A graft fixation device for positioning and anchoring a bone graft within a bony channel. The fixation device generally comprises a rigid cylindrical member extending about a central axis, the member including an eccentric bore extending about an axis which is substantially parallel to, and radially offset from, the central axis. The fixation device is adapted to receive a rotational force applied to it. Rotation of the fixation device causes a bone plug installed and secured therein to move laterally within a bony channel, thus bringing the bone plug in contact with a portion of the channel wall. Preferably, the cancellous bone regions of the bone plugs and the bony channel are brought into abutting contact for optimum bone ingrowth opportunity and maximum graft fixation strength.

Graft fixation devices

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.
