The ultimate knee
replacement experience

See how knee replacement has changed – and what it can do for you.

A unique plan.

With 3D digital modeling, you get a surgical plan that’s customized to your unique anatomy. That means your surgeon can perform your procedure more efficiently and accurately than traditional knee replacement surgery.1

A natural fit.

With a robotics-assisted procedure using Smith+Nephew implants, you can keep more of your natural bone and ligaments, including the ACL. That means your body can maintain more of its natural rhythm and step.2

A wide selection.

With Smith+Nephew knee implants, your surgeon is choosing from the widest selection available. That means your implant can be precision-matched to feel more like your own knee.

Higher patient satisfaction—Smoother recovery4,5,6

The JOURNEY◊ II Knee System has been demonstrated to improve a patient's range of motion more quickly after surgery. This faster recovery, along with the implant's normal pattern of motion, have been shown to lead to high levels of patient satisfaction.

An implant built to last

With Smith+Nephew knee implants, your surgeon has access to OXINIUM◊ Oxidized Zirconium. This unique metal alloy is designed to reduce the effects of implant wear and tear. In fact, OXINIUM knee implants have been lab-tested for durability 9-times longer than the international standard for joint replacements7.

Sleep in your own bed

Did you know that knee replacement surgery can be an outpatient procedure? You can have surgery in the morning and be sleeping in your own bed that same night—with the same Smith+Nephew implants and technologies available in the traditional hospital setting.

VERILAST◊ Technology

Unlike other implants that are only available with cobalt chrome for their metal femoral components, the JOURNEY◊ II Active Knee implant can also be made with a proprietary metal alloy called OXINIUM◊ Oxidized Zirconium. While cobalt chrome has been used successfully for years, laboratory tests have shown that the "ceramicized" OXINIUM metal alloy is twice as hard as cobalt chrome and can be twice as resistant to the type of scratching that can cause implant wear. First introduced in 1997, OXINIUM implants have been used in more than 1 million surgeries around the world.

And since each implant is a combination of metal and plastic, JOURNEY II implants also use a harder, highly cross-linked polyethylene known as XLPE for the plastic insert.

Working together, these materials form a bearing surface combination known as VERILAST Technology, which is unique to global medical device maker, Smith+Nephew.

What Is JOURNEY◊ II Technology?

The JOURNEY II AKS Difference

One of the most remarkable breakthroughs in design of total knee replacements has been the creation of the JOURNEY II Active Knee Solutions. Designed using the latest in human simulation software, and built using some of the most wear-resistant materials available, this unique implant was designed to address two of the most common concerns associated with knee replacement implants: implant wear and implant feel.

Commonly described as a hinge joint, your knees actually do much more than simply swing back and forth. In fact, every time your knee bends, forces in and around the joint work together to produce a subtle and complex rotational movement that you don't even realize is there. However, if this rotational movement is removed, the change can be felt in the muscles and ligaments through the entire leg.
