Using CORI◊ in total knee arthroplasty
The CORI Surgical System provides portable, handheld robotics with the smallest footprint+ in knee arthroplasty. The technology is designed to help surgeons achieve more accuracy in bone resection and alignment through intraoperative planning, smart mapping and full range-of-motion data collection, for reduced wear and higher implant survivorship.*2-10
RI.KNEE Robotics applications on CORI◊ Surgical System
RI.KNEE Robotics software delivers a surgical workflow designed to improve efficiency and usability, and further decrease the learning curve.***
Image-free, smart mapping:
Real-time characterization of bone and cartilage through landmark collection and point mapping without preoperative imaging. Enhanced robotic software solution that delivers:
- Image-free, smart mapping (No CT/MRI required)
- Real-time planning and gap assessment
- Optimized* alignment and balance
- Automated knee model rotation eliminates the need for additional screen manipulations
- Software indicates critical regions for collections and notifies if collection is not complete
Enhanced workflow provides:
Fewer registration steps
- 72% reduction in required data point collection, with automatic landmark capture***
- 40% reduction in workflow stages, with improved usability***22 and faster, image-free smart mapping
- 2.5x larger data point collection area, with faster surface model generatione***22
- Single stage, patient-specific planning
Customizable, surgeon-controlled planning:

- Size, orient and align components virtually on a 3D model
- Confirm implant placement relative to the articulating surface
- Adjust implant placement to balance soft-tissue throughout the full range-of-motion (UKR only)
Robotics-assisted bone preparation:

Handheld milling technique utilizes the latest innovation in milling technology, allowing surgeons to cut more in less timey,*1 while leaving a smooth finish.
- Redesigned robotic handpiece provides improved ergonomics*1
- New bur designs delivering 2X cutting volume*1
- 29% faster resection*1
