    Abstract: In accordance with one or more embodiments herein, a system for optimizing a position of an implant having an individually customized implant hat H and at least one implant protrusion P extending from the implant hat H in the direction of an implant axis A in an anatomical joint of a patient is provided. The system comprises a storage media 110 and a processor 120 which is configured to: receive medical image data representing a three dimensional image of the joint from the storage media 110; obtain a three dimensional virtual model of the joint which is based on the received medical image data; identify damage in the joint based on the received medical image data and/or the three dimensional virtual model of the joint; define an implant area that covers at least a major part of the identified damage; position a virtual implant template having an implant hat H corresponding to said implant area in the three dimensional virtual model of the joint; and generate a customized top surface of the implant hat H to correspond to a simulated healthy cartilage surface. The processor is configured to position the virtual implant template by: placing the virtual implant template so that the cross section area of the implant hat H in a direction perpendicular to the implant axis A covers at least a major part of the damage; and optimizing the tilt of the implant axis A, while maintaining the position of the cross section area of the implant hat H in the joint, by minimizing at least one of the maximum penetration depth Dmax into the bone along the circumference of the implant hat H; the total volume of bone and/or cartilage to be removed for implanting the implant; and/or the surface area of the implant penetration into the bone.

    Abstract: A method and system for computer assisted orthopedic feedback of at least one surgical object relative a pre-operative plan are disclosed. The pre-operative plan includes a virtual object, which is the virtual representation of the surgical object, and a virtual structure, which is the virtual representation of the patient structure. The method comprises providing the pre-operative plan including planned position and orientation of the virtual object relative to of the virtual structure; obtaining the position of the patient structure based on a surface of the patient structure using a surgical navigation system; obtaining the position of the surgical object using the surgical navigation system; registering the patient structure to the virtual structure and the surgical object to the virtual object; tracking a current position and orientation of the surgical object using the surgical navigation system; and providing feedback of a current position and orientation of the surgical object relative to the planned position and orientation of the virtual object based on the tracked current position and orientation of the surgical object.
