SURGEONS AT MAURY REGIONAL AMONG THE FIRST IN THE STATE TO USE PATIENT-CUSTOMIZED INSTRUMENTS FOR KNEE REPLACEMENT

COLUMBIA, Tenn.— Drs. Scott McCall and Fredrick Wade, orthopedic surgeons on the medical staff at Maury Regional Medical Center (MRMC), are among the first in Middle Tennessee to utilize a remarkable system to build surgical instruments for knee replacement that are customized for a patient’s unique knee anatomy.

“While every person’s knee joint has subtle differences in shape and contour, traditional surgical instruments used in knee replacement surgery are often one-size-fits-all. In the past, a surgeon would use alignment instruments during the procedure in order to achieve the proper placement of the implant,” said McCall, who performed his first procedure on March 23, 2010.

VISIONAIRE Patient Match technology is a system that uses a patient’s MRI and X-ray images to design and build surgical instruments used in his or her knee replacement surgery. These images are uploaded into software that maps the patient’s anatomy and re-establishes true alignment. Specific cutting blocks and instruments are created that match the outer shape and contours of the bones in the patient’s knee joint. In addition, the software calculates the proper joint implant size.

McCall and Wade have been specially trained to use this technology and indicate that in their experience these unique surgical tools help to achieve greater precision and improve recovery time by reducing the trauma and blood loss in surrounding tissue. Not only does the VISIONAIRE system eliminate multiple steps from the surgery, thus reducing time under anesthesia, but an implant placed with this computer-guided precision has a reduced risk of misalignment that can cause it to wear out before its time.

“This technology is truly groundbreaking,” said Wade. “Because the technology delivers pre-sized and pre-aligned instruments, I have more confidence in the accurate placement of the implant while my patients benefit from a simplified procedure.”
