Intra-articular femoroacetabular impingement (FAI) is an abnormal contact of the acetabular rim and the femoral head-neck junction and can occur from either anterior or posterior conflicts. This condition causes labral and cartilage damage, leads to painful range of motion, and may cause osteoarthritis over time. In addition to the known intra-articular causes, recent advances in physical examination of the hip, as well as hip arthroscopy, have identified extra-articular causes of posterior femoroacetabular impingement. The purpose of this chapter is to discuss, in detail, the etiology, pathology, examination, and treatment of posterior femoroacetabular impingement. The goal is to describe the unique approach to this challenging diagnosis and offer the orthopedic surgeon new tools with which to return patients and athletes to their daily lives and to their respective sports.
