SYSTEMS AND METHODS FOR JOINT REPLACEMENT
Systems and methods for joint replacement are provided. The systems and methods include a surgical orientation device and at least one orthopedic fixture. The surgical orientation device and orthopedic fixtures can be used to locate the orientation of an axis in the body, to adjust an orientation of a cutting plane or planes along a bony surface, to distract a joint, or to otherwise assist in an orthopedic procedure or procedures.
1 . An interactive user interface for aiding a user in performing an orthopedic procedure, wherein the user interface is displayed on a display associated with a surgical orientation device configured to monitor the orientation of the surgical orientation device in a three-dimensional coordinate reference system and wherein the user interface is configured to perform acts comprising:
showing the user steps to be performed in the identified orthopedic procedure; and
guiding the user in performance of the steps; wherein guiding the user comprises:
displaying one or more instructive images related to a first step to be performed in the identified orthopedic procedure;
prompting the user to press a user input after performing the first step of the identified orthopedic procedure;
receiving a confirmation from the user that the first step of the identified procedure has been performed; and
displaying one or more instructive images related to the second step to be performed in the identified orthopedic procedure.
2 . The interactive user interface of claim 1 , wherein guiding the user further comprises:
receiving a user input identifying one or more reference orientations of the surgical orientation device;
confirming to the user whether the user input has been received;
storing orientation data corresponding to the one or more reference orientations; and
displaying a visual indicator of a current orientation of the surgical orientation device relative to the stored orientation data.
3 . The interactive user interface of claim 1 , wherein the instructive images comprise graphical user interface (“GUI”) images.
4 . The interactive user interface of claim 1 , wherein the visual indicator comprises a GUI image.
5 . The interactive user interface of claim 1 , wherein the visual indicator comprises an angle measurement corresponding to the current orientation of the surgical orientation device relative to the stored orientation data.
6 . The interactive user interface of claim 4 , wherein the visual indicator comprises a bubble level GUI image corresponding to the current orientation of the surgical orientation device.
7 . A monitoring system for monitoring an orientation of a surgical orientation device having an associated three-dimensional coordinate reference system during an orthopedic procedure, the orientation system comprising:
a display having a window; and
an on-screen graphic, displayed in the window and representing one or more orientation measurements corresponding to an orientation of the surgical orientation device about one or more axes of the three-dimensional coordinate reference system, the one or more orientation measurements generated by a processor.
8 . The monitoring system of claim 7 , wherein the on-screen graphic comprises a graphical user interface (“GUI”) image.
9 . The monitoring system of claim 7 , wherein the orthopedic procedure comprises a total knee arthroplasty procedure, and wherein the on-screen graphic comprises a display of one or more angle measurements corresponding to an offset from a flexion-extension angle or a varus-valgus angle of a mechanical axis of the knee joint.
10 . The monitoring system of claim 7 , wherein the one or more orientation measurements are relative to a reference orientation stored in the surgical orientation device.
11 . The monitoring system of claim 7 , wherein the on-screen graphic comprises alphanumeric text or symbols.
12 . The monitoring system of claim 8 , wherein the GUI image comprises a bubble level indicator.
