Objective: The purpose of this study was to examine the relationship between obesity and patient-administered outcome measures after total joint arthroplasty.
Research Methods and Procedures: A voluntary questionnaire-based registry contained 592 primary total hip arthroplasty patients and 1011 primary total knee arthroplasty patients with preoperative and 1-year data. Using logistic regression, the relationships between body mass index and the several outcome measures, including Short Form-36 and Western Ontario and McMaster Universities Osteoarthritis Index, were examined.
Results: There was no difference between obese and non-obese patients regarding satisfaction, decision to repeat surgery, and Δphysical component summary, Δmental component summary, and ΔWestern Ontario and McMaster Universities Osteoarthritis Index scores (p > 0.05 for all). Body mass index was associated with an increased risk of having difficulty descending or ascending stairs at 1 year (odds ratio, 1.2 to 1.3).
Discussion: Obese patients enjoy as much improvement and satisfaction as other patients from total joint arthroplasty.
