Endoscopic Gluteus Medius Repair Augmented With Bioinductive Implant

Abstract

Patients with gluteus minimus and medius tears that fail nonoperative management may be indicated for surgical repair; however, structural failure after gluteal tendon repair remains unacceptably high. This is likely related to the limited healing potential of tendinous tissue, which is poorly vascular and heals by formation of fibrocartilaginous scar tissue rather than histologically normal tendon. An emerging option to augment tendon healing is the use of a bioinductive implant that is designed to amplify the host healing response and induce the formation of healthy tendon tissue. Though it is rapidly being adopted for partial- and full-thickness rotator cuff tears, this implant has not yet been used in the hip. A detailed technical description and a discussion of the advantages and disadvantages of the technique are provided.
