Concerns remain with regards to safety of fast-track (FT) and especially outpatient procedures. The purpose of this study was to compare complication rates and clinical outcomes of propensity-matched patients who received FT total hip arthroplasty (THA) in outpatient versus inpatient settings. The hypothesis was that 90-day postoperative complication rates of outpatient FT THA would not be higher than after inpatient FT THA. This is a prospective study of consecutive patients who received FT THA at various rates of outpatient and inpatient surgery by 10 senior surgeons (10 centres). The decision between outpatient and inpatient surgery was made on a case-by-case basis depending on the surgeon and patient. All patients were followed until 90 days after surgery. Complications, readmissions and reoperations were collected, and their severity was assessed according to Clavien-Dindo. Patients completed Oxford Hip Score (OHS) at the latest follow-up. Compared to inpatient FT THA, patients scheduled for outpatient FT THA had no significant differences in 90-day postoperative complication rates (10.7% vs. 12.9%,  = 0.129). There were no significant differences between the 2 groups in 90-day readmission rates and reoperation rates, in severity of postoperative complications, and in time of occurrence of postoperative complications. There were no differences in rates of intraoperative complications, 90-day postoperative complications, readmissions, or reoperations between outpatient and inpatient FT THA. These findings may help hesitant surgeons to move towards outpatient THA pathways as there is no greater risk of early postoperative complications that could be more difficult to manage after discharge.
