Hip arthroscopy in adults.

The acceptance and rates of hip arthroscopy are increasing in the United States and abroad and the literature describing it is expanding. Indications for hip arthroscopy include labral tears, loose bodies, femoroacetabular impingement, ruptured ligamentum teres, chondral injuries, adhesive capsulitis, instability, synovial disease, disorders of the iliopsoas tendon, external coxa saltans, tears of the hip abductors, and diagnosis of unresolved intra-articular hip pain. Current techniques in the central and peripheral compartments include, but are not limited to, labral debridement, labral repair, chondroplasty, microfracture, synovectomy, loose body removal, acetabuloplasty, proximal femoral osteoplasty, and iliopsoas release, with other procedures possible in the peritrochanteric space. Long-term outcomes are limited, but early data shows good results for many arthroscopic procedures in the hip when they are performed in the absence of degenerative disease. Improved techniques and technology are allowing for more advanced procedures to become popularized, but long-term outcome data about hip arthroscopy is still relatively sparse.
