Brucella melitensis infection in total knee arthroplasty: a case report.

We report a case of a 63-year-old female patient who underwent a total knee arthroplasty in which the knee later became infected with Brucella melitensis. Diagnosis was made by positive culture of a sinus tract discharge. Radiological views of the knee did not show signs of implant loosening. The patient was successfully treated with rifampicin and doxycycline without surgery.
