Abstract: A kit includes a distractor, a plurality of trial elements, and at least one sensor. The distractor is configured to separate a first bone from a second bone by adjusting the distance between a first member and a second member, and is configured to receive at least one sensor in the first portion. Each of the trial elements corresponds to one of a plurality of surgical implants, is configured to be temporarily coupled to the second bone so as to evaluate suitability of the corresponding one of the plurality of surgical implants for implantation, and is configured to receive at least one sensor. The at least one sensor is configured to be received in the distractor or one of the trial elements, and is configured to record a magnitude of a force, a direction of application of a force, a pressure mapping, or a location of application of a force.

Abstract: A surgery-facilitating system and method include a controller, a first tracker positioned on a first member of a joint, and a second tracker positioned on a second member of the joint. A first anatomical entity of the first member and a second anatomical entity of the second member are tracked using the first and second trackers to generate in the coordinate system, pre-operative kinematic data of the joint during a first movement of the joint, intra-operative kinematic data of the joint during a second movement of the joint, and post-operative kinematic data of the joint during a third movement of the joint. A surgical plan is generated for the surgical procedure of the subject based at least in part on the pre-operative kinematic data, the intra-operative kinematic data, or both, of the joint in the coordinate system.

Abstract: A method includes receiving by a controller, a surgeon-specific surgery profile for an implantation of an implant into a joint, implant profiles, a patient-specific post-surgery desired functional profile of the joint after the implantation, and bone registration data for a first bone member and a second bone member of a patient are inputted into a surgical plan model to generate a surgical plan. The surgical plan model is designed to achieve the patient-specific post-surgery desired functional profile based at least in part on a plurality of dependencies between a plurality of surgical parameters, the implant profiles, at least one functional parameter representative of the expected functional performance of the joint, and movement-related data of the joint. The surgical plan is outputted on a graphical user interface (GUI) on a surgery assistant device to facilitate the implantation.
