Robotic Primary and Revision THA for the Femoral Side
Robot-assisted THA for femoral side is one of the oldest appreciations of robotics in orthopedic surgery. The first active robotic system, ROBODOC, has been used in many countries. Originally, it utilized pin-based registration system and required locator pin implantation in the patient femur before THA. Subsequently, non-pin-based surface registration technique was developed, which eliminated the need for pin implantation and pin-related complications. Besides the function of femoral milling during primary THA, this system can also selectively remove bone cement from the femoral canal during revision THA. Although one study shows a higher revision rate of robotic femoral surgery than a conventional technique, many studies show accurate femoral preparation, same or slightly better postoperative function, better alignment of the stem, less fat embolism, less stress shielding, and a lower incidence of femoral fracture by using the robot than conventional techniques.
