Infection is a rare occurrence after revision anterior cruciate ligament reconstruction (rACLR). Because of the low rates of infection, it has been difficult to identify risk factors for infection in this patient population. The purpose of this study was to report the rate of infection following rACLR and assess whether infection is associated with patient- and surgeon-dependent risk factors. We reviewed two large prospective cohorts to identify patients with postoperative infections following rACLR. Age, sex, body mass index (BMI), smoking status, history of diabetes, and graft choice were recorded for each patient. The association of these factors with postoperative infection following rACLR was assessed. There were 1423 rACLR cases in the combined cohort, with 9 (0.6%) reporting postoperative infections. Allografts had a higher risk of infection than autografts (odds ratio, 6.8; 95% CI, 0.9-54.5; p = .045). Diabetes (odds ratio, 28.6; 95% CI, 5.5-149.9; p = .004) was a risk factor for infection. Patient age, sex, BMI, and smoking status were not associated with risk of infection after rACLR.
在接受前交叉韧带重建（rACLR）后，感染是一种罕见的情况。由于感染率较低，因此很难确定该患者人群中感染的危险因素。本研究的目的是报告 rACLR 后的感染率，并评估感染是否与患者和外科医生相关的危险因素有关。我们回顾了两个大型前瞻性队列，以确定接受 rACLR 后发生术后感染的患者。记录了每位患者的年龄、性别、体重指数（BMI）、吸烟状况、糖尿病史和移植物选择。评估了这些因素与 rACLR 后术后感染的关系。在合并队列中有 1423 例 rACLR 病例，其中有 9 例（0.6%）报告发生了术后感染。同种异体移植物的感染风险高于自体移植物（优势比，6.8；95%置信区间，0.9-54.5；p=0.045）。糖尿病（优势比，28.6；95%置信区间，5.5-149.9；p=0.004）是感染的危险因素。患者年龄、性别、BMI 和吸烟状况与 rACLR 后感染风险无关。
