Abstract: A low profile patient specific cutting block for a knee includes a plurality of bone interfacing portions and a cutting slot. The plurality of bone interfacing portions are configured to overlie portions of an end of a bone. The bone interfacing portions each have a surface that is generally a negative of the portion of the bone that the respective bone interfacing portion overlies. The bone interfacing portions are angularly offset from each other such that a first of the bone interfacing portions overlies an anterior portion of the bone, and a second of the bone interfacing portions overlies a portion of bone generally perpendicular to the anterior portion of bone. The cutting slot is oriented in a fixed position relative to the bone interfacing portions such that the cutting slot directs a cutting tool at a fixed angle and at a fixed depth relative to the bone interfacing portions.

Abstract: Patient-matched surgical instruments and associated methods having an anatomy facing side including several discrete, physically separate anatomy contacting portions configured to match the anatomy of a particular patient and including one or more of non-uniform in distribution, non-uniform in shape and non-uniform in surface area.

Abstract: Methods, systems, and devices for replacement of a joint with a prosthetic system that replicates the natural kinematics of the joint is disclosed. A prosthetic system according to one embodiment includes a tibial component having a tibial plateau and a tibial stem portion, the tibial plateau having a top side and a bottom side, a tibial insert, with a bearing surface, adapted to be positioned on the top side of the tibial plateau, a femoral component having a base portion and a central housing, the femoral component having an axis of extension-flexion rotation, the base portion having a pair of condyles, an a mechanical linkage component linking the tibial component with the femoral component and with the tibial insert in between the tibial component and the femoral component, so that there is a center of contact between the condyles and the bearing surface.

Abstract: Certain embodiments generally provide an improved tibial base member comprising keel portions that allow one or both cruciate ligaments to be preserved. Other embodiments provide improved lateral and/or medial inserts having a mesial lip that helps relieve and/or prevent impingement between the femoral component and the tibial eminence. Other embodiments provide improved femoral components having various chamfers to provide additional clearance with respect to the tibial eminence and posterior cruciate ligament without decreasing bone coverage.
