Abstract

Introduction: Previous research has established that smoking significantly increases the complication rate of total knee arthroplasty (TKA). Risk of infection, prosthetic loosening, fractures, wound healing issues, and revisions are increased in smokers, but research is limited on the long-term clinical outcomes of pain, range of motion, stability, and functionality between smokers, nonsmokers, and former smokers, specifically utilizing Knee Society Scores (KSS).

Methods: This was a retrospective chart review of primary TKA patients (n = 203) at a single university hospital. The patients were divided by smoking status: nonsmoker, current smoker, or former smoker. One-way analysis of variance with associated f ratios was performed to assess variance in KSS by smoking status over time. Relative risk ratio analyses were employed to assess patients' predictive risk of acquiring postoperative infection and requiring additional surgery following TKA based on smoking status.

Results: Postoperative KSS were significantly lower in the smoker group compared to nonsmokers and former smokers at 6 weeks and 1 year. For every 20 months a former smoker used tobacco, an approximate 1-point decrease in KSS was expected. The relative risk ratios for postoperative infection rates and patients requiring additional surgery were 2.13 and 1.44, respectively, when current smokers were compared to nonsmokers.

Conclusions: This analysis found that current smokers had lower KSS and higher infection rates following TKA when compared to nonsmoking controls. In addition, increased duration of smoking was correlated with poorer outcomes within the former smoker group.

吸烟对全膝关节置换术患者临床效果的影响。
导言:既往研究证实吸烟显著增加全膝关节置换术(TKA)的并发症发生率。吸烟者感染、假体松动、骨折、伤口愈合问题和修复的风险增加,但对吸烟者、非吸烟者和前吸烟者之间疼痛、活动范围、稳定性和功能的长期临床结果的研究有限,特别是使用膝关节社会评分(KSS)。方法:回顾性分析一家大学医院的原发性TKA患者(n = 203)。患者按吸烟状况分为:不吸烟者、目前吸烟者和曾经吸烟者。采用相关f比值进行单因素方差分析,评估吸烟状况随时间变化对KSS的影响。采用相对风险比分析来评估基于吸烟状况的TKA患者术后感染和需要额外手术的预测风险。结果:吸烟组术后6周和1年的KSS明显低于不吸烟组和戒烟组。预计前吸烟者每使用烟草20个月,KSS就会减少大约1个点。当当前吸烟者与不吸烟者相比,术后感染率和需要额外手术的患者的相对风险比分别为2.13和1.44。结论:该分析发现,与不吸烟的对照组相比,目前吸烟者在TKA后的KSS较低,感染率较高。此外,在前吸烟者组中,吸烟持续时间的增加与较差的结果相关。
