POSTERO-STABILIZED PROSTHESIS WITH ANTI-TIPPING TIBIAL PLOT

摘要

P Tibial insert of a so-called posterior stabilized prosthesis, comprising a tibial stud (2) projecting perpendicularly from the base of the insert, and having a face (6) facing the posterior side, characterized in that in cross section in the sagittal plane, or anteroposterior, the posterior face (6) defines a curve, called contact curve, which has, at least in part, the shape of a concave curve having its concavity turned towards the posterior side, a point (22) of the curve, in particular the vertex, at a distance from the base, being more posterior than other points (25) of the curve, in particular most of the other points of the curve. / P
