1. A method for securing a soft tissue replacement in a bone tunnel comprising:
- forming a tunnel in a bone;
locating the soft tissue replacement in the tunnel;
passing a first tube member through an opening in the tunnel whereby the soft tissue replacement locates between the first tube member anda bone surface defining the tunnel;
passing a second tube member into the first tube member; and
injecting a flowable medium into the second tube member wherein the flowable medium passes through respective openings defined on the first and second tube members respectively and urging the flowable medium against the soft tissue replacement and into contact with the bone surface.

Abstract
A system and method to assist in securing a soft tissue replacement in a bone tunnel includes an expandable member having an opening and an expandable portion. A delivery structure includes a connection portion selectively coupled to the opening of the expandable member. The delivery structure is adapted to inject a flowable medium into the expandable member thereby expanding the expandable portion and urging the soft tissue replacement into a bone surface defining the bone tunnel.

5. A method for securing a soft tissue replacement in a bone tunnel comprising:
-
forming a tunnel in a bone; locating the soft tissue replacement in said tunnel; passing an expandable member into said tunnel, whereby the soft tissue replacement locates between said expandable member and a bone surface defining said tunnel, wherein said expandable member includes a sleeve member and a pin member extending through said sleeve member, said pin member having a distal end attached to said sleeve member and a proximal end extending from said sleeve member; and expanding said expandable member thereby urging said soft tissue replacement into contact with said bone surface, wherein expanding said expandable member includes translating said pin member relative to said sleeve member wherein said sleeve member expands outwardly as a result of said translation thereby urging the soft tissue replacement into the bone tunnel. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13)

14. A method for securing a soft tissue replacement in a bone tunnel comprising:
-
forming a tunnel in a bone; locating the soft tissue replacement in said tunnel; locating an expandable member into said tunnel having the soft tissue replacement between said expandable member and a bone surface defining said tunnel, wherein said expandable member includes a first outer member and a second inner member extending from said first outer member, said second inner member having a first end communicating with said first outer member and a second end extending from said first outer member; expanding said expandable member thereby urging said soft tissue replacement into contact with said bone surface, wherein expanding said expandable member includes translating said second inner member relative to said first outer member wherein said first outer member expands outwardly as a result of said translation thereby urging the soft tissue replacement into the bone tunnel; rotating said second inner member relative to a longitudinal axis of said first outer member; and removing said second inner member from said first outer member. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A method for securing a soft tissue replacement in a bone tunnel comprising:
-
forming a tunnel in a bone; locating the soft tissue replacement in said tunnel; locating an expandable member into said tunnel having the soft tissue replacement between said expandable member and a bone surface defining said tunnel, wherein said expandable member includes a first outer member and a second inner member extending from said first outer member, said second inner member having a first end communicating with said first outer member and a second end extending from said first outer member; expanding said expandable member thereby urging said soft tissue replacement into contact with said bone surface, wherein expanding said expandable member includes translating said second inner member relative to said first outer member wherein said first outer member expands outwardly as a result of said translation thereby urging the soft tissue replacement into the bone tunnel; and maintaining said expandable member at a static location while advancing said second inner member in a direction away from a distal tip of said expandable member.
