The method includes determining that the knee joint has the condition; implanting a femoral component on the femur, the femoral component may include a femoral articulation surface; implanting a tibial baseplate component on the tibia, the tibial baseplate component may include an insert interface; based on the condition, selecting a tibial insert configured for the second side, the tibial insert may include a baseplate interface attachable to the insert interface of the tibial baseplate component, the tibial insert may include a tibial articulation surface configured to articulate with the femoral articulation surface to adapt kinematics of the knee joint; and connecting the selected tibial insert to the tibial baseplate to adapt kinematics of the knee joint based on the condition. 13 Added by DJM 1 2022 1/25/22, 12:00 AM

Delete 		OPT-13 Implementations may include one or more of the following features. The knee joint prosthesis system where the knee joint is a right knee joint of the patient; and where the left side tibial insert is attached to the insert interface of the tibial baseplate component of the right knee joint such that the left side tibial insert constrains the femoral articulation surface within the medial tibial compartment and mitigates the condition. The tibial articulation surface facilitates tibiofemoral rotation within the medial tibial compartment during flexion of the knee joint where the condition is a valgus knee joint. The tibial articulation surface adjusts mediolateral stability during flexion of the knee joint where the condition is a varus knee joint. The tibial articulation surface increases constraint on a lateral collateral ligament of the knee joint and decreases tension on a medial collateral ligament of the knee joint. The medial tibial compartment may include a medial perimeter, a medial high point, and a medial low point and where each of the right side tibial insert and the left side tibial insert may include a lateral tibial compartment that may include a lateral perimeter, a lateral high point, and a lateral low point. Each of the right side tibial insert and the left side tibial insert may include a lateral tibial compartment and a medial tibial compartment and where the femoral articulation surface may include a medial femoral compartment and a lateral femoral compartment and where the medial tibial compartment engages the lateral femoral compartment at a lateral dwell point during flexion and the lateral tibial compartment engages the medial femoral compartment at a medial dwell point during flexion. 12 Added by DJM 1 2022 1/25/22, 12:00 AM

The lateral dwell point migrates anteriorly and outwardly and the medial dwell point migrates posteriorly and outwardly. In one embodiment, the medial femoral compartment and the lateral femoral compartment are symmetrical. The tibial insert may include one of a cruciate retaining tibial insert, a constrained condylar knee tibial insert, a posterior stabilizing tibial insert, and a medially-laterally asymmetric tibial insert and the condition may include one of a varus condition and a valgus condition. 10 Added by DJM 1 2022 1/25/22, 12:00 AM

Delete 		OPT-13 Accordingly, such patients need a knee prosthesis that facilitates tibiofemoral rotation during flexion of a patient's knee with a condition. Such patients may also need a knee prosthesis that increases mediolateral stability during flexion during flexion. The present disclosure addresses these needs. 4 Added by DJM 1 2022 1/25/22, 12:00 AM

Delete 		OPT-13 A typical knee prosthesis system includes a tibial bone anchoring component, a tibial articulating component, which may be called a tibial insert, and a femoral bone anchoring component. Certain patients have experience different conditions in one knee or both knees that differ from accepted healthy knees. For example, one patient may present a right side knee that is in a varus condition while another patient may present with a right side knee in a valgus condition. Of course, other patients may present with a left knee or both knees in one or more of a varus and/or a valgus condition. For such patients, implanting a conventional knee prosthesis may result in a knee joint having constrained tibiofemoral rotation during flexion. Or, implanting a conventional knee prosthesis may result in a knee joint having less mediolateral stability during flexion. 3 Added by DJM 1 2022 1/25/22, 12:00 AM

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
