Background Studies on 1-stage exchange in septic shoulder arthroplasty are limited and show a wide variation of treatment strategies. This retrospective study investigated infection-free survival and function of 1-stage exchange of septic shoulder arthroplasty following a standardized treatment algorithm. Methods The requirement for 1-stage exchange was an isolated microorganism from synovial fluid aspiration or synovial biopsy with an antibiotic susceptibility profile prior to revision surgery. If no microorganism was isolated or the underlying pathogen was a difficult-to-treat microorganism (not accessible for biofilm-active antibiotics, enterococci, and fungi), 2-stage exchange was performed. Function was assessed by the Constant score. Results Fourteen patients were included, with a mean follow-up period of 5.8 years. The most and second most commonly detected microorganisms were Cutibacterium acnes (formerly Propionibacterium acnes), and Staphylococcus epidermidis , respectively. At 1-stage exchange, patients received local and systemic antibiotics based on the susceptibility profile of the microorganism. Twelve patients with insufficient rotator cuffs received reverse shoulder arthroplasty, whereas 2 patients with intact rotator cuffs underwent anatomic total shoulder arthroplasty. The infection-free survival rate at 1 and 5 years was 100% and 93% (95% confidence interval [CI], 59%-99%), respectively, with 1 recurrence of infection 22 months after 1-stage exchange. Another patient with limited range of motion underwent revision 6 months postoperatively, leading to a revision-free survival rate of 93% (95% CI, 59%-99%) and 86% (95% CI, 54%-96%) at 1 and 5 years, respectively. The mean Constant score was 65 (range, 44-95). Conclusion One-stage exchange with prior detection of the underlying microorganism provides satisfactory infection-free survival and function.
