Polymicrobial Infection Is Associated with Failure of DAIR in Acute Hip Periprosthetic Joint Infection

Key Points

To evaluate the association between polymicrobial infection and treatment failure in acute hip periprosthetic joint infections (PJIs).
Analyzed outcomes of DAIR treatment in patients with acute hip PJIs.
Exploratory risk stratification models were proposed for preoperative assessment.
Polymicrobial infections were linked to higher rates of treatment failure.
Findings suggest a need for alternative surgical strategies for these cases.

Abstract

DAIR is an effective treatment option for selected patients with acute hip PJI. Polymicrobial infection was associated with treatment failure and should prompt careful consideration of alternative surgical strategies. Exploratory risk stratification models may assist in preoperative decision-making; however, validation in larger cohorts is required.
