Failure of irrigation and débridement for early postoperative periprosthetic infection

Area of Science:

• Orthopedic Surgery
• Infectious Disease
• Biomedical Engineering

Background:

• Periprosthetic joint infection (PPI) treatment often involves irrigation and débridement (I&D).
• Existing literature shows variable infection control rates for I&D, ranging from 16% to 47%.
• The impact of intervention timing on I&D success for PPI remains unclear.

Purpose of the Study:

• To determine the failure rate of I&D performed within 90 days of primary surgery for PPI.
• To identify factors associated with I&D failure in the early postoperative period.

Main Methods:

• A multicenter retrospective analysis of 86 patients undergoing I&D for PPI within 90 days of primary surgery.
• Failure was defined as reoperation for infection-related issues.
• Analysis included assessment of covariates such as comorbidity index, age, sex, joint type, organism, and timing relative to primary surgery.

Main Results:

• The overall failure rate for I&D within 90 days was high, with 63% (54/86) of patients requiring further intervention.
• A significant proportion of failures occurred early: 80% within 10 days, 56% within 4 weeks, and 76% within 31-90 days.
• No investigated patient or procedural factors were significantly associated with increased odds of revision surgery for infection.

Conclusions:

• Irrigation and débridement (I&D) for periprosthetic joint infection (PPI) in the early postoperative period is frequently employed.
• Contrary to the assumption that early intervention improves outcomes, this study demonstrates a high failure rate for I&D within 90 days.
• The findings challenge the efficacy of early I&D as a standalone treatment for PPI, indicating a need for reassessment of treatment strategies.
