Gluteal Undersurface Concealed Crescent Injury Endoscopic Deep Surface Repair

Partial-thickness articular-sided gluteus medius and minimus tears-referred to as gluteal undersurface concealed crescent injury lesions-can cause debilitating pain. Persistent symptoms despite nonoperative care indicate operative management. Conventional endoscopic repair techniques for partial-thickness gluteal tears have commonly involved a transtendinous approach, which involves tendon splitting, anchor placement, and knot tying. Despite satisfactory outcomes, several characteristics of conventional techniques may perpetuate pain and irritation postoperatively and result in prolonged operative and recovery times. This technical note describes a tissue-sparing gluteal undersurface concealed crescent injury tear repair using all-suture knotless anchors in an "X-linked" compressive configuration (GUCCI-X).
