摘要： Methods and apparatus for performing knee arthroplasty, including, but not limited to, bicruciate retaining knee arthroplasty, are described herein. Methods and apparatus for preparing a distal femur for a femoral implant as well as methods and apparatus (270) for preparing a proximal tibia for a tibial implant are described. These methods and apparatus, in at least some embodiments and uses, facilitate decreasing the complexity of knee arthroplasty procedures such as bicruciate retaining procedures, while maintaining, if not improving on, the safety, accuracy and/ or effectiveness of such procedures.

摘要： A method includes accessing image data representing tissue and identifying one or more features of the tissue indicated by the image data. A model is selected for the tissue based on the one or more identified features. The image data is segmented and, using the model, one or more anatomical landmarks of the tissue indicated by the segmented image data are identified.

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 positions a profile (60) of a prosthetic component on the three-dimensional model of a limb. Patient-specific anatomical data of the limb is gathered. First (32b) and second (32a) anatomical landmarks are identified to determine a first spatial relationship. A third anatomical landmark (34) 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 (31a) is identified to position the profile of the prosthetic component in the one remaining degree of freedom.
