Abstract

Influence of BMI upon patient outcomes and complications following THA was examined across a national cohort of patients. Outcomes were compared by BMI groups (19.0-29.9kg/m(2) [reference], 30.0-34.9kg/m(2) [obese class I], 35.0kg/m(2)+ [obese class II/III]), adjusted for case-mix differences. Obese class I patients had a significantly smaller improvement in OHS (18.9 versus 20.5, P<0.001) and a greater risk of wound complications (odds ratio [OR]=1.57, P=0.006). For obese class II/III patients, there were significantly smaller improvements in OHS and EQ-5D index (P<0.001), and greater risk of wound complications (P=0.006), readmission (P=0.001) and reoperation (P=0.003). Large improvements in patient outcomes were seen irrespective of BMI, although improvements were marginally smaller and complication rates higher in obese patients.
