A new osteotome for dividing bone adjacent to a bone tunnel, the osteotome comprising: a handle (205) having a proximal end and a distal end, and defining a longitudinal axis extending from the proximal end to the distal end a blade (210) disposed at the distal end of the handle (205), the blade (210) having a first side and a second side in opposition to one another, the first side being configured for placement toward the bone tunnel and at least one of the handle (205) and the blade (210) defining a lumen (215) therethrough, the lumen (215) being substantially parallel to the longitudinal axis of the handle (205) wherein the osteotome is configured for advancement over a guide device chosen from a group consisting of a guide pin and a guidewire (125), the guide device extending from bone adjacent to the bone tunnel, the osteotome is advanced into the bone, and the osteotome is withdrawn from the bone so as to create an opening through the bone adjacent to the bone tunnel with an intervening layer of bone therebetween.
