The purposes of this study were to determine the incidence of infection requiring reoperation after arthroscopic knee surgery during a 6-year period and to compare infection rates across different age groups, genders, geographic regions of the United States, and Current Procedural Terminology (CPT) codes through a retrospective review of a large insurance company database.
A retrospective review of an insurance company database was performed for all knee arthroscopies performed in the United States from 2004 to 2009. The database was first queried for all knee arthroscopies, and the number of those cases requiring additional surgery for infection within 30 days was determined to calculate the incidence of infection. The incidence was stratified by gender, age group, region within the United States, and CPT code. A separate analysis for procedures using allografts was also performed.
A total of 432,038 arthroscopic surgeries were performed, and the number of infections requiring drainage was 638, for an overall incidence of infection from 2004 to 2009 of 0.15%. Among adults, men were affected almost twice as often as women (P < .001), and among children, boys were affected almost 3 times as often as girls (P < .001). A decreasing incidence was noted in patients 60 years or older between 2004 and 2009 (P = .01). Overall, the incidence did not significantly vary by age, region, or CPT codes that specified the implantation of allograft tissue. Compared with diagnostic arthroscopy, the relative risk of infection was higher for CPT-29889 (posterior cruciate ligament reconstruction).
The incidence of infection requiring reoperation after knee arthroscopy from 2004 to 2009 was 0.15%. The incidence was higher among male patients in both the adult and pediatric populations. The incidence of infection decreased from 2004 to 2009 in patients 60 years or older. Among adult patients, the incidence did not vary by age, by region, or by CPT codes that involved implantation of allografts.

本研究旨在确定在 6 年期间接受关节镜膝关节手术后需要再次手术的感染发生率，并通过回顾性分析大型保险公司数据库，比较不同年龄组、性别、美国地理区域和当前操作术语 (CPT) 代码的感染率。
对 2004 年至 2009 年在美国进行的所有膝关节关节镜手术的保险公司数据库进行回顾性分析。首先对数据库进行查询，以确定所有膝关节关节镜手术中 30 天内需要再次手术治疗感染的病例数，以计算感染发生率。按性别、年龄组、美国地区和 CPT 代码对发生率进行分层。还对使用同种异体移植物的手术程序进行了单独分析。
共进行了 432038 例关节镜手术，需要引流的感染数为 638 例，2004 年至 2009 年的总体感染发生率为 0.15%。在成年人中，男性感染的几率几乎是女性的两倍（P <.001），而在儿童中，男孩感染的几率几乎是女孩的三倍（P <.001）。2004 年至 2009 年间，60 岁及以上患者的感染发生率呈下降趋势（P=.01）。总体而言，感染发生率不因年龄、地区或指定植入同种异体组织的 CPT 代码而有显著差异。与诊断性关节镜检查相比，CPT-29889（后交叉韧带重建）的感染相对风险更高。
2004 年至 2009 年膝关节关节镜手术后需要再次手术的感染发生率为 0.15%。男性患者在成年和儿童人群中的感染发生率更高。2004 年至 2009 年间，60 岁及以上患者的感染发生率呈下降趋势。在成年患者中，感染发生率不因年龄、地区或涉及同种异体植入物的 CPT 代码而有所不同。
