Summary
The Robodoc Pinless System was introduced at BGU Frankfurt in mid- 1998. In the preoperative planning phase, using the 3-D CT data, the surgeon places a model of the implant into position and the Orthodoc determines the cut path for Robodoc. The surgeon then creates a 3-D surface model that is used intraoperatively for pinless registration. In the operating room, the points are compared to the surface model created on the Orthodoc to register the robot to the femur position. Using the pinless system, 95%–98% of all patients can be operated on. Exclusion criteria are severely disfigured posttraumatic cases, revision cases, and cases with a nontitanium implant in the opposite leg, because there are too many metal artifacts in the CT scan. The number of pinless procedures has risen steadily since its introduction. The major advantages of the pinless procedure are that only one operation is needed. Postoperative knee pain is eliminated in most cases, and costs per surgery are reduced. Surgical time and radiation exposure are the same as in the pin-based system, and system accuracy and reliability are equal to the pin-based system.
