An unusual presentation of brucellar septic arthritis involving the knee joint with extraarticular hardware: a case report.

Brucellosis is a zoonotic infection with a wide spectrum of clinical presentations. We present a rare case of brucellosis with osteoarticular involvement complicated by a femoral intramedullary nail protruding the suprapatellar pouch. Although Brucella melitensis is a rare cause of brucellar septic arthritis, it should not be excluded from the list of suspected organisms in endemic areas for the disease.
