1. A method, comprising:
obtaining bone registration data for a first bone member of a patient and a second bone member of a joint of the patient;
obtaining surgeon-defined laxity data of the joint of the patient;
wherein the surgeon-defined laxity data comprises:
at least one defined laxity location reference point in the joint, and
at least one laxity value with respect to the at least one defined laxity location reference point;
cutting the first bone member during a surgical procedure for an implantation of an implant;
placing a distractor between the first bone member and the second bone member to apply, during at least one movement, a distraction force between the first bone member and the second bone member;
obtaining, during the surgical procedure, patient-specific movement-related data after the first bone member of the joint, the second bone member of the joint, or both, have been put through the at least one movement when the distraction force is applied between the first bone member and the second bone member throughout a continuous range of motions;
utilizing a surgical plan model to obtain a patient-specific intra-operative surgical plan for the implantation of the implant, based at least in part on:
the bone registration data for the first bone member and the second bone member,
the surgeon-defined laxity data of the joint, and
the patient-specific movement-related data;
wherein the patient-specific intra-operative surgical plan comprises at least one surgical cut parameter constrained at least in part by the surgeon-defined laxity data; and
cutting the second bone member of the joint based at least in part on the at least one surgical cut parameter to facilitate the implantation of the implant.
