摘要：
A tibial prosthesis (10) comprising: a distal surface (35)； a proximal surface (34) generally opposed to said distal surface； and a peripheral wall (25) extending between said proximal surface and said distal surface, said peripheral wall defines: a leading edge (202)； a lateral periphery that includes: a lateral edge (212) defining a tangent (212A) substantially perpendicular with respect to said anterior edge, an anterolateral corner that crosses an angular sweep (2L) between said anterior edge and says lateral edge to define a length of the anterolateral corner edge, and a posterior-lateral corner extending away from said lateral edge and said anterolateral corner； and a medial periphery that includes: a medial edge (222) defining a tangent (222A) substantially perpendicular to said anterior edge, an anteromedial corner that crosses an angular sweep (1R) between said anterior edge and said medial edge to define an anteromedial corner edge length that is greater than the length of the anterolateral corner edge, in which the angular sweep between said anterior edge and said medial edge is similar to the angular sweep between said anterior edge and lateral edge, and a corner medial post that extends away from said medial edge and said anteromedial corner； said anteromedial corner defines an anteromedial corner arc (220) defining a radius (R1R), of anteromedial corner said anterolateral corner defines an anterolateral corner arc (210) defining a radius (R2L), of anterolateral corner and said radius of Anteromedial corner is different from said anterolateral corner radius in as little as 48.1% and as much as 149.2%.Una prótesis (10) tibial que comprende: una superficie distal (35)； una superficie proximal (34) opuesta generalmente a dicha superficie distal； y una pared (25) periférica que se extiende entre dicha superficie proximal y dicha superficie distal, dicha pared periférica define: un borde (202) anterior； una periferia lateral que incluye: un borde (212) later
