The purpose of this study was to compare the clinical outcomes and complications following bilateral simultaneous total knee arthroplasty in high body mass index (BMI) patients(>30kg/m2) to those of patients with a BMI<30 kg/m2. Using data from an academic arthroplasty database and review of clinic charts we obtained health related quality of life (SF-12), and disease specific functional outcome scores (WOMAC or Oxford Knee Score). We also assessed length of hospital stay, ASA grade and transfusion requirements. Sixty six patients had a BMI<30 and 151 patients had a BMI>30.Introduction
