Dr. James Chow performs Arizona hospital's 1st knee replacement with new robot


Abrazo Scottsdale Campus' first robotic knee replacement with Smith+Nephew's Cori system was completed by James Chow, MD, who helped design the device, according to Scottsdale Progress.

The handheld system uses artificial intelligence to help surgeons with unicompartmental knee replacement and total knee replacement procedures.

Dr. Chow used Cori to perform an anterior cruciate ligament preserving total knee replacement at the Phoenix hospital in July.

Cori differs from competing robotic devices in three areas: it's smaller, doesn't rely on preoperative imaging and features a handheld tool surgeons can use with their own techniques.

Cori relies on reflective discs that bounce infrared light to cameras equipped within the tool to serve as a tracker. After disc placement, the tool scans the surface of the bone that needs to be removed. The tool recognizes the parameters of the cutting area and shuts off when outside of those parameters.
