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.

The modular stem component may include a shaft portion, a head, and a sleeve. The shaft portion is configured for receipt within the intramedullary canal of a bone and the head is configured to receive another component of a modular prosthetic system, such as a femoral neck, thereon. In one exemplary embodiment, the head extends radially around at least a portion of the stem and includes a rib defining a flange extending therefrom. The sleeve, which is formed as an independent part of the modular stem component and is made at least partially of a highly porous biomaterial, includes opposing ends and has a bore extending therethrough. The bore is configured to facilitate sliding receipt of the sleeve on the head.
