Femoroacetabular impingement (FAI) is a pathomechanical process of the hip, which can occur in every individual but has a higher prevalence in physically active subjects such as athletes. It is mainly due to bony deformities at the proximal femur and/or acetabulum in conjunction with rigorous or supraphysiological hip ranges of motion. FAI may lead to chondrolabral lesions, hip pain and development of early hip osteoarthritis. Symptomatic FAI patients may present functional limitations during daily activities and sports, reduced hip muscle strength as well as hip joint kinematic and kinetic alterations during weight-bearing activities.
