Total hip arthroplasty (THA) using the direct anterior approach (DAA) is undertaken with the patient in the supine position, creating an opportunity to replace both hips under one anaesthetic. Few studies have reported simultaneous bilateral DAA-THA. The aim of this study was to characterize a cohort of patients selected for this technique by a single, high-volume arthroplasty surgeon and to investigate their early postoperative clinical outcomes. Using an institutional database, we reviewed 643 patients who underwent bilateral DAA-THA by a single surgeon between 1 January 2010 and 31 December 2018. The demographic characteristics of the 256 patients (39.8%) who underwent simultaneous bilateral DAA-THA were compared with the 387 patients (60.2%) who underwent staged THA during the same period of time. We then reviewed the length of stay, rate of discharge home, 90-day complications, and readmissions for the simultaneous bilateral group.Aims
Methods
Direct anterior approach (DAA), total hip arthroplasty (THA, performed with the patient in the supine position, creates a unique opportunity to do bilateral THA under one anesthesia. Previous studies evaluating this option are limited by small sample size or lack of control group. The purpose of this study is to compare early clinical outcomes of simultaneous bilateral, unilateral and staged bilateral DAA-THA. Using an institutional registry database, we reviewed 3977 DAA-THA performed in 3334 patients at minimum 90-days follow up. A single surgeon performed all surgeries. Simultaneous bilateral DAA-THA group included 512 hips in 256 patients, unilateral DAA-THA group 2691 hips and staged bilateral DAA-THA group 774 hips in 387 patients. We reviewed 90-day postoperative complications, readmissions, length of stay, and rate of home discharge between all three groups.Background
