David Johnson, M.D., a Board-Certified Orthopedic Surgeon at West Tennessee Bone & Joint Clinic, recently performed the first ligament-sparing total knee replacement surgery in Tennessee at Jackson-Madison County General Hospital.
According to a press release, the knee implant allows for a greater range of motion, allowing patients to resume their active lifestyles.
Unlike traditional total knee implants, the JOURNEY II XR Total Knee Implant from Smith & Nephew uses a specially designed U-shaped tibial base plate. It allows a patient’s healthy anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) to remain in place after surgery. These ligaments help provide natural stability and support to the knee and are often removed to accommodate the base plates used in other total knee implants.
The JOURNEY II XR implant also features an anatomically shaped femoral component and two plastic inserts. They are designed to work together to reproduce the original internal shapes and forces of the natural knee as it goes through its full range of motion. The advanced implant also features the proprietary VERILAST Technology, a unique combination of materials designed to reduce implant wear.
“This new implant is the latest advance in knee replacement surgery,” said Dr. Johnson. “By sparing the ligaments that provide support during motion, patients can achieve a more natural feeling function with their knee. In general, patients can return to a higher level of activity faster and with reduced pain.”
Along with the advances offered by the implant itself, orthopedic surgeons at West Tennessee Bone & Joint Clinic in Jackson perform the JOURNEY II XR surgery using Smith & Nephew’s NAVIO Surgical System.
With the NAVIO surgical system, the surgeon collects and registers patient-specific anatomic data, which the system uses to create a real-time 3D model of the patient’s knee. This layer of planning is designed to enable accurate implant placement and ligament balancing to achieve optimal patient outcomes. The NAVIO system does not require a pre-operative CT-scan.
“Robotic-assisted total and partial knee replacements are associated with decreased pain and improved early functional recovery,” Dr. Johnson said. “The hand-held NAVIO Surgical System offers two important benefits for people undergoing a knee replacement procedure – greater accuracy and no exposure to CT radiation.”
West Tennessee Bone & Joint Clinic P.C. is the largest and most comprehensive orthopedic practice group between Memphis and Nashville. With the mission of “Keeping You Active,” it provides a complete array of expert care that includes diagnosis, imaging, surgery, interventional pain management, physical and occupational therapy and an ambulatory surgery center.
