背景:本研究比较了机器人辅助全膝关节置换术(RA-TKA)与导航引导全膝关节置换术(NG-TKA)的术后结果。使用全国住院患者样本(NIS)数据,它提供了术后并发症的分析,死亡率,住院费用和住院时间。
方法:该研究使用2016年至2019年的NIS数据分析了217,715例患者(81,830例RA-TKA;135,885例NG-TKA)。通过国际疾病分类确定了选择性TKA患者,第十次修订代码。统计分析,包括逻辑回归建模,使用社会科学统计软件包和MATLAB进行。
结果:RA-TKA患者年龄较小(66.1vs.67.1年,p<0.0001),死亡率相似(0.024%vs.0.018%,p=0.342),但住院时间较短(LOS)(1.89vs.2.1天,p<0.0001)。RA-TKA(66,180美元)和NG-TKA(66,251美元,p=0.669)之间的平均总费用相当。RA-TKA显示血液相关并发症的发生率较低(11.67%vs.14.19%,p<0.0001),肺水肿(0.0306%vs.0.066%,p<0.0001),深静脉血栓形成(0.196%vs.0.254%,p=0.006)和急性肾损伤(AKI)(1.356%vs.1.483%,p=0.016)。
结论:RA-TKA减少了术后并发症和LOS而不增加成本,强调这项技术在病人护理中的相关性。
方法:三级。
BACKGROUND: This study compares postoperative outcomes of robotic-assisted total knee arthroplasty (RA-TKA) versus navigation-guided total knee arthroplasty (NG-TKA). Using Nationwide Inpatient Sample (NIS) data, it provides an analysis of postoperative complications, mortality, hospital costs and duration of stay.
METHODS: The study analysed 217,715 patients (81,830 RA-TKA; 135,885 NG-TKA) using NIS data from 2016 to 2019. Elective TKA patients were identified through the International Classification of Diseases, 10th Revision codes. Statistical analyses, including logistic regression modelling, were performed using Statistical Package for the Social Sciences and MATLAB.
RESULTS: RA-TKA patients were younger (66.1 vs. 67.1 years, p < 0.0001) and had similar mortality rates (0.024% vs. 0.018%, p = 0.342) but shorter length of stay (LOS) (1.89 vs. 2.1 days, p < 0.0001). Mean total charges were comparable between RA-TKA ($66,180) and NG-TKA ($66,251, p = 0.669). RA-TKA demonstrated lower incidences of blood-related complications (11.67% vs. 14.19%, p < 0.0001), pulmonary oedema (0.0306% vs. 0.066%, p < 0.0001), deep vein thrombosis (0.196% vs. 0.254%, p = 0.006) and acute kidney injury (AKI) (1.356% vs. 1.483%, p = 0.016).
CONCLUSIONS: RA-TKA reduces postoperative complications and LOS without increasing costs, highlighting the relevance of this technology in patient care.
METHODS: Level III.
