Fungal Prosthetic Joint Infection: A Case Series and Review of the Literature

Abstract

Abstract Introduction Fungal prosthetic joint infections comprise less than 1% of prosthetic joint infections. Thus, little is known regarding optimal management. This study aims to characterize the microbiology, surgical and medical management, and outcomes for these complex infections. The objectives of this study were to assess the impact of surgical approach, antifungal treatment, fungal species, and time to onset of infection from initial surgery on patient outcomes. Methods A retrospective record review over 12 years was performed in two health systems that included patients with a deep culture positive for a fungal isolate and the presence of a prosthetic joint. A literature review was performed using the same inclusion criteria. A total of 289 cases were identified and analyzed. Results Candida was the most common isolate, and a two-stage revision was the most commonly employed surgical modality. The type of surgical intervention had a statistically significant relationship with outcome (P = 0.022). Conclusions Two-stage revision with extended antifungal therapy is preferred in these infections due to higher rates of positive outcomes.
