Abstract: An orthopaedic knee prosthesis includes a femoral component having a condyle surface. The condyle surface is defined by one or more radii of curvatures, which are controlled to reduce or delay the onset of anterior translation of the femoral component relative to a tibial bearing.

Abstract: An orthopaedic knee prosthesis includes a tibial bearing and a femoral component configured to articulate with the tibial bearing. The femoral component includes a condyle surface curved in the sagittal plane. The radius of curvature of the condyle surface decreases gradually between early-flexion and mid-flexion. Additionally, in some embodiments, the radius of curvature may be increased during mid-flexion.

Additionally, in some embodiments, the radius of curvature of the condyle surface may be increased during mid-flexion.

Abstract: A customized patient-specific orthopaedic surgical system including a first surgical block, a second surgical block, and a computer-controlled milling machine. The first surgical block includes a first bone-facing surface having a first customized patient-specific negative contour to receive a first corresponding contour of a bone of a patient and a first mounting surface. The second surgical block includes a second bone-facing surface having a second customized patient-specific negative contour to receive a second corresponding contour of the bone of the patient and a second mounting surface to be separately mated with the first mounting surface. The computer-controlled milling machine includes a third mounting surface to be separately mated with the first mounting surface of the first surgical block.

Abstract: An orthopaedic prosthesis includes a curved outer surface configured to abut a patient's bone when the orthopaedic prosthesis is implanted therein. The outer surface may or may not be electrically conductive. A channel is defined in the outer surface and extends from a rim of the outer surface to a location on the outer surface. One or more electrical conductors is positioned in the channel and extends outwardly from the channel at the rim of the outer surface. A switch is positioned at the first location and is configured to establish an electrical connection between the electrical conductor and the outer surface and/or another electrical conductor when the first location of the outer surface contacts the patient's bone. The switch may be embodied as an end of the electrical conductor or a more complex switch such as a push-button type switch.

Abstract: A knee replacement system includes a femoral component including a lateral condylar articulating portion and a medial condylar articulating portion, a tibial tray including an upper articulating surface, and a tibial insert including (i) a first articulating portion for articulating with the lateral condylar articulating portion with a first condylar dwell point, (ii) a second articulating portion for articulating with the medial condylar articulating portion with a second condylar dwell point, (iii) a lower articulating surface for articulating with the upper articulating surface, and (iv) a coupling member for coupling with the tibial tray and defining an axis of rotation about which the tibial insert rotates with respect to the tibial tray, the axis of rotation intersecting the upper articulating surface at a location posterior to a dwell axis including the condylar dwell points when the dwell axis is projected onto the upper articulating surface.
