Outcomes of Total Knee Arthroplasty Revisions in Obese and Morbidly Obese Patient Populations.

Background: The obese population is at higher risk for complications following primary total knee arthroplasty (TKA), but little data is available regarding revision outcomes. This study aimed to investigate the role of body mass index (BMI) in the cause for revision TKA and whether BMI classification is predictive of outcomes.

Methods: A multi-institutional database was generated, including revision TKAs from 2012 to 2019.
