    Abstract: Systems for determining force balance on a knee joint during a surgical procedure are disclosed. A system can include a tibial prosthesis. The tibial prosthesis can include a bearing component, a base component, and a shim component. The bearing component can have a superior articulating surface and an inferior surface. The bearing component can include a top portion, a bottom portion, a frame disposed between the top portion and the bottom portion, and a plurality of sensors disposed between the frame and the bottom portion. The frame can have a plurality of apertures corresponding in size or shape to the plurality of sensors. The base component can have a superior surface and an inferior surface. The shim component can be configured to be slidable between the inferior surface of the bearing component and the superior surface of the base component in an anterior to posterior direction.

    Abstract: A method of anatomically positioning screw holes in an acetabular implant that can be used in surgery, such as a total hip arthroplasty. In some examples the method can be used to position holes in a shell of the implant. The method can include, for example, obtaining anatomic data including data defining an arch of bone behind an acetabulum of the living being, the arch of bone extending from a superior anterior portion to an inferior posterior portion of the acetabulum. The method can further include positioning a first series of holes along a first arched line within the acetabular shell, the first arched line determined based on the anatomic data for the arch of bone proximate the acetabulum of the living being.

    Abstract: Tibial prosthesis systems for implantation or use in a knee joint are disclosed. A tibial prosthesis system for implantation on a resected tibia can include a bearing component, a base component, and a shim component. The insertion of the shim component can provide spacing adjustment between the bearing and base components. The shim component can have a generally uniform height or thickness, or a variable height. A cut guide attachment, removably attachable to the prosthesis system, can be used to facilitate further resection of the tibia and create one or more additional resection surfaces on the tibia at an angle relative to the first resection surface. Multiple cut guide attachments can be available to the user to provide various resection angles. The cut guide attachment can include a modular design. The cut guide attachment can be configured to adjust the angle of the subsequent resection in at least one direction.

    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.
