Abstract
BACKGROUND: The purpose of this study was to examine intraarticular pathology in patients younger than 20 years with symptomatic developmental dysplasia of the hip. METHODS: We performed hip arthroscopy during corrective osteotomy in 23 hips in 22 patients. All patients were female, and the average age at operation was 16.4 years. Eighteen hips were in a prearthritic stage, and 5 hips were in an early stage. The presence and location of cartilage degeneration and labral tears were evaluated. Second-look arthroscopy was performed in 13 hips in 12 patients. RESULTS: Fourteen hips (77.8%) in the prearthritic stage had cartilage degeneration. Cartilage lesions were more frequent in the acetabulum than in the femoral head (72.2% vs 16.7%). Sixty-one percent of acetabular lesions were located at the anterosuperior area. Labral tears were observed in 77.8% of hips in prearthritic stages located at the anterosuperior (72.2%) and superior (44.4%) areas. The degree of cartilage and labral lesions in the early stage was more severe than in the prearthritic stage. On second-look arthroscopy, there were no changes in the state of the cartilage and labrum in the majority (84.6%) of hips. CONCLUSIONS: The incidence of intraarticular lesions in developmental dysplasia of the hip was high, even in the prearthritic stage. These lesions tended to originate in the anterosuperior area of the acetabulum and were generally progressive. LEVEL OF EVIDENCE: Therapeutic study, level IV.
