Arthroplasty Infection by Priopionibacterium granulosum Treated With Reimplantation Despite Ongoing Purulent-Appearing Fluid Collection
Department of Orthopaedics & Rehabilitation, University of Iowa Hospitals & Clinics, Iowa City, Iowa.The Journal of arthroplasty (Impact Factor: 2.67). 04/2012; 28(1). DOI: 10.1016/j.arth.2012.03.004
We present the first case of infection in a native or prosthetic joint by Propionibacterium granulosum in which a patient developed symptoms of prosthetic hip infection 5 years after primary surgery. The patient required multiple operative debridements to eradicate the infection and was successfully reimplanted despite an ongoing purulent-appearing, although sterile, fluid collection at the time of reimplantation. There is no clinical or laboratory evidence of infection at 3 years post-reimplantation, and the patient has a well-functioning total hip arthroplasty. P granulosum is a low-virulence but highly-inflammatory organism. It seems to produce a large fluid collection that may require multiple debridements. To our knowledge, there are no reported cases of native or prosthetic joint infection from P granulosum. We present the first case here.
