View Edit Delete	OPT-13	FIGS. 3A-3D show the PS insert 12 of FIGS. 1A-2 in isolation. The PS insert 12 may include a fixation side 20, which may be an inferior side, opposite an articulation side 22, which may be a superior side. The articulation side 22 may include a medial tibial compartment 24 having a medial condylar articulation surface 25 and a lateral tibial compartment 26 having a lateral condylar articulation surface 27.	77	Added by DJM 1 2022	1/25/22, 12:00 AM
View Edit Delete	OPT-13	Referring to FIGS. 12A-12F, another alternative embodiment of a tibial insert 312 is shown. The tibial insert 312 may be referred to as a constrained condylar knee (CCK) tibial insert 312 (or “CCK insert”). The CCK insert 312 may include a fixation side 320, which may be an inferior side, opposite an articulation side 322, which may be a superior side. The articulation side 322 may include a medial tibial compartment 324 having a medial condylar articulation surface 325 and a lateral tibial compartment 326 having a lateral condylar articulation surface 327. A central portion 328 may separate the medial tibial compartment 324 from the lateral tibial compartment 326. A post 330 may protrude superiorly from the central portion 328, and extend from a post base 338 to a top, or post superior end 340. From the anterior perspective, as shown in FIG. 12E, and the posterior perspective, as shown in FIG. 12D, the post 330 may have its maximum medial-lateral or horizontal width at the superior end 340 of the post 330, and its minimum medial-lateral or horizontal width at the post base 338 of the post 330. The post 330 may be bilaterally symmetrical from the anterior and posterior perspectives. The CCK insert 312 may further include an insert base 346 and an engagement feature 348 for engagement with a tibial tray (not shown).	87	Added by DJM 1 2022	1/25/22, 12:00 AM
View Edit Delete	OPT-13	Referring to FIGS. 11A-11E, an alternative embodiment of a tibial insert 212 is shown. Tibial insert 212 may be referred to as a cruciate retaining tibial insert 212 (or “CR insert”). In a system of the disclosure, CR insert 212 may be implanted with the CR femoral component 114 and a tibial baseplate component (See FIG. 24A) to form a cruciate retaining knee prosthesis system. The CR insert 212 may include a fixation side 220, which may be an inferior side, opposite an articulation side 222, which may be a superior side. The articulation side 222 may include a medial tibial compartment 224 having a medial condylar articulation surface 225 and a lateral tibial compartment 226 having a lateral condylar articulation surface 227. A central portion 228 may separate the medial tibial compartment 224 from the lateral tibial compartment 226. A recess 245 may be formed posterior to the central portion 228, between the medial and lateral tibial compartments 224, 226, and may provide room for a posterior cruciate ligament. The CR insert 212 may further include an insert base 246 and an engagement feature 248 for engagement with a tibial baseplate component. The CR insert 212 may be coupled with the CR femoral component 114 to form a cruciate retaining assembly. This assembly may be implanted with a suitable tibial baseplate as a cruciate retaining knee prosthesis. The CR insert 212 may also be coupled with the PS femoral component 14 and implanted with a suitable tibial baseplate.	86	Added by DJM 1 2022	1/25/22, 12:00 AM
View Edit Delete	OPT-13	The medial and lateral articulation surfaces 32, 34 of the post 30 may be tapered and may permit natural articulation of the CR femoral component 114 with the PS insert 12, which may not be achievable if the post 30 were not tapered. For example, if the post 30 had straight sides instead of tapered sides, the wider width of the post 30 at the base of the post 30 would interfere with the internal articulating surfaces 170, 172 of the medial and lateral condyles 160, 164. When the PS femoral component 14 is coupled with the PS insert 12 to form assembly 10, as in FIG. 1A and FIG. 4, the circular shape of the post superior end 40 in combination with the tapered medial and lateral articulation surfaces 32, 34 of the post 30, may permit the PS femoral component 14 to articulate relative to the PS insert 12 in the manner of a posterior stabilized femoral component. However, when the PS insert 12 is paired and implanted with the CR femoral component 114, the resultant assembly 110 may provide the native articulation and rotation of a cruciate retaining implant.	85	Added by DJM 1 2022	1/25/22, 12:00 AM
