Nineteen patients with Perthes' disease treated conservatively and eleven patients with osteoarthritic changes after Perthes' disease were evaluated clinicaly and radiologicaly at the age of fifteen years old. The clinical results were good. The radiological results at the follow-up period depended on the Catterall's group, the head at risk sign, and the maladaptation between femoral head and acetabulum. In conclusion acetabular roof angle on poor result cases was especialy steep, and subluxation of the femoral head at the first stage was the most critical cause of osteoarthritis.
