Salmonella prosthetic joint septic arthritis

We describe a case of Salmonella enteritidis infection of a prosthetic knee joint that was cured with ceftriaxone therapy for 6 weeks and replacement of the tibial component of the prosthesis. Eleven other cases of salmonella prosthetic joint infection have been reported in the English-language literature. Five infections occurred within 20 days of prosthesis placement, and seven occurred several months to years later; ten of 12 infections involved hip prostheses. Nine of 12 patients who had prosthesis removal were cured of the infection. Two of the three patients with retention of the prosthesis required long-term suppressive antibiotic therapy
