New Technology Benefits Spine Surgery Patients

KOC's spinal surgery specialists, Dr. Paul Johnson and Dr. Kimbro Maguire, Jr., are the first physicians in Knoxville to use the new, state-of-the-art surgical equipment from Medtronic at the Center for Advanced Orthopedics at Physicians Regional Medical Center. The equipment allows them to visualize anatomy in 3D during spinal surgery. This advancement has the potential to reduce the need for repeat surgeries, and for many patients, it also may mean smaller incisions, faster recovery times and improved results. Learn More.
