Abstract

Brucella infection associated with arthroplasty is a rare event. An unspecific clinical symptomatology is associated with unclear radiographic signs of periprosthetic bone halisteresis. Only a positive anamnesis combined with an antibiogram of the joint liquid and a high serum antibody titer can lead to a definitive diagnosis. We herein report a case of Brucella melitensis infection in a patient who underwent total knee arthroplasty 2 years earlier. Plain radiography and bone scintigraphy confirmed septic loosening. The patient was successfully treated with two-stage revision arthroplasty.
