Systems and methods for customizing interactive virtual boundaries

1. A method for customizing an interactive control boundary based on a patient-specific feature, comprising:

identifying a reference feature associated with a virtual implant model;

determining an intersection between the identified reference feature and a virtual model associated with an anatomy of the patient; and

generating a virtual boundary based on the determined intersection between the identified reference feature associated with the virtual implant model and the virtual model associated with the anatomy of the patient.

2. The method of claim 1 , further including displaying the generated virtual boundary, the virtual model associated with the anatomy of the patient, and the virtual implant model on a display.

3. The method of claim 1 , wherein the virtual implant model includes a virtual model of a tibial prosthetic base, wherein the reference feature includes a bottom surface of the tibial prosthetic base.

4. The method of claim 1 , wherein determining the intersection between the identified reference feature and the virtual model includes:

identifying an anatomic feature of the patient's anatomy on the virtual model;

estimating an intersection between the reference feature associated with the virtual implant model and the anatomic feature on the virtual model; and

generating the virtual boundary based on the estimated intersection between the reference feature and the anatomic feature.

5. The method of claim 1 , wherein the virtual implant model corresponds with a prosthetic implant and the reference feature associated with the virtual implant model comprises a three-dimensional virtual representation of the surface of the prosthetic implant that abuts the patient's anatomy.

6. The method of claim 1 , wherein generating the virtual boundary comprises:

identifying an area of the virtual model associated with the patient's anatomy that overlaps with an area associated with the virtual implant model; and

virtually resecting the determined overlapping area of the virtual model.

7. The method of claim 1 , further comprising:

receiving a signal indicative of a user-defined modification to the generated virtual boundary; and

modifying the generated virtual boundary based on the received signal.

8. The method of claim 1 , further comprising:

receiving computed tomography (CT) data associated with the patient's anatomy; and

generating the virtual model associated with the patient's anatomy based on the CT data.

9. The method of claim 1 , further comprising:

generating the virtual model associated with the patient's anatomy utilizing an imageless system.

10. A computer-assisted surgery system comprising:

a display;

an input device configured to receive data input by a user;

a processor, operatively coupled to the input device and the display and configured to:

identify a reference feature associated with a virtual implant model;

determine an intersection between the identified reference feature and a virtual model associated with an anatomy of the patient;

generate a virtual boundary based on the determined intersection between the identified reference feature associated with the virtual implant model and the virtual model associated with the anatomy of the patient; and

display the generated virtual boundary and the virtual model associated with the anatomy of the patient on the display.

11. The computer assisted surgery system of claim 10 , wherein the processor is further configured to display the virtual implant model on the display.

12. The computer assisted surgery system of claim 10 , wherein the virtual implant model includes a virtual model of a tibial prosthetic base, wherein the reference feature includes a bottom surface of the tibial prosthetic base.

13. The computer assisted surgery system of claim 10 , wherein determining the intersection between the identified reference feature and the virtual model includes:

identifying an anatomic feature of the patient's anatomy on the virtual model;

estimating an intersection between the reference feature associated with the virtual implant model and the anatomic feature on the virtual model; and

generating the virtual boundary based on the estimated intersection between the reference feature and the anatomic feature.

14. The computer assisted surgery system claim 10 , wherein the virtual implant model corresponds with a prosthetic implant and the reference feature associated with the virtual implant model comprises a three-dimensional virtual representation of the surface of the prosthetic implant that abuts the patient's anatomy.

15. The computer assisted surgery system of claim 10 , wherein generating the virtual boundary comprises:

identifying an area of the virtual model associated with the patient's anatomy that overlaps with an area associated with the virtual implant model; and

virtually resecting the determined overlapping area of the virtual model.

16. The computer assisted surgery system of claim 10 , wherein the processor is further configured to:

receive a signal indicative of a user-defined modification to the generated virtual boundary; and

modify the generated virtual boundary based on the received signal.

17. The computer assisted surgery system of claim 10 , wherein the processor is further configured to:

receive computed tomography (CT) data associated with the patient's anatomy; and

generate the virtual model associated with the patient's anatomy based on the CT data.

18. The computer assisted surgery system of claim 10 , wherein the processor is further configured to:

generate the virtual model associated with the patient's anatomy utilizing an imageless system.
