Background : The indications for hip arthroscopy continue to evolve. This study investigated the results of arthroscopic surgery for symptomatic hip joint diseases.
Patients and methods : Nine patients were included in this study. The etiology was femoroacetabular impingement in 3 hips, dysplasia in 2 hips, ossification of the labrum in 1 hip, Perthes disease in 1 hip, labrum tear in 1 hip, and septic arthritis of the hip in 1 hip. Chondral lesions were classified using the International Cartilage Research Society classification system.
Results : Labral debridement for degenerative tear or ossification was performed in 6 hips and labral repair was performed for 2 hips. Femoral head-neck osteoplasty was performed for 6 hips. Microfracture was performed for 1 dysplastic hip with grade 4 chondral lesions. The mean Japanese Orthopaedic Association hip score was improved from 58 points preoperatively to 81 points at follow-up. However, pain remained in 3 hips that had grade 3 or 4 chondral lesions.
Conclusion : Hip arthroscopy is a useful surgical technique for hip joint diseases. However, its indications for dysplastic cases require circumspection.
