Case:
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.
Conclusion:
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.

HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
