摘要：
Aspects of the disclosure involve a method of generating resection plane data for use in planning an arthroplasty procedure on a patient bone. The method includes: obtaining patient data associated with at least a portion of the patient bone, the patient data captured using a medical imaging machine； generating a three-dimensional patient bone model from the patient data, the patient bone model including a polygonal surface mesh； identifying a location of a posterior point on the polygonal surface mesh； creating a three-dimensional shape centered at or near the location； identifying a most posterior vertex of all vertices of the polygonal surface mesh that are enclosed by the three-dimensional shape； using the most posterior vertex as a factor for determining a posterior resection depth； and generating resection data using the posterior resection depth, the resection data configured to be utilized by a navigation system during the arthroplasty procedure.
