Paragraph Number

199

Referring to FIG. 11E, in one embodiment, anatomical data about the patient can be used to define other structures of the resection guide 1020 or other patient specific instruments. For example, anatomical data about the patient that can be captured in the patient imaging data (e.g., due to the fidelity of the technology providing the patient imaging data) can be used to define how deep one or more resection features 1022 are. Controlling the depth of the resection features 1022 can be used to manage how deep a surgeon’s cutting instruments can reach within the resection features 1022. Managing a depth for one or more resection features may be referred to as defining a patient specific height for the resection guide 1020. In one embodiment, the patient imaging data is used to define a desired cutting depth. This depth can be used to report a depth marking that a surgeon should watch for on an edge of the cutting tool that indicates how deep the cutting tool is. The preoperative plan provided according to the present disclosure can indicate this desired cutting depth. During the surgical procedure, a surgeon can watch for this depth as the resection is being performed.
