Extraction of implants due to periprosthetic infection (PJI) following complex revision total knee arthroplasty (rTKA) with extensive hardware can be a daunting undertaking for surgeon and patient alike. We question whether irrigation and debridement (I&D) has a role in this difficult situation with respect to infection control, reoperation, and function. rTKAs for PJI from 2005–2016 were reviewed. Extensive hardware was defined as: metaphyseal cone/sleeve fixation, distal femoral replacement, periprosthetic fracture hardware, or stems >75mm. Cases were categorized by treatment (I&D or 2-stage exchange).Introduction
