  • Publication number: 20190209331
    Abstract: A method of manufacturing at least one component of a joint prosthesis, the method comprising creating a first database representing an anatomy of an articulating bone of a joint of a subject; accessing a second database representing a geometry of a generic prosthetic component being sized to fit around an outer articulating surface of the articulating bone of the joint of the subject; creating a third database representing kinematic data of the subject's joint; merging the databases within a three-dimensional image-based medium. The generic prosthetic component is attached to the outer articulating surface of the articulating bone of the joint creating a prosthetic articulating surface that is moved through the kinematic data of the subject through a bearing template thereby modifying the bearing template to create a kinematically appropriate bearing surface; and manufacturing the component of the joint prosthesis to have a geometry corresponding to the kinematically appropriate bearing surface.

  • Publication number: 20170135610
    Abstract: Systems and methods provide patient position information to a user. A patient positioning device is placed on a patient in a predefined location. The patient positioning device determines a relative patient position with respect to at least one known reference axis. The patient positioning device communicates patient position information including or with reference to the at least one known reference axis. The communicated patient position information allows the user to position the patient and/or a surgical tool using the communicated patient position information.
