    Abstract:
    The indications for hip arthroscopy are expanding as the understanding of hip disease increases. Improved instrumentation and technical skills also have facilitated the ability to treat some hip disorders arthroscopically. Femoroacetabular impingement (FAI) is increasingly recognized as a disorder that can lead to progressive intra-articular chondral and labral injury. Although FAI is usually treated through an open approach, limited-open and all-arthroscopic approaches have been described. Various arthroscopic techniques allow treatment of labral and acetabular rim pathology as well as peripheral compartment femoral head-neck abnormalities. Early outcomes of limited-open and all-arthroscopic treatment of FAI are only beginning to be reported but appear to compare favorably with those of open dislocation procedures. Although labral tears traditionally have been treated with simple débridement, concerns have been raised about the consequences of removing the labrum. Modified portal placement and hip-specific suture anchors are now being used in an effort to repair some labral tears. Snapping hip disorders typically are treated nonsurgically. For persistent symptoms, arthroscopic release is successful, compared with open release, and allows additional evaluation of the hip joint during surgery. Diagnosis and management of traumatic and atraumatic hip instability continue to be challenging. Hip arthroscopy has been shown to be effective in the treatment of hip instability in some patients. The extra-articular peritrochanteric space is receiving increased attention. The arthroscopic anatomy has been well defined, but the treatment of greater trochanteric pain syndrome and arthroscopic repair of abductor tendon tears are only beginning to be reported. Improved techniques and longer-term outcomes studies will further define the optimal role of hip arthroscopy.
