Predictors of Outcomes in Candida Prosthetic Joint Infections: Review and Meta-Analysis
Overview
This systematic review and meta-analysis of 385 Candida prosthetic joint infections (CPJI) identified key predictors of treatment outcomes. Complete prosthesis removal and first-line amphotericin B therapy were associated with higher success rates, while co-infection with Staphylococcus aureus and prosthesis retention predicted failure.
Background
Prosthetic joint infections (PJI) complicate 1%–2% of total hip or knee arthroplasties, with fungi accounting for 1%–3% of cases, predominantly Candida species. CPJI often occur in patients with comorbidities and prior antibiotic exposure, posing treatment challenges due to biofilm formation and limited antifungal options. Optimal surgical and antifungal management strategies remain unclear, with current guidelines based largely on expert opinion rather than robust evidence.

Predictor of success (OR, 95% CI)
First-line amphotericin B therapy (3.18; 1.25–9.87)
Effect of prosthesis exchange type
No significant difference (1-, 2-, or 3-stage)
Effect of local antifungal therapy
No significant impact on outcome
Key Findings
Complete hardware removal is crucial for successful treatment of CPJI.
Co-infection with Staphylococcus aureus significantly predicts treatment failure.
Debridement with retention of the prosthesis is associated with poorer outcomes.
First-line antifungal therapy with amphotericin B significantly improves success rates.
No significant outcome differences were observed between 1-, 2-, or 3-stage prosthesis exchange procedures.
Use of local antifungal therapy, such as antifungal-impregnated spacers, does not significantly affect outcomes.
Clinical Implications
Clinicians should prioritize complete removal of infected prosthetic material in CPJI management to optimize outcomes. Amphotericin B should be considered as the initial systemic antifungal therapy given its association with higher success rates. The choice of prosthesis exchange strategy can be flexible, as no significant differences in outcomes were found among different staged procedures.
Conclusion
This comprehensive review confirms the importance of complete prosthesis removal and supports amphotericin B as first-line antifungal therapy in Candida prosthetic joint infections. These findings provide evidence-based guidance to improve management strategies in this challenging clinical scenario.
