Claim:
1. A medical device, comprising: a tibial implant having an inferior surface and an opposite, superior surface, the inferior surface being configured to be fixed to a tibia of a patient; a femoral implant mateable to the tibial implant and having an inferior surface and an opposite, superior surface, the superior surface being configured to be fixed to a femur of the patient, and the tibial implant being configured to articulate relative to the femoral implant when the tibial implant is fixed to the tibia and the femoral implant is fixed to the femur; a femoral intercondylar notch coupled to the femoral implant; and a post extending from the superior surface of the tibial implant near an edge thereof such that the post simulates an anterior cruciate ligament (ACL) when the tibial implant is fixed to the tibia and the femoral implant is fixed to the femur, the post occupying a greater proportion or volume of a lateral portion of the femoral intercondylar notch than a medial portion of the femoral intercondylar notch thereby defining a space adjacent the post configured to accommodate a posterior cruciate ligament (PCL), wherein the space is configured such that a first mediolateral distance measured from a medial surface of the post to a medial surface of the femoral intercondylar notch is greater than a second mediolateral distance measured from a lateral surface of the post to a lateral surface of the femoral intercondylar notch.
