An orthopedic button assembly providing the ability to perform a soft tissue repair or bone repair using a method for securing sutures or fixation members in a knotless manner is described. The orthopedic button assembly of the present disclosure is designed in a manner to as to not rely on an additional component to perform the locking. The orthopedic button assembly of the present disclosure includes the ability to optimally tension the repair by pulling the tensionable fixation members (e.g. sutures) in the tensioning direction and prevent slippage of the tensionable fixation members in the opposite direction by capturing the tensionable fixation members in a manner such that pulling on the tensionable fixation members in the direction opposite of the tensioning direction (e.g., if connected tissue or bone were to attempt to 'pull away' from the button assembly under tension) actually increases the tension, resulting in a tighter locking interface to increase the security of the repair.

Knotless orthopedic stabilization system and related methods

Embodiments of knotless button-suture assemblies for orthopedic stabilization are disclosed. The button-suture assembly includes a button having a first opening, a second opening and a center opening. The assembly further includes a tensioning member having two tensioning member ends exiting from the first opening and the second opening of the button and disposed in the proximal direction. The assembly further includes a locking pin mated with the button through the center opening of the button in such a manner that allows a proximal movement of the tensioning member when a pulling force is applied to the tensioning member ends towards a proximal direction and prevents a distal move-ment of the tensioning member when the pulling force applied to the loose ends of the tensioning member ceases to exist.

Knotless orthopedic stabilization system

Button-suture assemblies which employ a knotted locking mechanism do not maintain tension when securing bone and tissue fragments. A knotless method and device for maintaining tension and providing precise placement of a button-suture assembly during stabilization procedures comprising a locking pin, which mates with a button creating pinch points with increased surface area through which suture can pass from a baseplate through two dedicated openings in the button, one for the first end of the suture and one for the second end of the suture while preventing tension loss during the locking step and therefore allowing for precise placement of the button-suture assembly.

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 in the opposite direction. The release member may be used to bend or deflect the locking element to loosen the tensionable fixation member to enable an operator to readjust the tension in the tensionable fixation member to the operator's liking.

Re-tensionable suture anchor system and related methods

A knotless anchor assembly method and device comprising an anchor and a compression member, wherein the anchor further comprises a pilot tip and anchor body. During procedures to tension the knotless anchor assembly, the anchor is driven into bone or other surface or component, and the tension member is urged into the anchor body recess. The compression member is secured in the anchor body to lock the tension member in place. The knotless anchor assembly gives the surgeon or user the ability to optimize tensioning by having the ability to change tension in the tension member by adjusting the compression member during or after the repair.
