ABSTRACT:
An instrument and kit for harvesting a bone-patella tendon-bone (BTB) graft having substantially cylindrical bone plugs, and a method for harvesting a BTB graft. The instrument comprises two cylindrical shell portions extending along an axis from a drive end to a cutting end. One of the shell portions, which is positionable around a portion of the tendon, includes an axial slot which permits the graft portion of the tendon to extend therethrough. The shell portions interlock together in a hinged and mutually biased engagement to form a cylindrical tube around the graft portion, with a cutting edge that extends a full 360 degrees about the axis of rotation. Bone plugs obtained using the instrument are fully circular in cross-section for substantially their entire length.
