The Bernese periacetabular osteotomy has been performed at Children's Hospital Boston since 1991 for correction of dysplastic hips. We are currently in the process of obtaining radiographic and clinical long-term follow-up data in order to determine the effectiveness of this procedure in halting or preventing the development of osteoarthritis of the hip.

In early osteoarthritis, the charge extracellular matrix is degraded and lost. The delayed gadolinium enhanced MRI of cartilage technique is designed to indirectly measure the early loss of charge density in cartilage.

Legg-Calve-Perthes disease has an outcome that can vary depending on the amount of femoral head involvement. Currently, much of our early treatment goal is geared towards keeping the femoral head round. Unfortunately, we can only determine which hip will require treatment only when the femoral head collapse begins. Therefore, an early measure of femoral head involvement before collapse is thought to be very useful in selecting hips that need treatment and may make current treatment more effective. Future medical therapies that may prevent femoral head collapse without surgery will depend on an early staging method due to the variable nature of this disease.
