Revision Total Knee Arthroplasty (TKA) is becoming increasingly prevalent as the number of TKA procedures grow in a younger, higher-demand population. Factors associated with patients requiring multiple revision TKAs are not yet well understood. The purpose of this study is to investigate the epidemiology of re-revision TKA, and identify risk factors that are associated with failure of re-revision TKA. A retrospective analysis was performed on 358 patients who underwent revision TKA at a single institution between 1/2012 and 12/2013. Patients who underwent revision knee arthroplasty two or more times were included. Patients were excluded if their indication for the first revision was periprosthetic joint infection (PJI). Patient demographics, surgical indications, revision details, and available follow-up information were collected. Re-revision failure was defined as the need for any additional operative intervention. A logistic regression analysis was performed to assess for significant predictors of re-revision failure.Introduction

The epidemiology of re-revision total hip arthroplasty (THA) is not well understood. The purpose of this study is to investigate the epidemiology of re-revision THA, and identify risk factors that are associated with failure of re-revision THA. A retrospective analysis was performed on 288 patients who underwent revision THA at a single institution between 1/2012 and 12/2013. Patients who underwent revision hip arthroplasty two or more times were included. Patients were excluded if their indication for their first revision was due to periprosthetic joint infection (PJI). Patient demographics, surgical indications, revision details, and available follow-up information were collected through the electronic medical record. Re-revision failure was defined as the need for any additional return to the operating room, regardless of indication. A logistic regression analysis was performed to assess for significant predictors of re-revision failure.Introduction
