1. An orthopaedic prosthesis system, comprising:
a femoral component configured to be coupled to a distal end of a patient's femur, the femoral component including a pair of condyles and a notch extending from an open posterior end that is defined between the pair of condyles,
a tibial tray component configured to be coupled to a proximal end of a patient's tibia, and
a plurality of tibial insert components configured to be separately attached to the tibial tray component, each tibial insert component including an anterior end, a posterior end, and medial and lateral concave surfaces shaped to engage the condyles of the femoral component,
wherein the plurality of tibial insert components includes a first tibial insert component and a second tibial insert component,
wherein an anterior-posterior dimension is defined between the anterior end and the posterior end of each of the plurality of tibial insert components, and the anterior-posterior dimension of the first tibial insert component is substantially equal to the anterior-posterior dimension of the second tibial insert component,
wherein the medial concave surface of the first tibial insert component has a distal-most point positioned a first distance from the posterior end of the first tibial insert component when the first tibial insert component is viewed in a first sagittal plane, and
wherein the medial concave surface of the second tibial insert component has a distal-most point positioned a second distance from the posterior end of the second tibial insert component when the second tibial insert component is viewed in a second sagittal plane, the second distance being greater than the first distance.
