Femoroacetabular impingement is a cause of groin pain, which frequently afflicts young, active patients. Patients with irregularities in the morphology of the proximal femoral head–neck junction are at risk for developing impingement of the acetabular labrum. Furthermore, the cam effect causes compression and avulsion of acetabular cartilage and can result in irreversible degenerative changes in the joint of these relatively young patients. Understanding the anatomy responsible anterior impingement and disorders of the acetabular rim is essential for joint preservation. Arthroscopic debridement may alleviate acute labral symptoms but does not address the underlying osseous anatomy; treatment should include osteoplasty of the proximal femur to improve the anterior head–neck offset and allow clearance of the anterior acetabular rim. A case is presented to highlight the presentation, exam, diagnosis and treatment recommendations for patients with anterior femoroacetabular impingement.
