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 (19.0–29.9 kg/m2 [reference], 30.0–34.9 kg/m2 [obese class I], 35.0 kg/m2+ [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.
