Abstract
A system and method comprising an anchor assembly including an anchor and a locking element, a tensionable fixation member (e.g., surgical suture, tape, etc.), and a release member, wherein the anchor further comprises a first end, second end and anchor body. The anchor is configured for implantation into bone. One end of a tensionable fixation member is configured for attachment to a tissue to assist with fixation of the soft tissue. Once the anchor has been seated in bone, the second end of the tensionable fixation member is pulled through a “one-way only” passage in the body of the anchor. When the tensionable fixation member enters passage, it traverses past the locking element positioned within the anchor by bending or deflecting the locking element out of the way to permit passage of the tensionable fixation member while maintaining contact with the tensionable fixation member via elastic compression that results from the elastic bending or deflection of the locking element but prevents the tensionable fixation member from passing back. This continuous locking on the tensionable fixation member creates fixation security, allows for optimal tensioning, and prevents loosening i…
