1. Open the sterile Drape package

Perform a sterile transfer of the Drape from the outer packaging. Discard the protective packaging around the Drape.

2. Prepare the Drape

Lay the folded Drape flat on the sterile table. Identify the lens area and the handle end of the Drape. Gently release the folded section in the middle of these ends by pulling each side in opposite directions.

3. Create pathway inside the Drape

With one hand, pick up the Drape from the cardboard backer end. With the other hand, gently insert it inside the Drape to clear a pathway for the Camera.

4. Check Camera channel

From the cardboard end of the Drape, visually confirm that the Camera pathway extends through to the plastic camera window on the opposite end.

5. Insert Camera

A non-sterile OR team member can now gravity feed the Camera into the prepared drape channel

6. Camera Positioning

The sterile person pulls the Camera and cord through the Drape. Carefully coil and organize the draped cord to prevent tangling. Based on the procedural requirements, proceed to the normal steps for placing the Camera Shroud (HIP) or Camera Mount (KNEE).

Three potential lights (blue, green and yellow) can be shown at top of the Camera. When the Camera is first connected all three lights will illuminate in succession. The blue Power Indicator light will turn on when the Camera is connected, and the Intellijoint Application is launched.

The Camera Disconnected Indicator appears in the top right corner of the Application if the Camera disconnects from the Workstation. It can appear on its own or as an overlay on top of the Tracking Indicator.

If you are noticing persistent Camera Disconnected Indicator, try unplugging the Camera’s USB and plugging it back into the port.

If the issue persists, when the time is appropriate, exit the application and shut down the system.  If you are on HIP 2.11 and KNEE 1.6.7 or later, the case will autosave. When the computer is turned back on, click back into the application and previous workflow. Select “Continue Last Case” when prompted.

If the Camera Connection Lost module pops up, check to make sure the Camera is connected to the Workstation USB port. If it is already connected, try unplugging the Camera’s USB and plugging it back into the port.

The Lateral Platform workflow uses the Femur Platform on the femur to measure leg length and offset changes. The Lateral Ellipse Disc workflow uses the Ellipse Disc on the femur to measure leg length and offset changes.

If you are unsure which workflow to choose, consult with the surgeon.

Pressing the green button on the Camera will capture the registration step, measurement, or progress the user forwards in the Workflow when applicable.

Pressing and holding the green button on the Camera will allow the user to skip the screen when applicable.

Pressing and holding the “X” button on the Camera will allow the user to return to the previous screen.

After a registration step has already been captured, the user can press the green button on the Camera again to “Overwrite” the previously recorded registration.

If the capture is resetting, ensure the Tracker and Camera are fully seated during the capture. If the Tracker is experiencing soft-tissue interference, consider placing additional retractors to ensure a smooth capture.

The capture may also be resetting if the femoral head is translating within the acetabulum. Ensure the femoral head is properly rotating within the acetabulum during the capture.

If the capture is stalling, ensure a sufficiently large angular range of motion is covered in all directions. Consider flexion/extension, internal/external rotation and abduction/adduction.

If a valid native hip center is impossible to obtain, because of an extremely diseased hip joint, Baseline Hip Center captured can be skipped. If Baseline Hip Center is skipped, the user will still be able to obtain changes in leg length and offset, but changes in hip center measurements will not be shown.

If the capture is resetting, ensure the operative leg is not moving while capturing the Disc trace. Ensure the Camera is fully seated during the capture and that the Probe is not experiencing soft-tissue interference. If the Probe is experiencing soft-tissue interference, consider placing additional retractors to ensure a smooth capture.

Ensure the Tracker is properly seated on the V-block. The V-block must be on a section of the cup impactor that is coaxial with the acetabular axis of the cup.

Open a new Intellijoint HIP tray and Intellijoint HIP procedure pack to obtain a new Tracker and set of Spheres.

Open a new Intellijoint HIP tray to obtain a new V-block. Cup positioned can still be captured after it has been implanted using the Acetabular Reference Plane, which requires the Tracker and Probe.

Open a new Intellijoint HIP tray to obtain a new Probe. Re-calibrate the new Probe using the Probe Calibration feature in the Toolbox.

If the Femur Platform/Ellipse Disc is no longer stable or comes off after the femoral neck cut has been made, the user should discontinue use for leg length and offset. The user can still capture cup position measurements.

If the neck cut has not been made, reposition the Femur Platform/Ellipse Disc, ensuring proper bony fixation and recapture Baseline Leg Length and Baseline HCOR (when desired) steps.

If you believe that you have selected the incorrect hip side, you can check your selection by hitting the square button on the Camera to access the Toolbox. The Tracking tab will display the hip selection.
