Abstract
In the surgical replacement of the knee joint, accurate alignment of prosthetic components with respect to the mechanical axis of the leg is essential to the mobility and longevity of the joint. Such alignment cannot easily be done during surgery because the long bones are largely obscured by tissue. An integrated system has been developed that allows the surgeon to more accurately place implant components during total knee surgery. A graphic computer displaying 3-dimensional CT data of the patient's knee is used to perform more informed and accurate preoperative planning. In the operating room, a robot and specially designed fixturing aid the surgeon in performing the bone resections as determined in the preoperative plan. Crucial to the accuracy of this system is the rigid immobilization of the involved bones and the robot's ability to determine their exact locations in space. The rationale and an overview of this system are presented as well as a discussion of some of the technical issues that have arisen.
