To characterize arthroplasty procedures, calculate the surgical infection rate and identify related risk factors.
This was a retrospective cohort study. Data on operations performed between 2010 and 2012 were gathered from documental sources and were analyzed with the aid of statistical software, using Fisher's exact test, Student's t test and the nonparametric Mann-Whitney and Wilcoxon tests.
421 total arthroplasty procedures performed on 346 patients were analyzed, of which 208 were on the knee and 213 on the hip. It was found that 18 patients (4.3%) were infected. Among these, 15 (83.33%) were reoperated and 2 (15.74%) died. The prevalence of infection in primary total hip arthroplasty procedures was 3%; in primary total knee arthroplasty, 6.14%; and in revision of total knee arthroplasty, 3.45%. Staphylococcus aureus was prevalent. The length of the surgical procedure showed a tendency toward being a risk factor (p = 0.067).
The prevalence of infection in cases of primary total knee arthroplasty was greater than in other cases. No statistically significant risk factors for infection were identified.
描述关节成形术的手术过程，计算手术感染率并确定相关危险因素。
这是一项回顾性队列研究。收集了2010年至2012年间进行手术的相关数据，这些数据来源于文档资料，并借助统计软件，采用Fisher精确检验、Student t检验以及非参数Mann-Whitney和Wilcoxon检验进行分析。
对346例患者实施的421例全关节成形术进行了分析，其中208例为膝关节手术，213例为髋关节手术。发现18例患者（4.3%）发生感染。其中，15例（83.33%）接受了再次手术，2例（15.74%）死亡。初次全髋关节置换术的感染率为3%；初次全膝关节置换术为6.14%；全膝关节置换翻修术为3.45%。金黄色葡萄球菌最为常见。手术时间显示出成为危险因素的趋势（p = 0.067）。
初次全膝关节置换术的感染率高于其他情况。未发现具有统计学意义的感染危险因素。
