A New Chapter in Knee Implants

kneeappointmentDr. Stickney, a Kirkland orthopedic surgeon, is a knee expert specializing in new knee surgery procedures, knee reconstruction surgery, sports medicine, and more.

New developments in biomedical engineering and robotics have recently opened a new chapter in high-performance knee implants with the creation of the JOURNEY II XR Active Knee System, which combines an implant designed to restore the stability and natural motion of the human knee with low-friction materials that may help extend the longevity of the implant itself. We are proud to be offering this new product to our patients.

Conventional Knee Implants
All knee implants are faced with the challenge of mimicking the normal swing-and-rotate motion of the knee while making sure the joint remains stable and has durability after surgery. Conventional knee implants have attempted to recreate this natural, fluid motion of the knee with a rotating platform or plastic insert design that allows flex and rotation. Unfortunately, both of these options force the muscles around the patient’s joint to work harder as they adjust to the joint’s new pattern of movement. The anterior cruciate ligament and sometimes the posterior cruciate ligaments are removed with conventional Knee designs. These ligaments aid in position sense or proprioception. There have been many different designs of the plastic insert to replicate the function of these ligaments. The JOURNEY II XR is designed to keep the ligaments and build the knee around them. This does make the technical aspect of inserting the knee more complicated. It will also provide a much more natural feeling knee with activity.

The JOURNEY II XR Knee Implant pays attention to anatomical detail, more accurately replicating the true anatomy of the knee. With an anatomically molded femoral component (bottom of the thigh bone) and two plastic inserts, the JOURNEY II XR active knee system recreates the knee’s original shape and range of motion, preventing surrounding muscles and other tissue from straining to compensate for unfamiliar stress. A U-shaped tibial base plate (top of the shin bone in the lower leg) fits around the healthy ACL and PCL, allowing them to function as they normally would rather than being removed.

Knee surgery patients with the JOURNEY II XR total knee system will likely feel less of a difference from a normal healthy knee, and greater stability. The end result may be a quicker recovery, better function, and greater satisfaction. While some may benefit, not all patients qualify for the JOURNEY II XR Knee implant. For instance, many people have ruptured their anterior cruciate ligament in their lifetime, or have developed significant angular contraction of ligaments around the knee and the JOURNEY II XR would not be appropriate in these patients. Please consult with orthopedic expert Dr. Stickney to evaluate your condition and implant options.
