Abstract
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.
