Abstract
OBJECTIVE: Utilize a nationwide database to identify and compare the differences between patient demographics and clinical outcomes for patients undergoing simultaneous bilateral total hip arthroplasty (THA) and unilateral THA. METHODS: A nationwide administrative claims database was utilized; In-hospital, 90-day, and 1-year post-discharge rates of local and systemic complications were collected and compared with multivariate logistic regression. RESULTS: Incidence of prosthetic joint infection was significantly lower in the bilateral cohort. Length of stay was significantly shorter in the unilateral THA cohort. CONCLUSION: Surgeons should consider simultaneous bilateral THA a safe and effective procedure for low risk patients with appropriate comorbidities.
