Abstract
BackgroundWe sought to evaluate reoperation-free survival following I&D with modular component exchange of revision total joint arthroplasty (TJA). MethodsOf revision TJAs from 2004 to 2012 (n = 4,166), 30 were I&D with modular component exchange after index revision for aseptic indications. Patients with (n = 12) and without (n = 18) reoperation for infection recurrence were analyzed. ResultsReoperation-free survival (60% at mean 4.8 year follow-up) improved with increased duration of antibiotic therapy (p = 0.0185), with maximum benefit at 2 years. ConclusionsAt least 2 years of antibiotic therapy should be administered after I&D with modular component exchange for acutely infected revision TJA. Level of evidenceLevel III, retrospective comparative study.
