CORI Surgical System (RI.KNEE ROBOTICS Software)
Overview
The CORI Surgical System is an advanced handheld robotic platform developed by Smith & Nephew, designed to enhance precision and efficiency in orthopedic surgery. This innovative system integrates AI-driven software, specifically RI.KNEE ROBOTICS and RI.HIP NAVIGATION, to provide surgeons with sophisticated tools for personalized surgical planning and real-time intra-operative guidance during knee and hip arthroplasty procedures.
At its core, CORI leverages artificial intelligence for several critical functions. It enables personalized planning, allowing surgeons to tailor surgical approaches to individual patient anatomy and needs. The system features image-agnostic smart mapping, which means it can generate detailed 3D models of the joint without requiring pre-operative CT scans, streamlining the workflow and potentially reducing patient radiation exposure. During surgery, it provides real-time feedback and guidance, helping surgeons execute plans with high accuracy.
For physicians, the CORI Surgical System offers the potential for improved surgical outcomes through enhanced precision and reduced variability. Its handheld design provides tactile feedback and control, allowing surgeons to maintain their preferred surgical technique while benefiting from robotic assistance. This combination of surgeon skill and AI-powered guidance aims to optimize implant positioning and soft tissue balance, critical factors in long-term patient satisfaction and joint function.
The system is cleared by the FDA, signifying its safety and efficacy for clinical use in the United States. It represents a significant advancement in robotic-assisted orthopedic surgery, providing a versatile and intelligent tool for modern orthopedic practices seeking to offer state-of-the-art care in joint replacement.

What Physicians Need to Know
Leverage the CORI System's real-time 3D modeling and AI-powered guidance for highly personalized surgical plans, eliminating the need for pre-operative CT scans and reducing patient radiation exposure. Utilize the handheld robotic precision with haptic feedback for accurate bone resections and implant placement, allowing for immediate intraoperative adjustments to optimize alignment and soft tissue balance. The system's compact design and efficient workflow can streamline OR procedures, making it a versatile tool for various knee arthroplasty indications, including revision surgeries. Consider using the CORI Virtual Planner for familiarization and practice with surgical planning.
The CORI Surgical System is a self-contained platform for knee and hip arthroplasty, integrating its handheld robotics with Real Intelligence software for planning and guidance. It is compatible with Smith+Nephew's total, partial, and revision knee systems, including cemented and cementless primary knee implant technology, and also supports total hip arthroplasty. The system's RI.KNEE ROBOTICS software is complemented by RI.HIP NAVIGATION for hip procedures. While it emphasizes image-free intraoperative mapping, Smith+Nephew also offers CORIOGRAPH Pre-Operative Planning and Modeling Services, which can include image-based registration, providing flexibility in imaging modalities. The system also integrates with the CORI Digital Tensioner for pre-cut tensioning.

What the Web Says
The CORI Surgical System with RI.KNEE ROBOTICS Software is a handheld, robotic-assisted platform for knee and hip arthroplasty, designed to enhance precision and efficiency in surgical procedures. It allows surgeons to create personalized 3D digital models of the patient's joint intraoperatively, eliminating the need for preoperative CT scans or MRIs. The system is praised by physicians for its accuracy in implant positioning, real-time planning capabilities, and its versatility in handling total, partial, and revision knee surgeries.
Overall: PositiveStrengths
- Image-free system, eliminating the need for preoperative CT scans or MRIs, which reduces radiation exposure and associated costs.
- Capable of performing both total and partial knee replacements, and is the only robotic knee system approved by the FDA for revision knee surgery in the US.
- Offers real-time planning and dynamic assessment of knee kinematics during surgery, allowing for personalized and precise implant placement and soft tissue balancing.
- Handheld design provides surgeons with direct control and haptic feedback, enhancing procedural safety and maintaining surgeon control.
- Demonstrated to reduce osteotomy time, total operative time, and intraoperative blood loss, leading to less early postoperative pain, better knee function, and higher range of motion at 3 days postoperatively compared to navigation systems.
- Portable with a small operating room footprint, making it ideal for outpatient surgery centers.
Limitations
- The handheld nature may introduce a greater degree of operator-dependent variability compared to systems with rigid robotic arms.
- Some Reddit users suggest that while robotic assistance provides more accurate implant placement, the long-term functional outcomes for patients may not be significantly different from traditional surgery, and the body is adaptable to minor misalignments.
- One Reddit user mentioned that the CORI robot is more of a navigated bur than a traditional robot.
- The system has a premium enterprise segment price point of approximately $750,000, which may be a significant investment for some facilities.
- One physician initially found robotic-assisted surgery to have increased surgical time and slow workflow, though noted the latest CORI robot is a significant step forward in data acquisition speed.
- Some studies suggest that while robotic systems improve radiological alignment, there is no clear improvement in function or outcome measurements.
