Mycobacterium bovis infection of total hip arthroplasty after intravesicular Bacillus Calmette-Guérin

Intravesicular application of Bacillus Calmette-Guérin (BCG), a live attenuated strain of Mycobacterium bovis, is effective in the treatment of bladder cancer. However, systemic dissemination and subsequent infection of implants have been reported. We present a case of M. bovis infection of a total hip arthroplasty 5 years after BCG instillation for bladder cancer. He was treated with debridement, antibiotics, irrigation, and prosthesis retention with appropriate antituberculous therapy. At 4 years after surgery and 3 years after cessation of treatment, he has had no recurrence of infection with a good functional outcome. This case highlights the need to consider Mycobacteria infection in patients who have received intravesicular BCG. Debridement and retention of well-fixed implants can be successful in combination with appropriate antituberculous therapy.
