92

FIGS. 16A-16D show the PS insert 1012 of FIGS. 15 and 14 in isolation. The PS insert 1012 may include a fixation side 1020, which may be an inferior side, opposite an articulation side 1022, which may be a superior side. The articulation side 1022 may include a medial tibial compartment 1024 having a medial condylar articulation surface 1025 and a lateral tibial compartment 1026 having a lateral condylar articulation surface 1027. A central portion 1028 may separate the medial tibial compartment 1024 from the lateral tibial compartment 1026. A post 1030 may protrude superiorly from the central portion 1028 and extend from a post base 1038 to a post top 1040 or post superior end. From the anterior perspective (shown in FIG. 16B) and/or the posterior perspective (shown in FIG. 16A), the post 1030 may have its maximum medial-lateral or horizontal width toward the top 1040 of the post 1030, and its minimum medial-lateral or horizontal width toward the base 1038 of the post 1030. The post 1030 may also be bilaterally symmetrical from the anterior and/or posterior perspectives. A recess 1045 may be formed posterior to the central portion 1028, between the medial and lateral tibial compartments 1024, 1026, and may provide room for a posterior cruciate ligament (not shown). The PS insert 1012 may further include an insert base 1046, which may further include an engagement feature 1048 for engagement with a tibial baseplate component.
