Ankle replacement system and method

Apparatus comprising:

• a position adjustable tool holder mountable to at least two pins that project from respective anterior facing locations near a distal end of a tibia, the position adjustable tool holder located in first and second frames for adjusting a position of the tool holder in the proximal-distal and medial-lateral directions so as to be lockable in the proximal-distal and medial-lateral directions while being configured for detachably mounting a first tool configured for at least one of sizing a tibia implant, drilling, or cutting a tibia;
• and
• a tibia tray detachably mountable on the position adjustable tool holder, while the tool holder is located in a first coordinates in the proximal-distal and medial-lateral directions, the tibia tray.

A system for providing a common reference location for surgical tools comprising:

• a tool holder;
• two pins located on respective anterior facing locations near a distal end of a tibia;
• a first frame and a second frame arranged and configured for adjusting a position of the tool holder in the proximal-distal and medial-lateral directions relative to at least one of the two pins, wherein a first tool is mounted to the tool holder, the first tool configured for sizing a tibia implant and a second tool mounted to the tool holder, the second tool configured for removing a portion of a tibia for acceptance of a tibia implant, wherein the first frame is coupled to each one of the two pins such that a locking screw urges a portion of the frame to bear against at least one of the two pins so as to secure the tool holder relative to the two pins.
