[Infection of a total knee prosthesis with Brucella spp]

Abstract

Brucellosis, an "anthropophitic" disease of worldwide distribution can involve several organs and tissues but the osteoarticular disease is the most common complication. It can occur as sacroiliitis, bursitis, tenosynovitis or osteomyelitis. Prosthetic joint infection is a serious complication of total joint arthroplasty, with coagulase negative staphylococci and Staphylococcus aureus accounting for 50% of cases. Treatment of prosthetic infections remains complex. Prosthetic infections caused by Brucella spp are rarely described in the literature. We report a patient with a prosthetic joint infection due to Brucella spp, documented by a polymerase chain reaction. The patient has been cured after two-stage exchange of the prosthesis and long-term antimicrobial therapy.
