A review of outcomes of the surgical management of femoroacetabular impingement

Abstract

INTRODUCTION: Femoroacetabular impingement (FAI) resulting from abnormal contact between the acetabulum and femur has been studied extensively in recent years owing to its association with acetabular labrum tears and possible contribution to the development of osteoarthritis. METHODS: A comprehensive PubMed, MEDLINE® and Embase™ literature search was conducted. Search terms included 'femoroacetabular impingement', 'pathophysiology', 'diagnosis', 'dGEMRIC', 'arthroscopic', 'open', 'mini-open' and 'outcome measure'. RESULTS: A range of radiographic features have been described, and computed tomography and magnetic resonance imaging are both commonly used in the diagnosis of the bony abnormalities in FAI. Treatment of FAI is surgical with methods of treatment ranging from open surgical hip dislocation to arthroscopic osteochondroplasty. CONCLUSIONS: In recent years, a trend towards the use of arthroscopic treatment for FAI has been seen, with promising results from a range of studies. However, only short-term outcome data are available and a range of different outcome measures have been used in studies to date. We present an overview of the outcomes for a range of surgical treatment methods for FAI and discuss the outcome measures used.
