View Edit Delete	OPT-13	The post 330 may have an articulation surface 331 extending around the post 330 on the medial, posterior, lateral, and anterior aspects of the post 330. The articulation surface 331 may include a medial articulation surface 332, a lateral articulation surface 334, an anterior post surface 336, and a posterior articulation surface 342. The medial and lateral articulation surfaces 332, 334 may taper slightly inward from the post superior end 340 to the post base 338 of the post 330 relative to an insert midline vertical axis 2. However, some embodiments of CCK insert 312 may include no taper of the medial and lateral articulation surfaces 332, 334. The medial articulation surface 332 may be continuous with the medial condylar articulation surface 325, and the lateral articulation surface 334 may be continuous with the lateral condylar articulation surface 327. The anterior post surface 336 may extend between the medial and lateral surfaces 332, 334 and may be convexly rounded. The anterior post surface 336 may taper outward from the post superior end 340 to the post base 338 relative to the midline axis 2, as best seen in FIG. 12F. In other embodiments of the CCK insert 312, the anterior post surface 336 may include less taper, more taper, and/or no taper. The post 330 of the CCK insert 312 may be wider and bigger in diameter than the post 30 of PS insert 12, for example to provide increased stability in the case of removal of the collateral ligaments.	88	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
View Edit Delete	OPT-13	Referring to FIGS. 9 and 10, another assembly 110 embodiment of the disclosure may include the PS insert 12 of FIGS. 1-8 coupled with a cruciate retaining femoral component 114 (or “CR femoral component”). The CR femoral component 114 may include medial and lateral condyles 160, 164, with a gap 168 formed between the medial and lateral condyles 160, 164. As a CR femoral component 114, no cam bar or box may be present. The medial and lateral condyles 160, 164 may include medial and lateral condylar articulation surfaces 162, 166, and an internal articulation surface 154 with medial and lateral articulating surfaces 170, 172.	84	Added by DJM 1 2022	1/25/22, 12:00 AM
View Edit Delete	OPT-13	The PS femoral component 14 depicted in FIGS. 1-8 may include a cam element or cam bar 50 and a box structure 52 for providing posterior stabilization in place of absent ligaments. The cam bar 50 may include a cam articulating surface 51 which may contact the posterior articulation surface 42 of the post 30 during flexion, as in FIGS. 1B and 7. An internal articulation surface 54 may reside on the inside of the box structure 52 and may contact the post 30 during articulation and rotation of the knee joint. The internal articulating surface 54 may be concavely curved and may contact the rim 44 of the post 30 during axial rotation of the knee joint about the post. The PS femoral component 14 may further include a medial condyle 60 having a medial condylar articulation surface 62, and a lateral condyle 64 having a lateral condylar articulation surface 66. The medial and lateral condylar articulation surfaces 62, 66 may articulate against the PS insert 12 medial and lateral condylar articulation surfaces 25, 27, respectively. A gap 68 may be formed between the medial and lateral condyles 60, 64, with the cam bar 50 extending medial-laterally across the gap 68. The internal articulation surface 54 may include a medial portion 70 continuous with a lateral portion 72. In the embodiment depicted, a fixation post 74 may protrude superiorly from the PS femoral component 14. However, in other embodiments of the PS femoral component 14, the fixation post 74 may be absent and/or other fixation features such as posts, spikes, pegs, webs, keels, or teeth may be present to affix the PS femoral component 14 to a prepared femur (not shown).	83	Added by DJM 1 2022	1/25/22, 12:00 AM
View Edit Delete	OPT-13	Referring to FIG. 3C, the boundary of the post superior end 40 defines a rounded rim 44 shaped as a portion of a circle defined by a circular envelope 47, as seen from a superior perspective. The post superior end 40 and rim 44 may be crescent-shaped with a concave recess toward a posterior end of the post 30 as shown and may permit passage of the posterior cruciate ligament. The post superior end 40 may be circular; the rim 44 may provide increased rotational range of motion and surface contact against the femoral component 14 in comparison to traditional posts with a more square or rectangular shape and no rim. Thus, the rounded post superior end 40 and rim 44 may allow for surface contact with the femoral component 14 in contrast to the mere point or edge contact that is achieved by traditional posts that do not have these features.	82	Added by DJM 1 2022	1/25/22, 12:00 AM
View Edit Delete	OPT-13	The articulation surface 31 may include a medial articulation surface 32, a lateral articulation surface 34, an anterior post surface 36, and a posterior articulation surface 42. The medial and lateral articulation surfaces 32, 34 may be non-parallel to one another and taper inward from the post superior end 40 to the post base 38 relative to an insert midline vertical axis 2, as shown in FIGS. 3A and 3B. As shown in FIG. 3A, an angle θ between the vertical axis 2 and each tapered surface 32, 34 may be about 6.5°, in at least one embodiment. Since the post 30 may be bilaterally symmetrical, the angle θ may be the same on both the medial and lateral articulation surfaces 32, 34 of the post 30. In other embodiments of the disclosure, angle θ may range from about 6° to 11° degrees. The medial articulation surface 32 may be continuous with the medial condylar articulation surface 25, and the lateral articulation surface 34 may be continuous with the lateral condylar articulation surface 27, as can been further seen in cross-section in FIGS. 6 and 8. The anterior post surface 36 may extend between the medial and lateral articulation surfaces 32, 34 and may be convexly rounded. The anterior post surface 36 may also taper outward from the post superior end 40 to the post base 38 relative to the midline vertical axis 2, as best seen in FIG. 3D. In other embodiments of the PS insert 12, the anterior post surface 36 may include less or no taper.	81	Added by DJM 1 2022	1/25/22, 12:00 AM
View Edit Delete	OPT-13	Continuing with FIGS. 1A-3D, the post 30 may have an articulation surface 31 extending around the post 30 on the medial, posterior, lateral, and anterior aspects of the post 30. As used herein, "articulation" refers to a joint or juncture between bones or cartilage in a skeleton of a vertebrate. In certain embodiments, "articulation" may also refer to the action or manner of jointing or interrelating, or the state of being jointed or interrelated (search "articulation" on Merriam-Webster.com. Merriam-Webster, 2021. Web. 15 Nov. 2021. Modified.)	80	Added by DJM 1 2022	1/25/22, 12:00 AM
View Edit Delete	OPT-13	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.	79	Added by DJM 1 2022	1/25/22, 12:00 AM
