Morcos M, et al. - Authors compared the rate of 30-day major complications and hospital readmissions between patients undergoing simultaneous bilateral and unilateral total hip arthroplasty (THA) using the National Surgical Quality Improvement Program (NSQIP) database. Compared to the patients undergoing unilateral THA, the patients who had undergone simultaneous bilateral THA were more likely to be discharged to a rehabilitation facility and required significantly more perioperative transfusions, nonetheless, the likelihood of a 30-day major complication and readmission were similar between groups.
