Resection Guide to Alter Distal Femoral Flexion

A cutting guide for resecting a bone to receive an implant, the cutting guide comprising:

• a body configured to be positioned adjacent to the bone;
• a slot extending through the body and configured to receive a cutting edge, the cutting edge being configured to resect the bone;
• and
• an opening extending though the body, the opening being configured to receive a rod,
• wherein when the rod is disposed in an intramedullary canal of the bone and the opening of the body is passed over the rod, a portion of the body is rotatable in a sagittal plane and about a central longitudinal axis extending through a length of the bone such that a cutting plane through the slot changes relative to the bone as the body is rotated.

A method for preparing a bone for receiving an implant, the method comprising:

• reaming a hole through the bone;
• anchoring a rod within the hole;
• positioning an opening of a cutting guide over the rod and onto an end portion of the bone such that cutting guide is in a first orientation relative to the bone;
• and
• moving the cutting guide and a portion of the rod positioned through the opening relative to the bone into a second orientation relative to the bone,
• wherein in the first orientation a slot of the cutting guide is coincident with a first plane, and in the second orientation the slot of the cutting guide is coincident with a second plane, each of the first plane and the second plane being defined relative to the bone, and
• wherein the first plane defines a first cutting path through the bone and the second plane defines a second cutting path through the bone, the first plane and second plane being at different slopes relative to the bone.
