Femoroacetabular Impingement Syndrome

This article reviews diagnosis and management strategies for femoroacetabular impingement syndrome with a focus on recent literature. Abstract Femoroacetabular impingement (FAI) syndrome is one of the most rapidly evolving etiologies of hip pain. The 2016 Warwick Agreement consensus statement defined FAI syndrome as a triad of symptoms, signs, and radiographic findings. Cam morphology is more likely in athletes and is associated with repetitive hip loading in maximal flexion during adolescence. Much less is known about the development of pincer morphology. Physical therapy improves pain and function, justifying a trial before pursuing surgery. Musculoskeletal injections are utilized for FAI syndrome, but the evidence is limited. Arthroscopic surgery for FAI syndrome can correct the morphological changes and address the underlying soft tissue injuries. Recent studies evaluated reliable indicators of surgical outcomes, the most reliable of which is the presurgical presence of osteoarthritis. Recent studies demonstrate the efficacy of surgery, but with the risk of complication and no guarantee of a return to the same level of sport.
