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 Delta physical component summary, Delta mental component summary, and Delta Western 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.en-USAdultAgedAged, 80 and over*Arthroplasty, Replacement, Hip*Arthroplasty, Replacement, KneeBody Mass IndexFemaleHumansMaleMiddle Aged*ObesityPatient SatisfactionQuestionnairesTreatment OutcomeHealth Services ResearchOrthopedicsJournal Articlehttps://escholarship.umassmed.edu/cor_hipknee/22328949cor_hipknee/2
