Abstract
Purpose: The number of obese patients seeking total hip arthroplasty (THA) continues to expand despite body mass index (BMI) cutoffs. We sought to determine the outcomes of THA in the morbidly obese patient, and hypothesized they would have comparable outcomes to two cohorts of obese, and normal weight patients. Materials and Methods: . Acute postoperative outcomes and BMI change after surgery were evaluated for clinical significance with univariate and regression analyses. Cox proportional hazard ratio was calculated to evaluate prosthetic joint infection (PJI) and revision surgery through follow-up. Mean follow-up was 3.9 years. Results: as a reference demonstrated no significant difference in survival to PJI and all-cause revision in the morbidly obese cohort. Conclusion: ) in terms of PJI or all-cause revisions at mid-term follow-up.
