PG - 2473-2484 LID - S0749-8063(21)00257-7 [pii] LID - 10.1016/j.arthro.2021.03.034 [doi] AB - PURPOSES: To report minimum 2-year follow-up patient-reported outcome scores (PROs) in borderline dysplastic female patients who underwent primary hip arthroscopy with femoroplasty, labral repair, iliopsoas fractional lengthening, and plication of the capsule (FLIP procedure) for cam-type femoroacetabular impingement syndrome (FAIS), labral tear, and painful internal snapping and to compare these PROs to a propensity-matched borderline dysplastic control group without painful internal snapping. METHODS: Data were retrospectively reviewed for patients who underwent primary hip arthroscopy for cam-type FAIS and labral tear between September 2008 and May 2017.
