The cadaveric data show that labral lesions are extremely common, present in 93% of specimens.

Because the labrum is thought to be a stabilizing structure in the hip, labral pathology might contribute to the development of osteoarthritis in a number of ways. Injury or degeneration of the labrum could result in instability of the femoral head in the acetabulum, resulting in cartilage damage adjacent to the damaged labrum. This instability might also be more "global," resulting in cartilage damage in the weight-bearing region of the acetabulum.

If it can be clearly shown that labral lesions contribute to cartilage degeneration, then the early recognition and treatment of these lesions will become an important part of os-teoarthritis prevention.
