Stenotrophomonas maltophilia Periprosthetic Joint Infection after Hip Revision Arthroplasty.

Stenotrophomonas maltophilia , a well-established opportunistic bacterium, primarily impacts healthcare settings. Infection of the musculoskeletal system with this bacterium is rare. We report on the first known case of hip periprosthetic joint infection (PJI) caused by S. maltophilia . The potential for development of a PJI caused by this pathogen should be considered by orthopaedic surgeons, particularly in patients with multiple severe comorbidities.
