Failed hip arthroscopy: causes and treatment options.

Abstract

Indications for arthroscopic surgery of the hip have increased over the past several years, along with the number of procedures performed annually. In addition, the number of unsuccessful procedures and subsequent revision surgeries have also increased. Recent literature has defined several common causes for failed hip arthroscopy. Severe osteoarthritis and osteonecrosis are associated with poor outcomes. Findings during revision hip arthroscopy consistently demonstrate untreated femoroacetabular impingement, chondral defects, labral tears, and postoperative adhesions. The treating surgeon must be diligent in his or her indications for surgery, as well as in addressing all pathology at the initial surgery.
