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 robotics-assisted procedure more efficiently and accurately than traditional knee replacement4,5,6

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 it’s natural rhythm and step.7

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.

Dr. Olson was born in New Haven, CT, but grew up in Wilmington, Delaware. After graduating from The Tatnall School, he attended Princeton University on a four-year Army ROTC scholarship. There he studied biology, graduating Magna Cum Laude and earning the Superior Cadet award in his class. He attended Columbia University College of Physicians and Surgeons, gaining his medical degree in 1984.

After completing his training, Dr. Olson served in the US Army for four years as chief of Sports Medicine at Walter Reed Army Medical Center, in Washington, D.C. He was deployed to Haiti for six months during 1994-1995 with the 28th Combat Support Hospital.

Dr. Olson is a member of the Waterbury Hospital Orthopedic Surgery Team.

Dr. Olson’s interests include shoulder, knee and hip arthroscopy and replacement surgery. He uses handheld robotics-assisted technology that helps him plan and perform knee procedures because the robotics-assisted approach is efficient and more accurate than traditional knee surgery.

He has also introduced other new surgical techniques to the Waterbury region including arthroscopic rotator cuff repair in 1999 and reverse total shoulder replacements in 2009. Dr. Olson is active in the Arthroscopy Association of North America and the New England Shoulder and Elbow Society. He was named a “Top Doc” by Connecticut Magazine in 2003, 2007 and 2009-2017.

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 NAVIO 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 NAVIO 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 will 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.

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.

Yes – you can.

It’s time to stop settling and start getting on with your life. You can take the stairs.*8 You can go for walks. You can stop being afraid. You can – with the ultimate knee replacement experience.
