A graft preparation instrument includes a first mold including first protrusions disposed on a first working surface of the first mold. The first protrusions are separated by first spaces. A second mold includes second protrusions disposed on a second working surface of the second mold. The second protrusions are separated by second spaces. The first and second molds are movable from an open position of the instrument to a closed position of the instrument. In the open position, the first and second working surfaces are separated by an open position distance large enough to place a graft therebetween. In the closed position, the first and second working surfaces are separated by a closed position distance such that the first protrusions are operable to form indentations in a first surface of the graft and the second protrusions are operable to form indentations in a second surface of the graft.
