Weight and height separated provide better understanding than BMI on the risk of revision after total knee arthroplasty: report of 107228 primary total knee arthroplasties from the Swedish Knee Arthroplasty Register 2009–2017

摘要

Background and purpose — Obesity defined as increased BMI is commonly associated with higher revision rates following total knee arthroplasty (TKA). We examined the effect of BMI on the rate of revision after TKA, for both infection and other reasons, and analyzed weight and height separately to provide better understanding of the risk profile.
