View Edit Delete	OPT-13	A number of knee replacement options exist which may be implemented depending upon the level of compromise of the natural knee anatomy. The knee anatomy complex includes the knee joint between the femur distal end and the tibia proximal end, and the surrounding anterior and posterior cruciate ligaments (ACL, PCL), and medial and lateral collateral ligaments (MCL, LCL), which provide support and stabilization to the knee joint. When one or more ligaments are compromised, for example through injury, disease, or aging, a knee prosthesis system or assembly may be implanted to replace the knee joint.	2	Added by DJM 1 2022	1/25/22, 12:00 AM

View Edit Delete	OPT-13	FIGS 24D and 24E show lateral and medial views of the insert 2410, respectively. In 24D, the lateral tibial compartment 2414 with lateral perimeter 2429 is shown. The lateral articulation surface 2421 may meet the lateral perimeter 2429 at a lateral high point 2430. The lateral low point 2431 may be toward the center of the lateral articulation surface 2421. In 24E, the medial tibial compartment 2413 with medial perimeter 2426 is shown. The medial articulation surface 2420 may meet the medial perimeter 2426 at a medial high point 2427 at or adjacent the medial posterior section 2422. The medial low point 2428 may be closer to the medial anterior section 2423 and toward the medial perimeter 2426. The high points 2427 2430 and low points 2428 2431 on both the medial tibial compartment 2413 and lateral tibial compartment 2414 are in relation to the insert interface 2411. The difference between the medial high point 2427 and the medial low point 2428 may be greater than the difference between the lateral high point 2430 and the lateral low point 2431 The greater difference in height on the medial articulation side may be represented by the medial ramp 2419.	119	Added by DJM 1 2022	1/25/22, 12:00 AM
View Edit Delete	OPT-13	The femoral component 2401 includes a femoral articulation surface that includes a medial condylar articulation surface 2404 and lateral condylar articulation surface 2405. In certain embodiments, the femoral articulation surface may include one of the medial condylar articulation surface 2404 and the lateral condylar articulation surface 2405. In other embodiments, the femoral articulation surface may include both of the medial condylar articulation surface 2404 and the lateral condylar articulation surface 2405.	110	Added by DJM 1 2022	1/25/22, 12:00 AM
View Edit Delete	OPT-13	The medial 2402 and lateral 2403 condyles may include the medial condylar articulation surface 2404 and the lateral condylar articulation surface 2405. The femoral component 2401 may include elements to secure the femoral component 2401 in the femur of the patient. For example, the femoral component 2401 may include at least one keel 2406 and at least one post 2407 that penetrate the bone of the associated femur (not shown) to secure the femoral component 2401 to the femur. The at least one post 2407 may be placed on the femoral side of the medial condyle 2402 and/or the lateral condyle 2403. The femoral component 2401 may include surface texturing on the bone-facing side to encourage bone in-growth and securement.	111	Added by DJM 1 2022	1/25/22, 12:00 AM
View Edit Delete	OPT-13	The tibial baseplate component 2440 may be configured to be secured to the tibia of the patient. As used herein, “baseplate" refers to a structure, component, apparatus, or device that serves as a foundation or frame for other structures, components, apparatuses, or devices that may be coupled or connected to the baseplate. In certain embodiments, a baseplate may have a generally planar structure.	112	Added by DJM 1 2022	1/25/22, 12:00 AM
View Edit Delete	OPT-13	The tibial baseplate component 2440 may include an insert interface 2441 configured for the placement and securement of the insert 2410, with one or more tibial posts 2442, which may be inserted and secured into a patient’s tibia. The tibial baseplate component 2440 may further have a base 2443, which may also be designed to penetrate the tibial plateau and may receive a separate keel (not shown) that penetrates more deeply into the intramedullary canal of the tibia. As used herein, a "base" refers to a main or central structure, component, or part of a structure. A base is often a structure, component, or part upon which, or from which other structures extend, are coupled to, or connect to. A base may have a variety of geometric shapes and configurations. A base may be rigid or pliable. A base may be solid or hollow. In one embodiment, a base may include a housing, frame, or framework for a larger system, component, structure, or device. In certain embodiments, a base can be a part at the bottom or underneath a structure designed to extend vertically when the structure is in a desired configuration or position.	113	Added by DJM 1 2022	1/25/22, 12:00 AM
View Edit Delete	OPT-13	FIG. 24A shows the exploded assembly 2400 from a lateral side configured for placement in a left knee and shown in approximately 90 degree extension, or “flexion.” While the tibial baseplate component 2440 and the femoral component 2401 may be medially and laterally symmetric across an anterior-posterior plane, the insert 2410 may be medially-laterally asymmetric. The insert 2410 may include a fixation side or insert interface 2411 configured to mate or engage with the insert interface 2441 of the tibial baseplate component 2440. The insert interface 2411 may have features complementary to features on the insert interface 2441. The complementary features may allow for a removable fit for the insert 2410. The removable fit may allow for a modular assembly 2400, benefitting the surgeon and the patient.	114	Added by DJM 1 2022	1/25/22, 12:00 AM
View Edit Delete	OPT-13	In some embodiments, the tibial baseplate component 2440 and the femoral component 2401 may be symmetric, as mentioned previously, enabling them to be used for either left or right knee replacements. Only the insert 2410 may be specific to one side or the other. An assembly for either left or right knee arthroplasty may include only one femoral component 2401, one tibial baseplate component 2440, and two (e.g., left and right) inserts 2410. This may greatly reduce the inventory requirements for the system.	115	Added by DJM 1 2022	1/25/22, 12:00 AM
View Edit Delete	OPT-13	Opposite the insert interface 2411, the insert 2410 has a tibial articulation surface 2412 configured for engagement with the medial 2402 and lateral 2403 condyles on the femoral component 2401. The tibial articulation surface 2412 may include a medial tibial compartment 2413 and a lateral tibial compartment 2414. The medial tibial compartment 2413 may include a medial articulation surface 2420 for direct engagement with the medial condylar articulation surface 2404. The lateral tibial compartment 2414 may include a lateral articulation surface 2421 for direct engagement with the lateral condylar articulation surface 2405. The medial condylar articulation surface 2404 may engage with the medial articulation surface 2420 at a medial dwell point 2435. As used herein, "dwell point" refers to a point or an area where two articular surfaces contact each other during flexion and/or extension of a joint.	116	Added by DJM 1 2022	1/25/22, 12:00 AM
