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 computer-implemented method including positioning at least one sensor within a joint of a patient; receiving, by a processor, a first data set representing a first series of reaction forces within the joint while the joint is moved through a range of motion; receiving, by the processor, a second data set representing a second series of reaction forces within the joint while the joint is moved through the range of motion while a first trial implant is attached within the joint; calculating, by the processor, a difference between the second data set and the first data set; and providing, by the processor, an instruction based on the difference, the instruction including either an instruction to select a second trial implant if the difference exceeds a threshold, or an instruction to proceed with an actual implant matching the first trial implant if the difference does not exceed the threshold.
