Abstract
In summary we included all patients operated with AA, including the very first one. We found that there was increase in intraoperative blood loss, operation time, and more complications in the AA group without any improvement in hospital stay or early functional outcome. There was only a decreasing trend in the learning curve associated with the operating time, but there was no effect regarding the amount of blood loss intraoperatively or the length of hospital stay.
No significant quality outcome measure differences were identified between posterior and anterior THA surgical approaches in this prospective study suggests that surgical approach alone is not the grand solution to improved outcomes and decreased costs for elective THA. Other factors such as Physician-led, patient-focused care pathways to manage discharge disposition, care coordination throughout recovery, patient education, care specialized for surgical approach, and importance of rapid mobilization and early discharge home are important in effective care redesign resulting in improved patient outcomes and cost management. The current evidence does not support the recent enthusiasm for the use of the AA. It offers an intermuscular plane, but has a considerable learning curve.
