The invention relates to a base (1) that includes 1) a means (11) for osseous attachment onto a tibia, and ii) a plate (13) having posterior, anterior, medial and lateral edges; a posterior pin (15.1) and an anterior pin (15.2) having a posterior flat section (16.1) and an anterior flat section (16.2); two posterior lugs (17.1, 18.1) protruding above the plate (13) and arranged on the posterior edge (14.1) of each side of the posterior pin (15.1); and two anterior lugs (17.2, 18.2) arranged on each side of the anterior pin (15.2). The posterior flat section (16.1) and the anterior flat section (16.2) are arranged so as to simultaneously engage with the insert. Each posterior tab (17.1, 18.1) comprises a support extension (17.11, 18.11) for inserting, in an anteroposterior direction, a complementary support tab (57.11, 58.11) of the insert. Each anterior lug (17.2, 18.2) comprises a means for snap-coupling the insert onto the base (1).
