Recent advances in biomedical engineering software have opened a new chapter in
high performance knee implants.

One remarkable breakthrough has been the creation of the JOURNEY knee, a first-of-its-kind knee replacement that combines the stability and natural motion of the human knee with new low-friction materials that may extend the life of the implant.

While the lifespan of a knee implant is heavily influenced by the materials used to make it, the natural feeling of
the implant during physical activity is dependent upon
the way the patient's muscles, ligaments and tendons
are addressed during surgery and by the implant's
shape within the body after surgery.

The knee is a hinge joint, but it does not swing like a simple door hinge. It has a complex rotational motion that you don't notice is there—but many patients know when it's not there after total knee replacement. Traditional implants do not accurately recreate this subtle swing- and-rotate action.

As a result of these traditional designs, the muscles
and ligaments around the new joint have to work harder because the implant's slightly unnatural shape and resulting motion make these soft tissues move in nfamiliar, stressful ways. This leads to joint pain,
muscle fatigue and the unnatural feeling patients experience while walking or bending in the months
after their procedure.

The JOURNEY knee, on the other hand, is the only
knee implant designed to reproduce the original internal shapes and angled forces of the human knee through
its full range of motion—accommodating the swing-and-rotate of the joint with the same engineering principles your real knee currently uses. Because of this, your soft tissues don't have to readjust to new shapes and forces after surgery and your stride can return to its
natural rhythm.

The JOURNEY knee also reproduces the stability
provided by your anterior cruciate ligament (ACL) and
your posterior cruciate ligament (PCL). Your ACL and PCL are key to the stability of your real joint and contribute to natural motion when your knee is fully extended and fully bent. No other knee implant reproduces both functions.
