Last fall, Phillip Morris, 64, of Tunnel Hill, Ill., couldn’t walk across a parking lot without experiencing severe knee pain. With no history of arthritis, he knew that something serious had to be wrong.

During a visit to orthopedic surgeon Ted Jefferson, D.O., a simple X-ray showed that the tendon in his knee was worn, causing his bones to rub against one another. He needed a total knee replacement.

“Mr. Morris was a perfect candidate for computer-assisted surgery,” said Dr. Jefferson. “This new approach to knee replacement surgery is minimally invasive and enables better precision and accuracy during surgery.”

Dr. Jefferson said the onscreen imaging of computer-assisted surgery not only guides surgeons in difficult-to-see areas, but also relays specific measurements not previously available, gives precise data on the patient’s specific anatomy and allows adjustments within one millimeter and one degree of accuracy.

The surgery is performed through a five- to six-inch incision, causing minimal muscle trauma and allowing the patient to fully extend his legs. The knee’s anatomy is entered into the computer, which calculates the best position for accurate alignment of the knee replacement. This helps surgeons avoid problems, such as loosening of the tendon and accelerated wear. It helps patients recover more quickly by allowing them to become more active sooner.

Morris said the benefits of computerassisted surgery were remarkable. “I experienced a less visible scar, less pain after surgery and a faster recovery process,” said Morris. “Now I can resume my daily routines, pain-free.”
