Arthroscopy of the hip in children and adolescents.

Intra-articular abnormalities of the hip, such as labral tears, loose bodies, chondral lesions, ligamentum teres tears and femoral acetabular impingement are increasingly being recognized in the pediatric age group. Evaluation for these abnormalities starts with a good history and physical exam. Radiographic imaging with plain films and magnetic resonance imaging help confirm the clinical impression. Arthroscopy of the hip can be utilized to diagnose and treat these abnormalities. Arthroscopy of the hip is a challenging procedure with a learning curve that requires a thorough knowledge of the anatomy of the hip. The hip is a deeply recessed joint that has a large muscular envelope, thick joint capsule and convex and concave surfaces of the femoral head and acetabulum, respectively. The normal anatomy may be distorted due to childhood developmental disorders such as hip dysplasia, Legg-Calve-Perthes Disease and Slipped Capital Femoral Epiphysis that adds additional challenges to the arthroscopist. Isolated intra-articular abnormalities occur rarely and an underlying morphologic abnormality should be identified which also requires management. Complications can be minimized with attention to detail.
