A rare case of prosthetic joint infection caused by group D Salmonella

Prosthetic joint infections (PJIs) are gaining growing attention as a health-care issue. Salmonella spp. is a rare cause of PJI, mostly involving hip-arthroplasty rather than knee arthroplasty. Therefore, indications for the best management of PJI involving knee-arthroplasties caused by Salmonella spp. are not clear. We report a case of knee-PJI caused by group D Salmonella , successfully treated with a two-stage revision surgery and appropriate antibiotic therapy, based on antimicrobial susceptibility of the cultural isolate. Such challenging cases evidence that clinical success is achievable through appropriate medical and surgical management, combined with a strong collaboration between orthopedics and infectious disease specialists.
