Defining peri-prosthetic infection: do we have a workable gold standard?

Area of Science:

• Orthopedics
• Infectious Diseases
• Medical Diagnostics

Background:

• Peri-prosthetic infection is a significant complication following joint replacement surgery.
• It is a primary indication for revision arthroplasty, impacting patient outcomes.
• Current diagnostic criteria are based on clinical and laboratory findings.

Purpose of the Study:

• To evaluate the limitations of existing definitions for peri-prosthetic infection.
• To propose an alternative definition that better addresses clinical uncertainties.
• To improve the diagnostic accuracy and management of peri-prosthetic infections.

Main Methods:

• Review of recent publications and guidelines from the American Musculoskeletal Infection Society.
• Critical analysis of the established definition of peri-prosthetic infection.
• Development of a proposed alternative definition based on clinical experience.

Main Results:

• The current definition based on clinical findings and laboratory investigations has limitations.
• The proposed alternative definition aims to enhance diagnostic precision.
• The revised approach may better represent the complexities of peri-prosthetic infection in clinical settings.

Conclusions:

• Existing definitions for peri-prosthetic infection may not fully capture clinical realities.
• An alternative definition is proposed to improve diagnostic clarity.
• This revised approach could lead to more effective management strategies for these challenging infections.
