Resection shift guides and methods providing anterior, posterior, clockwise, or counterclockwise adjustment of a 4-in-1 cut guide along a planar resected surface of a femur are disclosed. A resection shift guide can include a base member and a block member. The base member can include first and second arms. The block member can include a first end, rotatably coupled with the first arm, a second end, rotatably coupled with the second arm, and at least three surfaces extending between the first and second ends. Each of the at least three surfaces can include two or more drill holes arranged differently than drill holes of the other surfaces. A method can include removing a 4-in-1 cut guide from two original femoral lumens, drilling two adjusted femoral lumens using a resection shift guide, removing the resection shift guides, and attaching the 4-in-1 cut guide to the two adjusted femoral lumens.

Knee implant systems and methods for implantation or use in a knee joint, are disclosed. A knee implant system can include at femoral component having a femur-contacting surface and an opposing articulation surface, and proximal, distal, anterior and posterior portion. The femoral component can include a medial condyle and a lateral condyle, where each of the condyles define respective distal-most points and have substantially equal widths. The width of each of the condyles can define respective condyle midpoints, where the distal-most points can be located laterally from the midpoints. The femoral component can include a trochlear groove that can define a distal-most sulcus point located halfway between the distal-most point of the medial condyle and the distal-most point of the lateral condyle.
