Concomitant infections of several prostheses are very rare, serious events that pose particular medical and surgical therapeutic challenges. This study was undertaken to describe epidemiologic, clinical, and microbiological characteristics of concomitant multiple joint arthroplasty infections, their treatments, and outcomes.
Retrospective (January 2000 and January 2014), single-center, cohort study in a referral center for bone and joint infections. All patients with at least 2 concomitant, microbiologically documented, prosthetic joint infections, that is, during the same septic episode, were included.
Sixteen patients were included. Median (range) age was 78 years (46-93 years), gender ratio was 1, and median (range) body mass index was 27 (21-42). Multiple joint arthroplasties (bilateral hip in 8 patients; bilateral knee in 3 patients; hip and knee in 1 patient; and 2 knees and 1 hip in 1 patient) were contaminated hematogenously in all patients, 2 after early postoperative infections. Eight Staphylococcus aureus, 1 Staphylococcus epidermidis, 6 Streptococcus, and 1 Escherichia coli strains were isolated. A curative strategy was applied to 11 patients: 3 underwent bilateral synovectomies, 6 had successive 1-stage exchange arthroplasties, and 2 were treated with other strategies. After 37 months (range, 24-132 months) of follow-up, reinfection occurred in 1 patient. The 5 other patients received prolonged suppressive antibiotic therapy.
These complex infections occur during staphylococcal or streptococcal bacteremia. Treatment strategies should be discussed by a multidisciplinary team on a case-by-case basis.
