Results of a matched-cohort study at minimum two year follow-up. PG - 2567-2575 LID - 10.1007/s00264-020-04810-8 [doi] AB - PURPOSE: The purpose of this study was to assess intra-operative findings, surgical procedures, and outcomes in a cohort of patients with borderline hip dysplasia treated with arthroscopic labral repair, femoral osteoplasty, and capsular plication, and compare these outcomes with those of a rigorously matched control group without dysplasia. METHODS: Data were prospectively collected and retrospectively reviewed for patients with a lateral center-edge angle between 20 and 24 degrees who underwent hip arthroscopy surgery between 2014 and 2018. Labral, chondral status, psoas impingement, ligamentum teres, and cam morphology were evaluated. Patient-reported outcomes (PROs) scores included modified Harris Hip Score (mHHS), Hip Outcome Score Activities of Daily Living Subscale (HOS-AVD) and Hip Outcome Score Sport-Specific Subscale (HOS-SSS), and International Hip Outcome Tool-12 (IHOT-12). Clinical relevance was measured with the minimal clinical important difference (MCID), patient acceptable symptom state (PASS), and substantial clinical benefit (SCB). RESULTS: Twenty patients met the inclusion criteria. An age- and sex-matched control group of 40 patients was also selected. Arthroscopic intra-operative findings were similar between cohorts. At a mean follow-up of 50 months in the borderline hip dysplasia cohort, and 52 months in the control cohort, there was a significant improvement in PROs in both cohorts, and no significant differences could be detected at the latest follow-up. The difference in frequency of patients achieving the MCID, PASS, and SCB was not statistically significant between cohorts. CONCLUSION: With strict patient selection criteria, hip arthroscopy may be a beneficial approach in patients with borderline hip dysplasia.
