A tibial support component (12, 112, 212) for articulation with a medial femoral condyle and a lateral femoral condyle, the tibial support component defines a system of coordinates of the tibial support component comprising: a transverse plane of the component of support that extends along a medial / lateral direction and an anterior / posterior direction； a coronal plane of the support component extending along a proximal / distal direction and the medial / lateral direction, said coronal plane of the support component perpendicular to said transverse plane of the support component； and a sagittal plane of the support component that extends along the anterior / posterior direction and the proximal / distal direction, said sagittal plane of the support component perpendicular to said transverse plane of the support component and said coronal plane of the component of support, said tibial support component (12, 112, 212) comprises: an articular surface and an opposite distal surface (60, 160, 260), said distal surface parallel to the transverse plane of the support component, said articular surface that includes the medial and lateral articular compartments (16, 18； 116, 118； 216, 218) sized and configured for articulation with the medial and lateral femoral condyles respectively, said articular medial and lateral articular compartments separated from each other by the sagittal plane of the component of support, wherein said medial articular compartment (16, 116, 216) is concave, characterized in that said articular compartment lateral (18, 118, 218) is, in addition, concave, said lateral articular compartment (18, 118, 218) comprises a plurality of coronal transverse profiles defining a lateral set of more distal coronal points that encompass an anterior / posterior lateral extension (APL), said lateral set of more distal coronal points define a lateral articular pathway (28, 128, 228), said articular pathway having an anterior portion and a posterior portion (30),
