Abstract
A guide and other tools for cutting a bone graft from, e.g., the patella. The guide includes a guiding portion configured to engage a bone cutting instrument (such as a saw with a curved cutting surface), and a bone-engaging portion insertable into a cut in the surface of the bone to position the guiding portion in a selected orientation with respect to the bone. During use, the guiding portion directs the bone cutting instrument to cut the graft in the selected orientation. One of the other tools used with the guide is a spacer which has a bone-engageable portion insertable into the cut in the bone surface, and a surface arranged with respect to the bone-engageable portion and configured to guide a saw in making a second cut in the bone surface parallel to the first-mentioned cut. The guide includes a housing that supports the guiding portion, and arms secured to the housing and on which the bone-engaging portions of the guide are disposed. Another one of the tools used with the guide is a clamp which clamps the guide housing to the bone.
