Femoroacetabular Impingement: A Review.

Femoroacetabular impingement (FAI) is one of the most researched conditions in sports medicine today. FAI occurs due to abnormal morphology and subsequently contact between the proximal femur and the acetabulum. With repetitive loading, this femoroacetabular mismatch can be a source of labral and chondral injuries. FAI is more prevalent in the athletic population, particularly those athletes who participated in high level activities at a younger age. If nonoperative management is failed, surgical treatment is often done arthroscopically and with good results. This review attempts to provide an overview of the pathophysiology, diagnosis, and potential treatment options of FAI with a focus on the most recent literature.
