No influence of obesity on survival of cementless, posterior-stabilised, rotating-platform implants

Introduction This study compares survival and outcomes in four total knee arthroplasty (TKA) populations defined by baseline body mass index (BMI). We hypothesised that there would be no difference in survival between the groups. Materials and methods Using an initial cohort of 1059 TKAs, BMI was sy...

Zusammenfassung:	Introduction This study compares survival and outcomes in four total knee arthroplasty (TKA) populations defined by baseline body mass index (BMI). We hypothesised that there would be no difference in survival between the groups. Materials and methods Using an initial cohort of 1059 TKAs, BMI was systematically measured prior to surgery. A retrospective study was conducted and patients were accordingly allocated to four groups: normal or underweight (BMI
