New technology eliminates guesswork in knee surgeries
Operating with a computer-assisted visualization guide consisting of one high-def TV for Dr. Stefan Kreuzer and another for an associate who keeps watch over the software, a robotic arm gently directs the surgeon's hand as he chisels an ever-so-precise chunk from the tip of a patient's arthritis-damaged femur. Should Kreuzer wander off course the least little bit, the computer squawks irritably, then locks him down cold.
