摘要： A low profile patient specific cutting block for a knee comprises 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 generally a negative of the portion of the bone the 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 hone. 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 from the bone interfacing portions.

摘要： An improved implant having components comprising an oxidized zirconium bearing surface adapted to decrease pain, lower friction, and minimize wear when coupled with natural femoral articular cartilage. The improved implant components also provide for reduced backside wear effects in fixed and mobile implants. The improved implant components further provide for more ideal wear coupling between components in mobile bearing implants.

摘要： A method positions a profile of a prosthetic component on the three-dimensional model of a limb. Patient-specific anatomical data of the limb is gathered. First and second anatomical landmarks are identified to determine a first spatial relationship. A third anatomical landmark is identified to determine a second spatial relationship with respect to the first spatial relationship. The profile of the prosthetic component is positioned in all but one degree of freedom. A fourth anatomical landmark is identified to position the profile of the prosthetic component in the one remaining degree of freedom.

摘要： A method of resecting distal and anterior portions of a distal portion of a femur for a bicompartmental prosthesis is provided. The method includes generating a geometric representation of the distal portion of the femur. A virtual anterior resection plane is calculated at a predetermined depth and is oriented at a predetermined angle relative to the femur. The method identifies a distal-most point of a lateral portion of the virtual anterior resection plane and an AP line. A varus/valgus angle and an anterior-posterior distance are calculated. Anterior and distal resection guides are navigated according to the parameters calculated from the method.
