vs. 0.13%, p = 0.006), and reoperation (1.34 vs. 0.68%, p = 0.018) relative to nonsmokers. Multivariate analysis demonstrated smokers to have higher rates of any wound complication (odds ratio [OR] = 1.79; 95% confidence interval [CI]: 1.06–2.95) and reoperation (OR = 2.11; 95% CI: 1.12–3.97). Smokers undergoing primary UKA are at higher risk for any wound complication and reoperation relative to nonsmokers in the first 30 days postoperatively. Further studies evaluating the long-term effects of smoking on outcome following UKA, as well as the impact of smoking cessation on outcomes following UKA, are needed.

Effect of tobacco usage on surgical site wound problems after primary total hip and total knee arthroplasty: A meta‐analysis

“…Following an assessment of 2035 pertinent examinations, 15 tests released between 2003 and 2023 were included in the meta‐analysis since they matched the criteria for inclusion 6–20 . Table 2 summarises the findings of these investigations.…”

“…inclusion. [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] Table 2 summarises the findings of these investigations. A total of 560 819 personals with PTH&TKA were in the used studies' starting point, 73 673 of them were smokers and 487 146 were non-smokers.…”

“…Fifteen studies from 2003 to 2023 were enrolled for the present meta‐analysis comprising 560 819 personals with PTH&TKA in the used studies' starting point, 73 673 of them were smokers and 487 146 were non‐smokers 6–20 . The examined data revealed that in personals with PTH&TKA, smokers had significantly higher SSWPs compared with non‐smokers, and current smokers had significantly higher SSWPs compared with non‐smokers and former smokers; however, former smokers and non‐smokers had no significant difference in SSWPs.…”

“…дольше, чем без нее. Однако не было обнаружено достоверных различий в частоте краткосрочных послеоперационных осложнений, частоте ревизионных вмешательств и среднем времени пребывания пациентов в стационаре между парциальной артропластикой с компьютерной навигацией и прецизионной хирургической техникой [44].…”

Reduced Early Revision Surgery and Medical Complications in Computer-assisted Knee Arthroplasty Compared With Non–computer-assisted Arthroplasty

“…Although some studies have found improved complication rates with computer-assisted patellofemoral arthroplasty and unicompartmental knee arthroplasty (CA-UKA), others have found no difference. 12–15 There are minimal data regarding outcomes of computer-assisted patellofemoral arthroplasty and computer-assisted bicompartmental knee arthroplasty (CA-BKA). 16–18…”
