Abstract: A method for improving the development of an initial surgical plan includes receiving input information, developing an initial surgical plan based upon the input information, and allowing a user to customize the initial surgical plan by providing input related to modifications to the initial surgical plan. The method further includes storing information related to the modifications to the initial surgical plan and using the stored information to develop a subsequent initial surgical plan based on the modifications.

Abstract: A method for verifying a spatial registration of an anatomical region is provided. The method may track a spatial pose of at least one checkpoint defined within the anatomical region, track a spatial pose of a probe tip in proximity to the anatomical region at the checkpoint, map a spatial proximity between the probe tip and the anatomical region onto a visual representation of the anatomical region based on the tracked spatial poses, quantify a deviation between the mapped spatial proximity and an actual spatial proximity in response to a verification request where the verification request is initiated by a user and indicative of the actual spatial proximity between the probe tip and the anatomical region, and generate a graphical index indicative of a degree of accuracy of the spatial registration of the anatomical region based on the quantified deviation.

Abstract: In one embodiment of the present invention, a method is provided for assisting cartilage diagnostic and therapeutic procedures and includes the steps of acquiring 3D osteocartilaginous parameters by using multimodal 3D tracked devices; incorporating these parameters into a volumic anatomic osteocartilaginous model from which a bone tracking virtual real-time environment is built; three-dimensionally computing an osteocartilaginous quality score from this multiparametric 3D osteocartilaginous model; providing real-time navigation in this 3D virtual environment in order to make ongoing therapeutic assessments and adjustments; and updating steps 1 to 3 according to the performed therapy. It will be appreciated that the above steps are compatible with arthroscopic procedures involving cartilage.

Abstract: A method for guiding a user during surgical planning includes receiving input information; applying an algorithm to the input information to develop an initial surgical plan; and guiding a user by providing a plurality of suggested actions to the user. If the user performs the plurality of suggested actions, the plurality of suggested actions leads the user to the initial surgical plan. The user has an option to deviate from one or more of the plurality of suggested actions by performing non-suggested actions. Deviation from one or more of the plurality of suggested actions leads to development of a final surgical plan that is different from the initial surgical plan.

Abstract: A computer-assisted orthopedic surgery system includes a device for generating a three dimensional geometrical surface model of a first bone and a database containing three 3 dimensional implant models of a plurality of available implants. The system includes a computer that is configured to permit a user to select from the database a first implant and display on a screen the three dimensional implant model of the first implant. The computer superimposes on the screen the implant model on top of the model of the first bone such that the two models are visually identifiable from one another.

Abstract: A computer assisted orthopedic surgery system for ligament graft reconstruction includes a system for obtaining data indicative of a location for ligament graft placement with respect to at least a first bone and a second bone. The system includes a position determining device that is capable of tracking the relative movements of the first and second bones using reference bodies that are attached to the first and second bones and a pointer that has a tip for contacting a surface of at least one of the first and second bones to capture one or more reference points. The system further includes a computer that is configured to determine and track intraoperative positions of the reference bodies and the pointer and to provide isometric and impingement data for a ligament graft placement based on a realistic simulation of a trajectory of a deformable ligament graft.

Abstract: A method for performing computer-assisted orthopaedic surgery includes the steps of: (1) producing and displaying three-dimensional geometrical models of first and second bones, the first and second bones forming a joint; (2) identifying a zone of impingement between the first bone and the second bone on at least one of the bones; and (3) generating and displaying a color map of at least one surface of at least one bone, the at least one surface being within the zone of impingement, the color map including different colors representing different depths of bone to be removed in order to achieve an increased range of motion between the first and second bones.
