Arthroscopic Treatment of Hip Pain in Adolescent Patients With Borderline Dysplasia of the Hip: Minimum 2-Year Follow-Up.
To examine arthroscopic treatment of hip pain in patients with borderline hip dysplasia (lateral center edge angle [LCEA] between 20° and 25°).
From 2008 to 2013, patients below 18 years of age who underwent arthroscopic hip surgery with an LCEA between 20° and 25° were retrospectively matched 1:1 to a control group without dysplasia (LCEA ≥25°) based on age, gender, femoroplasty, labral treatment, and capsular plication. Indications for surgery included failure to improve with nonoperative treatments and anti-inflammatory medications after 3 months. Patient-reported outcome data were collected using modified Harris hip score, hip outcome score-activities of daily living subscale, hip outcome score-sports-specific subscale, nonarthritic athletic hip score, and visual analog scale.
