What is femoroacetabular impingement

Femoroacetabular impingement (FAI) has gained much attention over the past decade. It has been associated with hip and groin pain, decreased hip function and can ultimately lead to osteoarthritis. A recent consensus meeting defined FAI as “a clinical entity in which a pathological mechanical process causes hip pain when morphological abnormalities of the acetabulum and/or femur, combined with vigorous hip motion (especially at the extremes), lead to repetitive collisions that damage the soft-tissue structures within the joint itself.” However, there is a lack of clarity regarding the definition of morphological abnormalities.
