A 67-year-old immunocompromised woman presented with 2 weeks of atraumatic knee pain 4 months after a primary total knee arthroplasty. The patient had a history of consuming unpasteurized dairy products and horse rearing. The patient underwent a successful irrigation, debridement, polyethylene liner exchange, and adjunct antibiotic therapy for a periprosthetic joint infection (PJI). Intraoperative cultures grew Listeria monocytogenes.
Immmunocompromised patients are at increased risks for PJI. Those patients who engage in rearing animals and consuming unpasteurized dairy products are at increased risk for atypical infections. It is vital to recognize patients who are at increased risk for infection and council them on risk aversion behavior.
一位 67 岁免疫功能低下的女性，在初次全膝关节置换术后 4 个月出现无创伤性膝关节疼痛 2 周。患者有食用未经巴氏消毒的乳制品和饲养马匹的病史。患者成功地进行了冲洗、清创、聚乙烯衬垫更换和辅助抗生素治疗，以治疗假体周围关节感染（PJI）。术中培养出单核细胞增生李斯特菌。
免疫功能低下的患者发生 PJI 的风险增加。那些饲养动物和食用未经巴氏消毒乳制品的患者发生非典型感染的风险增加。识别感染风险增加的患者并就风险回避行为对其进行咨询至关重要。
