The platform member defines a slot extending between the first edge and the second edge, a first opening between the slot and the first edge, and a second opening between the slot and the second edge. The tissue graft attachment device includes a first filament passing through the first opening, a second filament passing through the second opening, and a graft connecting element passing through the slot to form a loop. ## Claims ### Claim 1 A tissue graft attachment device comprising: a platform member comprising: a first edge and a second edge connected to the first edge by a top side and a substantially curved bottom side; a first side surface and a second side surface, each of the first side surface and the second side surface connecting the first edge, the second edge, the top surface and the bottom surface; a slot formed through the platform member from the first side surface to the second side surface, the slot extending between a location closer to the first edge and a substantially central location between the first edge and the second edge; a first opening extending through the platform member from the first side surface to the second side surface, the first opening at a location between the slot and the first edge; and a second opening extending through the platform member from the first side surface to the second side surface, the second opening at a location between the slot and closer to the second edge; wherein a portion of the first and second side surfaces extending from the substantially central location to the second opening, and from the top side to the bottom side, defines a solid surface. ### Claim 2 (depends on 1) The device of claim 1, wherein the slot extends along a central axis, and the first opening and the second opening are formed on the central axis. ### Claim 3 (depends on 1) The device of claim 1, wherein the first opening and the second opening each have a substantially circular cross-section. ### Claim 4 (depends on 1) The device of claim 1, wherein the slot is defined by a first inner edge and a second inner edge connected by a first inner side positioned between a central axis and the bottom side of the platform member and a second inner side positioned between the central axis and the top side of the platform member, and wherein the first inner side defines a shoulder near the central location. ### Claim 5 (depends on 1) The device of claim 1, wherein the top side of the platform member is substantially curved. ### Claim 6 (depends on 5) The device of claim 5, wherein the top side of the platform member and the bottom side of the platform member are defined by a respective first radius of curvature and a second radius of curvature, wherein the first radius of curvature is different from the second radius of curvature. ### Claim 7 (depends on 1) The device of claim 1 wherein the platform member defines a curved central axis, the curved slot defines a curved slot axis, and curved slot axis coincides with the curved central axis. ### Claim 8 (depends on 1) The device of claim 1, wherein the first opening and the second opening each have a cross-section that is one of square and rectangular. ### Claim 9 (depends on 1) The device of claim 1, further comprising a first filament passing through the first opening. ### Claim 10 (depends on 1) The device of claim 1, further comprising a second filament passing through the second opening. ### Claim 11 (depends on 1) The device of claim 1, further comprising a graft connecting element passing through the slot to form a loop. ### Claim 12 (depends on 11) The device of claim 11, wherein the graft connecting element is a third filament. ### Claim 13 (depends on 11) The device of claim 11, wherein the graft connecting element is a rigid band. ### Claim 14 A tissue graft attachment device comprising: a platform member including a first edge and a second edge connected to the first edge by a top side and a bottom side, the platform member defining a slot extending between the first edge and the second edge; a graft connecting element passing through the slot to form a loop; and a filament coupled to the platform member and the graft connecting element such that manipulating the filament moves the graft connecting element in the slot; wherein a first end of the filament passing through the slot after being passed through a first opening between the slot and the first edge comprises the first end passing through the loop formed by the graft connecting element. ### Claim 15 (depends on 14) The device of claim 14, wherein the first end of the filament passed through the first opening, the slot, and the loop further comprises: the first end passed through a second opening between the slot and the second edge; the first end passed through the first opening after being passed through the second opening; the first end passed through the slot after being passed through the first opening; and the first end passed through the first opening after being passed through the slot.
