The CORI Surgical System with RI.KNEE ROBOTICS software is the first robotic-assisted platform indicated for use in revision knee arthroplasty in the US, and may help to mitigate technical challenges in these procedures1
Featuring the LEGION◊ RK Revision Knee System with OXINIUM◊ Technology.
Revision knee arthroplasty poses several challenges, such as difficulty in restoring the normal joint line2 and achieving balanced flexion/extension gaps. 3 Robotic technology is increasingly used to complement conventional surgical procedures4 and may help to address these challenges.
The CORI System platform is designed to support surgeons performing revision knee procedures5 by allowing for:
Mapping of all areas of the knee without the need for CT or MRI imaging by building a 3D model of bone surfaces
Real-time, full range of motion gap assessment to inform implant placement and soft tissue balancing
Intra-operative visualization of bony defects to help with augment planning and to preserve the normal joint line
Efficient and accurate bone removal using precision milling
