Early outcomes after hip arthroscopy for femoroacetabular impingement in the athletic adolescent patient: a preliminary report.
BACKGROUND
Hip arthroscopy is becoming a more popular method of treatment of pediatric hip disorders. We report on the treatment of femoroacetabular impingement (FAI) in the adolescent population.


METHODS
Between March 2005 and May 2006, 16 patients (aged 16 years or younger) underwent hip arthroscopy for FAI. There were 14 female adolescents and 2 male adolescents, with 1 patient undergoing a bilateral procedure. Five patients had isolated pincer impingement, 2 had isolated cam impingement, and 9 had mixed pathology. All patients had labral pathology. Seven patients were treated with suture anchor repair of the labrum and 9 with partial labral debridement. Subjective data were collected from each patient during their initial visit and at follow-up after surgery. Subjective data included the modified Harris hip score (MHHS), patient satisfaction, and hip outcome score (HOS) activities of daily living (ADL), and sports subscales.


RESULTS
The mean age at the time of arthroscopy was 15 years old (range, 11-16 years). The mean preoperative MHHS was 55 (range, 33-70), HOS ADL was 58 (range, 38-75), and HOS sport was 33 (range, 0-78). The mean time from injury to surgery was 10.6 months (range, 6 weeks-30 months). The mean time to follow-up was 1.36 years (range, 1-2 years). The mean postoperative MHHS improved 35 points to 90 (range, 70-100; P = 0.005), postoperative HOS ADL improved 36 points to 94 (range, 74-100; P = 0.001), and postoperative HOS sport score improved 56 points to 89 (range, 58-100; P = 0.001). The mean patient satisfaction score was 9 (range, 9-10).


CONCLUSIONS
Hip arthroscopy for FAI in the adolescent population produces excellent improvement in function and a high level of patient satisfaction in the short-term.
