Obese patients undergoing total hip arthroplasty have been shown to have less functional recovery. This study prospectively compared temporal trends in patient-reported outcomes and activity levels between patients with a body mass index (BMI) of less than 30, 30 to 35, and 35 to 40 kg/m2 after total hip arthroplasty. Patients were evaluated via the Harris Hip Score, Lower Extremity Activity Scale, and Short Form-12 physical and mental components. The results suggest that patients with BMIs of 35 to 40 kg/m2 might have poorer functional outcomes preoperatively, with function returning more slowly or poor function being sustained and their not reaching other cohorts' levels. Surgeons must counsel these patients regarding functional expectations and the potential for slower functional returns.
