Two-stage exchange arthroplasty remains the gold standard for treatment of PJI with reported success rates of 85–90%. Complications that occur during treatment are often not reported or considered in the success rate. The purpose of this study was to analyze complications in patients undergoing two-stage exchange and determine when they occur. We analyzed all patients that underwent two-stage exchange arthroplasty for treatment of chronic PJI of the knee from 2010 to 2018. We categorized complications as medical vs. surgical. The intervals for complications were divided into: interstage, early post re-implant (3 months) and late post re-implant (3 months to minimum 1 year). Minimum follow-up to evaluate complications was one year.Introduction

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
