Arthroscopic capsular plication and labral preservation in borderline hip dysplasia: two-year clinical outcomes of a surgical approach to a challenging problem.

Abstract: The role of hip arthroscopy in the treatment of patients with dysplasia is unclear because of the spectrum of dysplasia that exists. Patients with borderline dysplasia are generally not candidates for periacetabular osteotomy because of the invasive nature of the procedure. However, arthroscopy in dysplasia has had mixed results and has the potential to exacerbate instability.

METHODS: Between April 2008 and November 2010, patients less than 40 years old who underwent hip arthroscopy for symptomatic intra-articular hip disorders, with a lateral center-edge (CE) angle ≥18° and ≤25°, were included in this study. Patients with Tönnis grade 2 or greater, severe hip dysplasia (CE ≤17°), and Legg-Calve-Perthes disease were excluded. Patient-reported outcome scores, including the modified Harris Hip Score (mHHS), Non-Arthritic Hip Score (NAHS), Hip Outcome Score-Sport-Specific Subscale (HOS-SSS), Hip Outcome Score-Activity of Daily Living (HOS-ADL), and visual analog scale (VAS) for pain were obtained in all patients preoperatively and at 1, 2, and 3 years postoperatively. Revision surgery and complications were recorded for each group.
