Abstract: A method includes registering a joint of a patient in physical space with a model of the joint in virtual space and planning a planned placement of an implant to be implanted in the joint by performing a soft tissue assessment of the joint and fitting a representation of the implant relative to the model of the joint based on a result of the soft tissue assessment. The method also includes providing, based on the planned placement, a limit on movement of a surgical tool to facilitate preparation of the joint to receive the implant in the planned placement.

Abstract: Described are computer-based methods and apparatuses, including computer program products, for implant planning for multiple implant components using constraints. A representation of a bone and a representation of a first implant component are displayed with respect to the representation of the bone. A representation of a second implant component is displayed, wherein the first implant component and the second implant component are physically separated and not connected to each other. A positioning of the representation of the second implant component that violates at least one positioning constraint is prevented, wherein the positioning constraint is based on the representation of the first implant component.

Abstract: A method of relating an object to a coordinate system, the object being supported by a support element, and the object and the support element being housed within a housing, includes engaging a registration element with the object or the support element, conducting an optical surface scan of the object and the registration element, using an optical scanner, to form a three-dimensional surface image of the object, the three-dimensional surface image having the coordinate system associated therewith, with the registration element being associated with the coordinate system, and correlating the object with the registration element in the three-dimensional surface image so as to register the object with the coordinate system. Associated methods and systems are also provided.

Abstract: Described are computer-based methods and apparatuses, including computer program products, for implant planning using areas representing cartilage. A predetermined number of control points for generating a predetermined number of areas representing cartilage are determined, wherein the predetermined number of control points are based on an implant component. Measurements corresponding to a plurality of measured cartilage points are received, wherein each cartilage point is based on an associated control point from the predetermined number of control points. A plurality of areas representing cartilage are generated, wherein each area representing cartilage is larger than and projects to an associated control point from the plurality of control points. A representation of the implant component is positioned based on a representation of a bone, the representation of the bone comprising representations of the plurality of areas representing cartilage.
