Hip arthroscopy in children and adolescents.
Hip arthroscopy has become an established procedure for certain indications in adults, but experience in children and adolescents has been more limited. The purpose of this study is to report the early-term results of hip arthroscopy in children and adolescents. A consecutive case series of 54 hip arthroscopies in 42 patients 18 years old and younger over a 3-year period at a tertiary-care children's hospital with a minimum of 1 year of follow-up was reviewed. Patients were assessed with the modified Harris hip score (HHS) before and after surgery. Overall results and results by common diagnoses were analyzed. Indications for surgery included isolated labral tear (n = 30), Perthes disease (n = 8), hip dysplasia with labral tear after prior periacetabular osteotomy (n = 8), inflammatory arthritis (n = 3), spondyloepiphyseal dysplasia (n = 2), avascular necrosis (n = 1), slipped capital femoral epiphysis (n = 1), and osteochondral fracture (n = 1). Overall, there was a significant improvement in HHS from 53.1 to 82.9 (P < 0.001), with 83% of patients improved. By diagnosis, significant improvement in HHS was seen for patients with isolated labral tears undergoing labral debridement (before surgery 57.6; after surgery 89.2; P < 0.001), for patients with Perthes disease undergoing chondroplasty and loose body excision (before surgery 49.5; after surgery 80.1; P < 0.001), and for patients with hip dysplasia after prior periacetabular osteotomy undergoing labral debridement (before surgery 51.8; after surgery 79.8; P < 0.001). Complications included transient pudendal nerve palsy (n = 3), instrument breakage (n = 1), and recurrent labral tear (n = 3). Hip arthroscopy in children and adolescents appears to be safe and efficacious for certain indications in the short term.
