A material fixation system, comprising: an implant, which is placeable in a tunnel disposed in a portion of bone, wherein the tunnel is defined by walls comprised of bone; a first member which is deployable outwardly to engage the tunnel walls for anchoring said implant in place in the tunnel; a second member (14, 16) which is deployable outwardly to engage tissue material to be fixed within said tunnel, and to move the tissue material outwardly into contact with the tunnel walls; a third member which is movable to deploy said first member outwardly; and a fourth member for actuating said third member to move in order to deploy said first member; wherein said fourth member comprises a portion which functions to deploy said second member outwardly said implant comprises a body having a distal end and a proximal end, and said first member is disposed on said body; characterized in that; said first member comprises an arm which is pivotally attached to said body; said third member comprises a wedge which is movable generally axially to deploy said arm; said fourth member comprises a deployment screw having a distal end and a proximal end, said deployment screw being adapted to extend axially through said body, the distal end of said deployment screw having a threaded portion which is engageable with a complementary threaded portion on said wedge, wherein rotation of said deployment screw causes relative movement of said deployment screw and said wedge; said second member comprises a compression pad (14, 16); said fourth member comprises a head of said deployment screw, disposed on the proximal end thereof. an implant, which is placeable in a tunnel disposed in a portion of bone, wherein the tunnel is defined by walls comprised of bone; a first member which is deployable outwardly to engage the tunnel walls for anchoring said implant in place in the tunnel; a second member (14, 16) which is deployable outwardly to engage tissue material to be fixed within said tunnel, and to move the tissue material outwardly into contact with the tunnel walls; a third member which is movable to deploy said first member outwardly; and a fourth member for actuating said third member to move in order to deploy said first member; wherein said fourth member comprises a portion which functions to deploy said second member outwardly said implant comprises a body having a distal end and a proximal end, and said first member is disposed on said body; characterized in that; said first member comprises an arm which is pivotally attached to said body; said third member comprises a wedge which is movable generally axially to deploy said arm; said fourth member comprises a deployment screw having a distal end and a proximal end, said deployment screw being adapted to extend axially through said body, the distal end of said deployment screw having a threaded portion which is engageable with a complementary threaded portion on said wedge, wherein rotation of said deployment screw causes relative movement of said deployment screw and said wedge; said second member comprises a compression pad (14, 16); said fourth member comprises a head of said deployment screw, disposed on the proximal end thereof.
