1. A system for correcting an osteochondral defect, the system comprising:
a tracking system comprising:
a probe having one or more probe tracking arrays, and
one or more patient tracking arrays attached to a joint of a patient, wherein the tracking system is configured to detect a plurality of locations of the one or more probe tracking arrays and the one or more patient tracking arrays;
one or more processors; and
a non-transitory, computer-readable medium storing instructions that, when executed, cause the one or more processors to:
receive the plurality of locations from the tracking system;
generate, based on the plurality of locations, surface data related to an articular surface of a bone of the joint;
define, based on the surface data, an outer boundary enclosing the osteochondral defect to designate a defect surface;
generate, based on at least the surface data, a 3D healthy bone model that does not include the osteochondral defect;
generate, based on at least the 3D healthy bone model and the outer boundary, a 3D implant model corresponding to the defect surface; and
output the 3D implant model to a secondary device.
