Abstract

A method and apparatus for coupling a soft tissue implant into a locking cavity formed within a bone is disclosed. The apparatus includes a member to pull the soft tissue implant into a femoral tunnel. The member includes a suture having first and second ends which are passed through first and second openings associated with the longitudinal passage to form a pair of loops. A collapsible tube is positioned about the suture. Application of tension onto the suture construction causes retraction of the soft tissue implant into the femoral tunnel and the collapse of the tube to form an anchor.
