New perspectives on femoroacetabular impingement syndrome

Key PointsFemoroacetabular impingement (FAI) between an abnormal proximal femur or acetabulum, or both, results in repetitive microtrauma and early damage to the cartilage and labrum of the hip jointRestricted hip range of motion in FAI can increase the risk of other associated injuriesArthroscopic management of FAI is minimally invasive and results in reduced morbidity compared with open surgery techniquesProspective studies are required to clarify the progression of subtle FAI morphology into hip osteoarthritis
