Current surgical methods for rotator cuff repair involve sutures and bone anchors, which are successful in reattaching the torn tendon but have a 31% re-tear rate. To address this problem, a fastening device was created to reduce the likelihood of re-tear by increasing the surface area of attachment at the surgical site. The device was prototyped using 3D printing technology and underwent mechanical testing. The strength of the device surpassed that of the Mason-Allen suture technique, which is commonly used in rotator cuff repair.
