A method for guiding bone removal during a surgical procedure includes receiving a two-dimensional image of at least a portion of a joint during the surgical procedure, determining an alignment of a pre-generated three-dimensional model of the at least a portion of the joint with the two-dimensional image based on one or more features in the two-dimensional image that are associated with the at least a portion of the joint, wherein the pre-generated three-dimensional model comprises a representation of planned bone removal, generating an overlay image based on the determined alignment, the overlay image comprising an overlay of at least a portion of the representation of planned bone removal on the two-dimensional image, and displaying the overlay image to guide bone removal during the surgical procedure.

Systems and methods for visually guiding bone removal during a surgical procedure on a joint

Disclosed are computer visual guidance systems for guiding surgeons through arthroscopic debridement of bony pathologies, including by automatically generating annotations relating to characteristics of bony pathology in an image. The annotation may be generated in accordance with a determination as to whether a femoral head of the bony pathology is endospherical or exospherical. The annotation may be generated in accordance with a mathematical model created based on anatomies of subjects other than the patient. Further disclosed is a user interfaces for guiding a surgeon through arthroscopic debridement of a bony pathology, wherein intraoperative images are displayed simultaneously with a preoperative plan comprising interactive three-dimensional models of an anatomical feature of a patient. Further disclosed is a user interface for guiding a physician in categorizing images of a patient, wherein the interface comprises an image viewing window and an interactive checklist for different image categories to be captured.
