    PurposesTo 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.MethodsData were retrospectively reviewed for patients who underwent primary hip arthroscopy for cam-type FAIS and labral tear between September 2008 and May 2017. Females with borderline dysplasia (lateral center-edge angle of ≥18° to ≤25°) and painful internal snapping, who underwent the FLIP procedure, with minimum 2-year PROs for modified Harris Hip Score, Nonarthritic Hip Score, Hip Outcome Score-Sports-Specific Subscale, patient satisfaction, and visual analog scale (VAS) for pain were included. The group was matched 1:1 to a control group without painful internal snapping for age, sex, body-mass index (BMI), and surgical procedures. The minimal clinically important difference (MCID) was calculated. P-value was set at .05.ResultsSeventy-four hips were included. The mean was 26.82 ± 10.49 years and 23.62 ± 4.56 kg/m2 for age and BMI, respectively. Improvement was reported for all PROs and VAS (P < .0001). Twenty-nine patients were matched. At minimum 2-year follow-up, the FLIP procedure demonstrated comparable improvement in PROs and rate of achievement of MCID to the control group.ConclusionAfter primary hip arthroscopy and FLIP procedure, females with borderline dysplasia and painful internal snapping demonstrated significant improvement in PROs at minimum 2 years' follow-up. When compared to a propensity-matched control group without painful internal snapping, the improvement between groups was comparable.Level Of EvidenceIII; Case-Control study.Copyright © 2021 Arthroscopy Association of North America.
