Abstract: A modular patella trial system and method is provided. A modular patella trial includes an articular element and at least one sizing element. The articular element has a length, a width, and a thickness. The articular element has a posterior and anterior surfaces separated by their thickness. The anterior surface has protrusions extending outwardly. Any of the sizing elements have a length, width, and thickness. Any such sizing elements have posterior and anterior surfaces separated by their thickness. At least one aperture extends through the posterior and anterior surfaces of the sizing elements. Such apertures are capable of receiving a corresponding protrusion of the articular element. The modular patella trial has a thickness substantially equal to the total of the thicknesses of the articular element and the sizing elements used in conjunction with the articular element.

Abstract: A prosthesis alignment guide includes a guide body that has an opening that extends at least partially therein and a first alignment hole extending entirely therethrough. The opening is configured to receive a trunnion of a joint prosthesis for mounting the guide body to the joint prosthesis. An alignment member is disposed within the first alignment hole and is axially moveable therein. A locking member is engaged to the guide body and moveable from a first position in which the locking member is disengaged from the alignment member and a second position in which the locking member engages the alignment member and secures it from axial movement within the first alignment hole.

Abstract: A knee prosthesis that includes a tibial component and femoral component. The tibial component includes an articular surface, a posterior portion and an anterior portion. The posterior portion includes a recess for receipt of a posterior cruciate ligament. The anterior portion includes a post extending therefrom. The post includes a posterior surface. The femoral component includes a condylar portion and an intercondylar portion. The intercondylar portion includes a posterior recess for receipt of the posterior cruciate ligament, a cam, and an engagement recess for receipt of the post. The cam includes a sliding surface and is disposed between the engagement recess and posterior recess. The sliding surface of the cam slides along the posterior surface of the post for restricting anterior subluxation of a femur bone when the articular surface and the condylar portion articulates through flexion of a knee joint.
