Abstract: The present disclosure provides a provisional tibial prosthesis system for a set of prosthetic knee joints for implantation in a natural knee, the provisional tibial prosthesis system including a bearing component and a bearing support, the spacing of the bearing component from the bearing support is adjustable to allow for representation of a variety of different sized final tibial prostheses. In this system, only one provisional bearing component corresponding to each level of constraint is needed and shims are used to adjust the spacing of the bearing component from the bearing support. The shims are slidably insertable between the bearing component and the bearing support in an anterior/posterior direction to allow for adjustment of the spacing of the bearing component from the bearing support. The number of provisional components needed during knee surgery is reduced and adjustment of the system only requires the knee join to be distracted by a distance equal to the height of a particular shim.

Abstract: Tibial prosthesis systems for implantation or use in a knee joint are disclosed. A tibial prosthesis system can include a bearing component, a base component, a shim component, and optionally a spacer component. The shim or spacer component can be inserted between an inferior surface of the bearing component and a superior surface of the base component. The insertion of the shim or spacer component can provide spacing adjustment between the bearing and base components. The shim component can include one or both of a medial edge having a different height than a lateral edge or an anterior edge having a different height than a posterior edge. The differing edge height of the shim component can provide a surgeon with knee joint kinematic insight regarding an angled bone cut before the cut is made, and can allow for sizing of an appropriately permanent prosthesis system using a reduced number of provisional components.

Abstract: Tibial prosthesis methods for balancing a knee joint during a surgical procedure are disclosed. A method can comprise inserting a first tibial shim component between a tibial bearing component and a tibial base or a tibial plate component in an anterior/posterior direction. The first tibial shim component can include one or both of a medial edge having a different height than a lateral edge or an anterior edge having a different height than a posterior edge. The method can further comprise testing one or more of a stability, a force balance, or a range of motion of a knee joint in which the first tibial shim component is inserted. If the testing result is not satisfactory, the method can include removing the first tibial shim component, and inserting a second tibial shim component between the tibial bearing component and the tibial base or tibial plate component in the anterior/posterior direction.
