The ultimate knee replacement experience

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

Designed for you

With 3D digital modeling from the CORI^◊ Surgical System 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.

Robotics-assisted Surgery

The latest innovation from Smith+Nephew is our handheld robotics-assisted technology for partial and total knee replacements. This advanced technology enables your surgeon to plan and perform your surgery with a greater degree of accuracy than is possible with traditional methods.⁹

A unique plan

Your knee replacement surgery is as unique as you are. After all, it is the only one that’s based on the combination of your individual knee anatomy and the specific implant your surgeon has determined is right for you. To help ensure your implant is positioned and aligned correctly to your anatomy, the CORI^◊ Surgical System creates a customized 3D digital model of your knee. This three-dimensional view helps your surgeon choose the right implant for you. In addition, the 3D digital model eliminates the need to get a CT scan of your knee before your surgery, which reduces your exposure to harmful radiation.

A natural fit

The benefits of robotics-assisted surgery is about more than just a detailed 3D view of your knee. The CORI^◊ Surgical System also helps ensure your procedure is performed as the surgeon planned it, giving you the benefits of enhanced accuracy when compared to traditional knee surgery. Accuracy is important because it not only helps the implant function as intended, it also helps avoid uneven wear which can shorten the longevity of an implant.

More implant options

Unlike other robotics platforms, our system works with all of our partial and total knee implants – including those made from our exclusive VERILAST Technology for added durability. This wide selection allows your surgeon to chose the right implant for you.

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.

What is OXINIUM^◊ Oxidized Zirconium?

If it is determined that an implant made with VERILAST◊ technology is right for you, the femoral – or thighbone portion – of your implant will be made from – a patented and award winning ceramicised metal alloy that Smith+Nephew spent more than a decade developing.

During manufacture, OXINIUM implants undergo a process that transforms the implant’s surface into a hard, ceramicised metal – while still retaining all of the durability of the underlying metal. In addition to being more durable than a true ceramic, this metal implant’s ceramicised surface is more than twice as hard and therefore twice as resistant to the kind of scratching that can cause a cobalt chrome implant to wear out before its time.¹⁰

A wide selection

Every patient is unique. So why do other robotic systems restrict surgeons to only one or two implant options? Our CORI Surgical System lets your surgeon choose from a wide selection of implants available. This means that whether you’re getting a partial or a total knee replacement, you know your implant will be precision-matched to your needs.
