Abstract
Systems and processes for tracking anatomy, instrumentation, trial implants, implants, and references, and rendering images and data related to them in connection with surgical operations, for example total knee arthroplasties (“TKA”). These systems and processes are accomplished by using a computer to intraoperatively obtain images of body parts and to register, navigate, and track surgical instruments.

21. A computer system for facilitating a joint arthroplasty procedure on a patient'"'"'s joint, the patient'"'"'s joint including at least one bone, the computer system comprising:
-
(a) an input that receives image data about a structure of the at least one bone; (b) a memory that at least temporarily stores; (i) the image data about the structure of the at least one bone; (ii) reference data about at least one reference related to the structure of the at least one bone; (iii) device data about a first surgical device, wherein the first surgical device is an orthopaedic implant; and (iv) device data about a second surgical device, wherein the second surgical device is a surgical instrument; (c) a processor that accesses the image, reference and device data about the first and second surgical devices at least temporarily stored in the memory and identifies a desired position and orientation of the surgical instrument relative to the at least one bone of the patient based at least in part on the image, reference and device data about the first and second surgical devices; and (d) an output that outputs information about the desired position and orientation of the surgical instrument relative to the at least one bone. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)

44. A computer system for facilitating a joint arthroplasty procedure on a patient'"'"'s joint, the patient'"'"'s joint including at least one bone, the computer system comprising:
-
(a) an input that receives image data about a structure of the at least one bone; (b) a memory that at least temporarily stores; (i) the image data about the structure of the at least one bone; (ii) reference data about at least one reference related to the structure of the at least one bone; (iii) device data about a first surgical device, wherein the first surgical device is an orthopaedic implant; and (iv) device data about a second surgical device, wherein the second surgical device is a surgical instrument; (c) a processor that;
(1) accesses the image, reference and device data about the first and second surgical devices at least temporarily stored in the memory and identifies a desired position and orientation of the surgical instrument relative to the at least one bone of the patient based at least in part on the image, reference and device data about the first and second surgical devices, and (2) determines a mechanical axis or an anatomic axis of the at least one bone using the reference data; and(d) an output that outputs information about the desired position and orientation of the surgical instrument relative to the at least one bone. - View Dependent Claims (45, 46, 47, 48, 49)
