A small-stature tibial baseplate , comprising: a tibial plateau comprising: a distal surface sized and shaped to substantially cover a proximal resected surface of a tibia (T); a proximal surface opposite said distal surface, said proximal surface having a lateral compartment and a medial compartment opposite said lateral compartment, wherein the lateral compartment is asymmetric with respect to the medial compartment about a component anteroposterior axis to define a component asymmetry; and a peripheral wall extending between said distal surface and said proximal surface , wherein a total surface area bounded by the peripheral wall of the tibial plateau is between about 1390 mm 2 and about 1580 mm 2 ; a tibial keel extending distally from said distal surface of said tibial plateau to an opposing distal tip to define a longitudinal tibial keel axis, the tibial keel having a longitudinal extent defined between the distal surface and the distal tip, the keel having a conical, tapered outer profile; and at least one fin spanning a junction between said tibial keel and said distal surface , said at least one fin comprises a medial fin and a lateral fin, said medial fin and said lateral fin cooperating to define a medial/lateral fin extent (ML KA ) of about 40 mm, said at least one fin comprising a fin edge defining an angle (γ A ) of about 45 degrees with respect to said longitudinal tibial keel axis wherein said at least one fin extends along less than an entire longitudinal extent (PD KA ) of said tibial keel_ . a tibial plateau comprising: a distal surface sized and shaped to substantially cover a proximal resected surface of a tibia (T); a proximal surface opposite said distal surface, said proximal surface having a lateral compartment and a medial compartment opposite said lateral compartment, wherein the lateral compartment is asymmetric with respect to the medial compartment about a component anteroposterior axis to define a component asymmetry; and a peripheral wall extending between said distal surface and said proximal surface , wherein a total surface area bounded by the peripheral wall of the tibial plateau is between about 1390 mm 2 and about 1580 mm 2 ; a distal surface sized and shaped to substantially cover a proximal resected surface of a tibia (T); a proximal surface opposite said distal surface, said proximal surface having a lateral compartment and a medial compartment opposite said lateral compartment, wherein the lateral compartment is asymmetric with respect to the medial compartment about a component anteroposterior axis to define a component asymmetry; and a peripheral wall extending between said distal surface and said proximal surface , wherein a total surface area bounded by the peripheral wall of the tibial plateau is between about 1390 mm 2 and about 1580 mm 2 ; a tibial keel extending distally from said distal surface of said tibial plateau to an opposing distal tip to define a longitudinal tibial keel axis, the tibial keel having a longitudinal extent defined between the distal surface and the distal tip, the keel having a conical, tapered outer profile; and at least one fin spanning a junction between said tibial keel and said distal surface , said at least one fin comprises a medial fin and a lateral fin, said medial fin and said lateral fin cooperating to define a medial/lateral fin extent (ML KA ) of about 40 mm, said at least one fin comprising a fin edge defining an angle (γ A ) of about 45 degrees with respect to said longitudinal tibial keel axis wherein said at least one fin extends along less than an entire longitudinal extent (PD KA ) of said tibial keel_ . <EOS>
