In proximal hamstring tendonitis, or tendinosis, there are small tears in the proximal hamstring tendon, where they insert on the ischial tuberosity, or the sit bone. And this can progress to larger tears or even traumatic full thickness tears of the proximal hamstring. And for this, especially for tendinosis, we try non-surgical interventions such as physical therapy, injections and anti-inflammatories, however if in tendinosis this is not helping, or there is a full thickness tear we consider doing a reattachment or a repair of those tendons. And that entails doing a small open incision in the gluteal crease, and reattaching those tendons back to the ischium using suture anchors and suture.
