title: Hematogenously acquired infection of a total knee arthroplasty by Clostridium perfringens.
abstract: A 64-year-old man with total knee arthroplasty for tricompartmental osteoarthritis had a postoperative course complicated by an attack of acute cholecystitis and was treated with cholecystectomy. The TKA was hematogenously seeded with Clostridium perfringens, which necessitated emergency removal of the implants, debridement, and ultimately arthrodesis.
