Culture-negative periprosthetic joint infections: Do we have an issue?

Area of Science:

• Orthopedics
• Infectious Diseases
• Medical Microbiology

Background:

• Culture-negative periprosthetic joint infection (PJI) presents diagnostic and therapeutic challenges.
• Uncertainty in pathogen identification impacts antimicrobial treatment selection and patient outcomes.
• Advances in molecular diagnostics offer potential solutions for culture-negative PJI.

Purpose of the Study:

• To review the incidence, risk factors, and optimal treatment for culture-negative PJI.
• To compare outcomes between culture-positive and culture-negative PJI.
• To explore the role of novel molecular diagnostic methods in managing culture-negative PJI.

Main Methods:

• Narrative review of current literature.
• Discussion of antimicrobial therapy and treatment duration.
• Evaluation of molecular diagnostic techniques for pathogen identification.

Main Results:

• Culture-negative PJI has specific incidence and risk factors.
• Optimal antimicrobial strategies and treatment durations are discussed.
• Molecular methods show promise for pathogen detection in culture-negative cases.

Conclusions:

• Molecular diagnostics are crucial for identifying pathogens in culture-negative PJI.
• Accurate pathogen identification enables targeted antimicrobial therapy.
• Implementing molecular diagnostics supports antibiotic stewardship programs for PJI.
