Abstract
A guide is disclosed that operates to guide in the creation of a bone spur to facilitate harvesting a quadriceps tendon and includes an end having a width equal to a desired graft width with a terminal slope equal to a cutting angle desired. In use, the guide may be initially positioned parallel to the femur to form guide cuts in the patella. The guide is then rotated ninety degrees to allow an angled cut at the guide cut. The guide is again rotated, this time one hundred eighty degrees and a second angled cut made on the other guide cut. A final lateral cut is made and the bone spur may be lifted from the patella.

- and
- a terminal portion extending generally along the primary longitudinal axis, but at an angle thereto from the first end of the elongated handle portion, the terminal portion comprising:
- a flat portion extending away from the first end of the elongated handle portion generally along the primary longitudinal axis, but at an angle thereto, the flat portion having a bottom side and a corner spaced from the first end of the elongated handle portion;
- a post extending from the bottom side perpendicular to the flat portion;
- and
- an upwardly sloping wall configured to act as a saw guide, the upwardly sloping wall extending upwardly from the corner and wherein the post extends from the flat portion in a first direction and the upwardly sloping wall extends from the flat portion in a second direction generally opposite the first direction.
