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.
Knee replacement is most commonly performed as an inpatient procedure in a hospital. However, as healthcare options expand and surgical techniques continue to improve, alternatives including outpatient surgery and shorter hospital stays are becoming more common.
Arthritis of the knee is a disease which wears away the cartilage between the femur (thigh bone) and the tibia (shin bone) causing the two bones to scrape against each other, raw bone on raw bone.
Although the degenerative process may accelerate in persons with a previous knee injury, many cases of osteoarthritis occur when the knee simply wears out.
