Femoroacetabular impingement: Avoiding arthroplasty

Femoroacetabular impingement (FAI) is caused by structural alterations of the hip joint and can lead to abnormal stresses to the cartilage and labrum. FAI can cause pain and early osteoarthritis. Diagnosis of FAI is based on specific clinical and radiographic features. While the efficacy of nonoperative treatment of FAI is unknown, various operative treatments, including surgical hip dislocation, anteversion periacetabular osteotomy, and hip arthroscopy, have shown successful outcomes.
