Computer-Assisted Surgery
Cutting Edge Technology for Joint Replacements
Computer-assisted total joint replacement is a surgical procedure that offers the ability to accurately align your new joint. Accurate alignment is important to the overall function of your new joint. This surgical navigation technology requires tracking devices that collect and send information to provide a comprehensive understanding of your joint mechanics before finalizing the joint procedure. Armed with this information, the surgeon can make intraoperative adjustments within a fraction of a degree, helping to ensure your new joint has the strength, stability, and range of motion needed for a successful replacement.
What Generally Happens During the Surgery
During computer-assisted total joint replacement surgery, the navigation system aids the surgeon in showing him or her where to remove the diseased bone tissue and cartilage from the joint. The healthy parts of the joint are left intact. Then, the surgeon replaces the diseased bone with new, artificial parts. The new joint is positioned and placed in alignment to your true anatomy with information received from the infrared instruments and camera.
Orthopedic navigation technology is similar to directional tracking systems used in cars and ships – it is, in effect, a global positioning system (GPS) for the surgeon. Infrared sensors placed in the operating room act like satellites constantly monitoring the location of markers and instruments placed along a patient’s anatomy. Precise alignment is an important factor that may reduce joint wear and extend the life of the implant.
