Editorial Commentary: In Patients Undergoing Periacetabular Osteotomy for Hip Dysplasia, Whether Combined or Staged, the Labrum Should Be Arthroscopically Repaired.

Periacetabular osteotomy (PAO) is the gold standard procedure for patients with significant hip dysplasia. Hip arthroscopy is the gold standard procedure for repairing labral tears. In the past, open PAO procedures were performed without any concomitant labral repair surgery with successful outcomes. Nevertheless, with advances in hip arthroscopy, better outcomes can be achieved by repairing the labrum, as well as performing PAO to achieve bony correction of the deformity. Whether staged or combined, hip arthroscopy plus PAO most successfully treats hip dysplasia. Fix the bony deformity, but also fix the structural damage. Repairing the labrum, combined with PAO, will lead to better outcomes.
