Diagnosis, Evaluation, and Endoscopic Repair of Partial Articular Gluteus Tendon Avulsion.


ABSTRACT: In addition to trochanteric bursitis, gluteus medius and minimus tears (GMMTs) can be a common source of insidious lateral hip pain and dysfunction. Partial-thickness GMMTs are much more common than full-thickness GMMTs but are frequently overlooked by both radiologists and orthopaedic surgeons. GMMTs are commonly identified on magnetic resonance imaging ordered for lateral hip pain unresponsive to conservative management. Imaging can show that high-grade partial articular gluteus tendon avulsion (PAGTA) can occur as either an isolated gluteus medius tear, an isolated gluteus minimus tear, or a combined GMMT. We describe how to identify PAGTA injuries with intraoperative assessment and identification of the interval between the gluteus medius and minimus tendons to allow access to the PAGTA without violating the bursal side of the tendon. PAGTAs can be repaired arthroscopically by single- or double-row suture anchor fixation depending on the size of the tear. The purpose of this article is to guide orthopaedic surgeons in the recognition of PAGTA with magnetic resonance imaging and dynamic examination to allow for accurate repair of GMMTs.
