Abstract
A computer-implemented method for creating an activity-optimized cutting guides for surgical procedures includes receiving one or more pre-operative images depicting one or more anatomical joints of a patient, and creating a three-dimensional anatomical model of the one or more anatomical joints based on the one or more pre-operative images. One or more patient-specific anatomical measurements are determined based on the three-dimensional anatomical model. A statistical model of joint performance is applied to the patient-specific anatomical measurements to identify one or more cut angles for performing a surgical procedure. A patient-specific cutting guide is created that comprises one or more apertures positioned based on the one or more cut angles.
Claims20
A system for creating an activity-optimized cutting guide for a surgical procedure, the system comprising:
- one or more processors;
- and
- a non-transitory, computer-readable medium storing instructions that, when executed, cause the one or more processors to:
- determine, based on pre-operative image data, one or more patient-specific anatomical measurements associated with an anatomical joint of a patient,
- apply a statistical model of joint performance to the one or more patient-specific anatomical measurements, wherein the statistical model uses one or more transfer functions,
- identify one or more cut angles for performing a surgical procedure based on the applied statistical model,
- generate a model of a patient-specific cutting guide based on the one or more cut angles, and
- output the model to a computer-readable storage device.
