There are many young patients with hip pain of unknown origin. We have performed hip arthroscopy in nine patients. Under epidural anesthesia, patients are placed in a supine position on the traction table, and the hip joint is abducted slightly and pulled distally. After injecting physiologic saline into the joint, the arthroscope (Storz ∅5mm, 0°, 30°, 70°, 120° degrees) is inserted from just proximal to the greater trochanter with the aid of the image intensifier. In 6 cases, we found acetabular labral tears in posterosuperior portion, which seemed to be the cause of the hip pain. They had pain both with passive flexion and with passive internal rotation of the hip joint in physical examination. In one case, many cartilagenous loose bodies were found in the acetabular fossa, which enabled us to make a diagnosis of synovial chondromatosis. Accordingly, the hip arthroscopy can clarify thecause of hip pain in such young patients whose X-ray findings are normal.
