Abstract

Femoroacetabular impingement (FAI) results from abnormal anatomic relationship between acetabulum and femoral head-neck junction, which causes secondary chondrolabral injury. FAI is the common cause of hip joint pain in young adults who have nearly normal hip joint structure. The pain usually progresses on hip flexion and internal rotation. Although it is still controversial whether FAI is one of the reason of secondary hip osteoarthritis or the contrary, instruments and surgical technique for treating FAI is continuing to improve. When we initially diagnosed with FAI, conservative treatment is recommended. But if the conservative treatment has no response, we can consider surgical intervention. The arthroscopic technique is one of the promising options, and it is the fastest growing fields for the treatment FAI.
