    Abstract: A tibial baseplate is described. While the baseplate can include any suitable component, in some instances, it includes a first surface and a second surface, the second surface being substantially opposite to the first surface and the first surface being configured to be seated on a resected surface at a proximal end of a tibia. In some cases, the baseplate also includes a first spacer coupling that is configured to couple a first spacer to at least one of a lateral side and a medial side of the baseplate such that the spacer is disposed between, and is configured to maintain a set minimal distance between, the proximal end of the tibia and a distal end of a femur when the tibial baseplate is seated on the resected surface at the proximal end of the tibia and the spacer is coupled to the tibial baseplate. Other implementations are discussed.

    Abstract: A medical device to facilitate a distal femoral cut of a femur of a patient is described herein. Such medical devices can include a base having a planar surface along a first plane between a distal end and a proximal end of the base. The medical device also includes one or more projections extending from the distal end of the base. The medical device also includes a cutting guide used to guide cutting of the distal femoral cut and a mounting mechanism that is used to releasably couple the cutting guide to the proximal end of the base. The base, the one or more projections, and the cutting guide are configured to engage various surfaces femoral condyles of the femur when the medical device is placed on a knee joint without requiring insertion of an intermedullary femoral rod into the femoral canal of the knee.

    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.
