Paragraph Number

79

A central portion 28 may separate the medial tibial compartment 24 from the lateral tibial compartment 26. A post 30 may protrude superiorly from the central portion 28 and extend from a post base 38 to a post top or post superior end 40. From the anterior perspective (shown in FIG. 3B) and/or the posterior perspective (shown in FIG. 3A), the post 30 may have its maximum medial-lateral or horizontal width toward the post superior end 40 of the post 30, and its minimum medial-lateral or horizontal width toward the post base 38 of the post 30. The post 30 may also be bilaterally symmetrical from the anterior and/or posterior perspectives. A recess 45 may be formed posterior to the central portion 28, between the medial and lateral tibial compartments 24, 26, and may provide room for a posterior cruciate ligament (not shown). The PS insert 12 may further include an insert base 46, which may further include an engagement feature 48 for engagement with a tibial baseplate component.
