7. A method comprising:
preparing a joint of a patient for a surgical procedure, the joint connecting a first bone to an object and the joint having a joint center of rotation;
coupling together the object and a target of an electronic guidance system configured to generate relative poses between the first bone and the object using the target, the target coupled together with the object via a corkscrew tool;
rotating the corkscrew tool about the joint center of rotation to rotate the object about the joint center of rotation to provide a first articulation data set comprising poses from the electronic guidance system to a computing unit configured to calculate the joint center of rotation for the joint responsive to the first articulation data set to guide the surgical procedure;
performing at least a partial reconstructing of the joint;
mating an implant interfacing tool with the joint as at least partially reconstructed, the interfacing tool coupled to the target; and
rotating the implant interfacing tool coupled to the target and using the electronic guidance system and the computing unit to determine a second joint center of rotation for the joint as at least partially reconstructed to guide the surgical procedure.
