BACKGROUND Femoroacetabular impingement (FAI) is one of the most common causes of early cartilage and labral damage in the nondysplastic hip. Biomarkers of cartilage degradation and inflammation are associated with osteoarthritis. It was not known whether patients with FAI have elevated levels of biomarkers of cartilage degradation and inflammation. HYPOTHESIS Compared with athletes without F...

Hip and groin pain has, for many years, been a difficult diagnostic challenge. In the past decade there has been increased focus on femoroacetabular impingement (FAI) as a cause. FAI is now considered by many as a primary cause of hip joint degeneration. Our appreciation and understanding of FAI is currently increasing at an exponential rate. In this paper we review FAI as a pathology and revie...

Young adults with hip pain secondary to femoroacetabular impingement (FAI) are rapidly being recognised as an important cohort of orthopaedic patients. Interest in FAI has intensified over the last decade since its recognition as a precursor to arthritis of the hip and the number of publications related to the topic has increased exponentially in the last decade. Although not all patients with ...

Surgery for femoroacetabular impingement (FAI) has been advocated for correction of cam and pincer hip joint morphology. Surgery for FAI was first pioneered by Myers et al, who surgically treated FAI by open dislocation. Arthroscopy was then introduced in 2005 by Sampson. Arthroscopy has continued to develop since then, with the intent of providing pain relief and improving function in patients...

Femoroacetabular impingement (FAI) is a clinical syndrome resulting from abnormal hip joint morphology and is a common cause of hip pain in young adults. FAI has been posited as a precursor to hip osteoarthritis (OA); however, conflicting evidence exists and the true natural history of the disease is unclear. The purpose of this article is to review the current understanding of how FAI damages ...

BACKGROUND Previous studies reporting the impact of osteoarthritis (OA) on pain and function after hip arthroscopy largely predate resection of femoroacetabular impingement (FAI). QUESTIONS/PURPOSES We determined (1) functional improvement after resection of FAI impingement lesions in patients with preoperative radiographic joint space narrowing, and (2) identified preoperative predictors of ...

Magnetic resonance imaging (MRI) has become a valuable technology for the diagnosis and treatment of femoroacetabular impingement (FAI). This article reviews the basic pathophysiology of FAI, as well as the techniques and indications for MRI and magnetic resonance arthrography. Normal MRI anatomy of the hip and pathologic MRI anatomy associated with FAI are also discussed. Several case examples...

Femoroacetabular impingement (FAI) is a relatively recently described but important cause of hip pain which frequently affects young and otherwise healthy patients. FAI results from an abnormal contact between the acetabulum and the femur secondary to a variety of morphologic abnormalities of the hip. There are two types of FAI, termed cam impingement and pincer impingement, which have distinct...
