[Septic arthritis caused by erysipelotrix rhusiopathiae: case report and review of the literature]

Abstract

A 68-year-old man presented at our department with a suspected bacterial arthritis of the left knee. All diagnostic measures confirmed this diagnosis and the detected germ was Erysipelothrix rhusiopathiae. After arthroscopic debridement of the left knee, intravenous and oral antibiotic treatment for a total of 6 weeks, the patient was treated by total knee arthroplasty 6 months after the first presentation. The postoperative follow-up was without any pathological findings. There are only 4 other case reports in the international literature of Erysipelotrix rhusiopathiae linked to septic arthritis in humans. This case report of an infected knee further illustrates the pathogenicity of Erysipelothrix rhusiopathiae in humans.
