A rare case of Staphylococcus caprae–infected total hip arthroplasty: a report and literature review

We report a rare case of Staphylococcus caprae hip arthroplasty infection. To be best of our knowledge, this is the 38th case of S. caprae prosthetic joint infection and the 9th case of S. caprae hip arthroplasty infection to be reported in the medical literature. The case was successfully treated by minor partial one-stage revision and culture-directed antibiotic therapy. Clinicians must maintain a low index of suspicion for S. caprae as a pathogen in orthopedic infections. We suggest that a minor partial one-stage revision is appropriate treatment because it balances low morbidity with good functional outcomes and a low chance of re-revision for infection at two years. We propose the following as markers of therapeutic success: (1) early detection of infection, (2) absence of radiolucent lines around the bone–prosthesis interface on plain radiographs, (3) monomicrobial infection, (4) infection with an organism of low virulence, (5) culture-proven susceptibility to available antibiotics, and (6) immunosuppression that is effectively treatable.
