The influence of obesity on achievement of a ‘forgotten joint’ following total knee arthroplasty

Introduction Obesity has been associated with poorer outcomes following total knee arthroplasty (TKA); however, data remain sparse on its impact on patients’ joint awareness following surgery. This study aims to investigate the impact of body mass index (BMI) on improvement in outcomes following TKA...

Description
Summary:Introduction Obesity has been associated with poorer outcomes following total knee arthroplasty (TKA); however, data remain sparse on its impact on patients’ joint awareness following surgery. This study aims to investigate the impact of body mass index (BMI) on improvement in outcomes following TKA as assessed by the Forgotten Joint Score-12 (FJS-12). Materials and methods We retrospectively reviewed 1075 patients who underwent primary TKA from 2017 to 2020 with available postoperative FJS-12 scores. Patients were stratified based on their BMI (kg/m 2 ):
