1. A method of placing an implant to treat a defect associated with an articular surface of a joint of a patient, the method comprising:
receiving first data associated with the articular surface, the first data indicating a surface geometry of the articular surface;
generating, using the first data, a bone model corresponding to bone tissue associated with the articular surface;
defining a geometry of the defect;
generating, using the bone model and the geometry of the defect, an implant model configured to treat the defect;
receiving an implant corresponding to the implant model;
generating an implantation plan for the implant, wherein the implantation plan comprises at least one of a size, a shape, a location, or an orientation of a cavity at the articular surface that is configured to receive the implant;
creating an incision at the joint of the patient;
resecting the articular surface to create the cavity;
placing the implant into the cavity;
prior to closing the incision, using an instrumented probe to map a post-implantation articular surface that is formed at least partially by the implant to create a post-implantation surface map of the articular surface, wherein the post-implantation surface map comprises a post-implantation surface geometry of the articular surface;
receiving healthy bone anatomy data from a database;
comparing the post-implantation surface map with the healthy bone anatomy data to assess a congruency of the implant with a portion of the articular surface surrounding the implant to determine, whether a modification to the implant is needed for the implant to be congruent with the articular surface; and
when it is determined that the modification to the implant is needed for the implant to be congruent with the articular surface, shaving or planing an implant articular surface of the implant so that the implant is congruent with the articular surface of the joint.
