The VERSALOK rotator cuff anchor was developed to provide greater versatility in rotator cuff repair. The device allows surgeons the ability to address various tear pathologies with one implant and a variety of suture passing configurations including single row, dual row and suture spanning. The VERSALOK anchor expands by 29 percent post-deployment to provide solid fixation under the cortical bone. It facilitates consistent and reproducible fixation via a variety of suture spanning techniques with the ability to precisely control suture tension. The anchor is designed to firmly lock the suture in place completely between the sections of the implant and not the bone. This prevents suture unloading and suture creep to provide strength and durability of the repair.
