“…Proposed advantages include a theoretical benefit of a single operative event, cost savings (1–4), shorter total postoperative hospitalisation, (2–6) and decreased time to maximal functional outcome (7). Possible disadvantages include prolonged operative duration (2, 5, 6, 8), increased estimated blood loss (EBL) and need for blood transfusion (2, 3, 5, 6, 9, 10), increased rates of venous thromboembolic events (VTE) (10, 11), higher utilisation of inpatient rehabilitation services (6, 9), increased rates of subsequent and revision hip surgeries (3), and decreased reimbursement rates (1). Published reports are inconsistent regarding these claims and include surgical approaches performed in the lateral decubitus position that require repositioning the patient, repeat prepping and draping, and exposure of the fresh surgical wound to pressure and manipulation while performing the contralateral THA.…”
