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.
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.

A unique plan
Your knee replacement surgery is as unique as you are because it’s the only one that combines your knee’s anatomy with the specific implant your surgeon chooses for you. As a result, your surgery requires an individualized surgical plan to help ensure your implant is positioned and aligned correctly for your anatomy. With robotics-assisted surgery, your surgeon uses the CORI◊ Surgical System to create a customized 3D digital model of your knee. This three-dimensional view helps your surgeon finalize and verify the right size implant for you and create a detailed surgical plan for how your replacement will be placed in order to optimize movement and function. As an added benefit, 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.
For reasons no one fully understands, in rheumatoid arthritis, the immune system – which is designed to protect our health by attacking foreign cells such as viruses and bacteria – instead attacks the body’s own tissues, specifically the synovium, a thin membrane that lines the joints.
Knee pain doesn’t necessarily mean knee surgery. There are many options for you to discuss with your doctor to help alleviate knee pain.
Although knee replacement surgery is often referred to as a “mainstream procedure,” and is considered one of the most successful procedures in all of medicine, every surgical procedure comes with risk of complications.
