The outcome of joint-preserving procedures for the treatment of hip osteonecrosis1,2 and acetabular dysplasia3 has been related to the quality of the acetabular cartilage at the time of the operative intervention4-7. An ability to evaluate the condition of the acetabular cartilage prior to surgical intervention could improve the predictability of the results of joint-preserving procedures. To accomplish this goal, some have advocated the use of hip arthroscopy8-10. However, this method relies on visual inspection of the articular surface and probing it to find abnormalities in texture or hidden defects within the midsubstance of the tissue. Less-invasive diagnostic measures, such as magnetic resonance imaging, would be preferable11.
