Computer-Assisted Surgery (CAS) is a technology that has been adapted for a variety of surgical procedures and is similar to GPS in that it provides turn-by-turn directions to navigate your surgeon to customize the surgery to your specific anatomy, regardless of age or gender. The data obtained by the computer system enables your surgeon to position the implant with greater accuracy, improving the function of the joint replacement.
More Precise Joint Alignment
The computer maps your anatomy and provides real time information, which helps your surgeon implant into an accurately aligned position. A well-aligned hip or knee replacement is less likely to dislocate and has greater longevity.
Customized for Your Anatomy
Computer-navigated surgery takes your individual shape and size into account to ensure each replacement is as accurate as possible.
Enhanced Surgery Outcomes
Computer-navigated systems do not perform the operation. They are a tool used to enhance the outcome of total joint replacement surgeries.
OrthoPilot Navigation System
OrthoPilot is a computer assisted navigation system which helps the surgeon to perform operations on both the hip and knee with a high degree of accuracy and increased reliability. It is a pure navigation system and shows the surgeon where the important anatomical landmarks are located. The doctor maintains control over the implantation procedure throughout the operation, and can proceed manually at any time should this become necessary.
Benefits of the OrthoPilot Navigation System include:
- Helps the surgeon to achieve optimal alignment of the implant which can:
- Increase implant longevity by decreasing uneven wear
- Increase stability and range of motion
- Decrease the risk of dislocation and revision surgery
- Eliminates excess exposure to radiation by removing the need for X-rays and CT scans
- Proven success in more than 300 publications
- Used in more than 285,000 cases
- Less invasive surgery due to enhanced visualization, which has many benefits including:
- Reduced blood loss, decreased need for transfusion
- Faster return to a better quality of life
- Shorter hospital stay
- Improved implant sizing and positioning reliability
- Large orthopaedic range: knee, hip and sports medicine procedures.
How OrthoPilot works?
The OrthoPilot is made up of an infrared camera, a computer screen, transmitters, and a mobile marker instrument. The infrared camera is used to pick up information off the transmitters attached to the instrumentation to collect positional data. The unit has a computer with a touch screen used to enter additional data. The software is able to calculate a three dimensional image from the positions of the transmitters.
Transmitters are positioned on the patient’s body to help guide the surgeon throughout surgery. The position of the transmitters is sent to an infrared camera mounted on the OrthoPilot. Information is relayed to the computer and used to display real-time images of the anatomy along with measurements needed to make crucial decisions throughout the surgical procedure.
Why use OrthoPilot?
Proper positioning of the implant is critical for a successful surgery. In traditional surgeries, surgeons manually measure bone length, angles, and ligament tensions. A miscalculation of any of these measurements can undermine the procedure and possibly alter the results of the surgery. Misalignment of the implant can result in increased wear on the prosthesis itself.
In a study of 821 patients, 3 of every 10 who received implants through traditional methods were found to have an implant out of optimal alignment by more than 3 degrees and 1 of 10 was out of alignment by 5 degrees. However, in surgical procedures supported by OrthoPilot, patients enjoyed up to a 300% improvement in knee implant alignment accuracy.
The OrthoPilot can be used to improve accuracy in the following procedures:
- Total Knee Replacement
- Partial Knee Replacement
- Revision Knee Replacement
- Total Hip Reconstruction
- ACL Reconstruction
- High Tibial Osteotomy
