Smith+Nephew Debuts Revision Knee Indication on Robotics Platform

It can address robotic-assisted total, partial, and now revision knee arthroplasty.

Smith+Nephew announced the first cases for revision knee replacement utilizing its CORIâ—Š Surgical System.

Dr. Thorsten Seyler of Duke University performed the first cases on August 17, 2022, combining Smith+Nephew's handheld robotics technology with its LEGIONâ—Š Revision Knee System. Smith+Nephew is the first orthopaedics company to receive FDA 510(k) clearance for a revision indication using a robotics-assisted platform.

RI.KNEE ROBOTICS uses image-free smart mapping, eliminating the need for pre-operative CT/MRI scans and the potential for image distortion due to in situ components from the primary procedure. Instead, surgeons are able to build patient-specific 3D models of the joint, register anatomy and bony defects after implant extraction, intra-operatively gap balance in real-time, and accurately precision mill for final placement of components.1-4

"The ability to visualize and create symmetric and balanced flexion and extension gaps with the CORI handheld robotic system has made one of the most challenging tasks in revision TKA an easier undertaking. I have never used more posterior stabilized over constrained bearings in a revision scenario. Additionally, the image-free system also allows for accurate mapping of bone defects after implant removal and enables surgeons to use a bone preserving approach to revision TKA," said Dr. Seyler.

With broader capabilities and expanded indications, it can address robotic-assisted total, partial, and now revision knee arthroplasty, along with computer-guided total hip arthroplasty. By coupling robotics with Smith+Nephew's clinically-proven LEGION RK System with OXINIUMâ—Š Technology5, surgeons can experience a truly comprehensive implant and technology portfolio.

"Being first to market with a revision indication for robotic-assisted knee replacement surgery is a significant milestone in orthopaedics," said Randy Kilburn, Executive Vice President & General Manager, Orthopaedic Reconstruction, Robotics and Digital for Smith+Nephew. "Our ability to offer a robotic-assisted solution for partial, total, and now revision knee arthroplasty using a single platform is a true differentiator, especially when it potentially simplifies a complex procedure and maximizes the system's capabilities for surgeons to restore patient lives and live Life Unlimited."

Over the last six months, Smith+Nephew has launched RI.HIP NAVIGATION, RI.HIP MODELER, "Cementless" CONCELOCâ—Š Advanced Porous Titanium 3D printing technology with LEGIONâ—Š CONCELOC Cementless Total Knee System, and now a revision knee indication. All are supported by the CORIâ—Š Surgical System.
