Abstract
A system for creating a patient-specific instrument model for chondral graft plugging comprises a bone model generator for producing a bone/cartilage model of an articular region of a bone from images thereof. A defect geometry identifier identifies a graft geometry from a defect region of said bone/cartilage model. A donor locator locates an autograft at a donor site or identifies an allograft from a database, using said bone/cartilage model and the graft geometry. A patient-specific instrument model generator creates a model of a graft-plugging patient-specific instrument from said bone/cartilage model, and the graft geometry, the graft-plugging patient-specific instrument model comprising a bone/cartilage interface surface shaped as a function of the bone/cartilage model for the at least one graft-plugging patient-specific instrument to be selectively positioned on the bone/cartilage to pose the autograft or the allograft at the defect region.
