Endoscopic Gluteus Medius and Minimus Repair With Allograft Augmentation Using Acellular Human Dermis.

Recently, attention has been given to recalcitrant lateral hip pain, also known as greater trochanteric pain syndrome. Although, historically, this has been attributed to greater trochanteric bursitis, the literature has shown that many patients will have a lesion of the gluteus medius and minimus tendons. Endoscopic hip abductor tendon repair has been shown to provide good outcomes with decreasing overall morbidity and is becoming more popular. However, failure rates have been reported to be as high as 35%, likely due to the poor tissue quality in this older population. Acellular human dermal allograft has been used to augment rotator cuff repairs in an attempt to improve tendon healing. The technique described in this Technical Note shows endoscopic gluteus medius and minimus repair with acellular human dermal allograft augmentation focusing on graft preparation, implantation, and fixation in a safe and reproducible manner.
