Smith+Nephew, changing the face of orthopaedics

As digital health looks to transform total joint surgery, our vision embodies the perfect balance and seamless synergy of surgeon skills and cutting-edge enabling technology. Placing surgeons at the heart of a digital OR, with software solutions, next-generation hardware and data analytics all built to evolve and grow towards the ultimate aim of new heights in patient outcomes and satisfaction.

What is Real Intelligence?

How Smith+Nephew thinks, innovates and re-imagines surgery

While others focus on Artificial Intelligence(AI) as their path to the future, we take a different approach. Real Intelligence: where the power of human insight and experience work together with technology to create new care pathways. We continue to be a leader that delivers innovative technologies that make a 'real' difference in the lives of patients and in orthopaedics.


CORI Surgical System

CORI combines surgeon skill with next-generation handheld robotics in total and unicompartmental knee arthroplasty, building on our existing technology with improved camera technology1 and more efficient cutting1 to facilitate a faster procedure. With a portable, modular design and a small OR footprint, it acts as a focal point for a surgeon-controlled digital ecosystem built to grow and evolve across the continuum of care.

Implant portfolio


Total Knee Implants

Despite being a successful treatment for pain and function, total knee surgery patients report unmet levels of satisfaction, with functional limitations and difficulties in daily activities1,2. Featuring OXINIUM Technology, our implant portfolio is designed to reproduce anatomical shape, position and kinematic patterns3-5, helping to deliver superior clinical outcomes and patient satisfaction2,5-9.

Bi-cruciate retaining system designed to replicate kinematics, proprioception10 and stability, with OXINIUM Technology and less invasive ligament retention

Posterior cruciate retaining system with a convex lateral surface for native rollback and a prominent posterior medial lip for mid-flexion stability, paired with OXINIUM Technology

Bi-cruciate stabilised system featuring OXINIUM Technology, designed to restore anatomic alignment and normal knee kinematic patterns

Partial Knee Implants

For a highly personalised approach with customisable instrumentation, our partial knee implant portfolio focuses on asymmetric, anatomic design to replicate knee alignment and kinematics. Available in a range of versions and sizes for versatility across various patient requirements, and paired with advanced OXINIUM Technology.

Uses proprietary OXINIUM Technology and facilitates a highly personalised approach via a modular, two-tray configuration; featuring a lateral-specific tibia baseplate and customisable instrumentation


OXINIUM Oxidized Zirconium

Through a Moment of Change in manufacturing, our implants undergo a material transformation resulting in a ceramicised metal surface providing the durability of metal, the wear properties of a ceramic and corrosion resistance better than both.1-7 Containing virtually zero nickel cobalt and chromium, OXINIUM Oxidized Zirconium is an implant material that provides lower pro-inflammatory response in vitro compared to traditional cobalt chrome.8-10
