Abstract: A reference jig comprises a base adapted to be secured to a distal end of a bone. An adjustment mechanism has a bracket, one or more rotational joints operatively mounting the bracket to the base, whereby the bracket is rotatable in two or more rotational degrees of freedom relative to the base, and one or more translational joints. A landmark alignment unit is operatively connectable to the bracket by the at least one translational joint, the landmark alignment unit having a bone alignment component configured to be aligned with at least one bone landmark.

Abstract: A tibia cutting assembly includes a tibia cut guide with at least one cut slot. A guide rod has a guide holder mountable to the cut guide at a first end of the guide rod, and a second end of the guide rod is mountable non-invasively about a skin of a patient. The guide rod is extendable in length to displace the tibia cut guide and adjust a position thereof with respect to a tibia of the patient. The guide holder cooperates with the tibia cut guide to adjust an orientation of the tibia cut guide. A first inertial sensor is mountable to the guide holder and is displaceable therewith, and a second inertial sensor is mountable to the guide rod at the second end thereof.
