Overview

The CORI Surgical System is a robotics-assisted technology for knee replacement. It creates detailed images of your unique knee anatomy, which can help your surgeon customize your replacement procedure. Studies show that a robotics-assisted approach to knee replacement may offer better accuracy than a traditional (non-robotics) surgery.1

What is robotics-assisted surgery with the CORI Surgical System?

A key element to the success of your knee replacement is the correct positioning of your new implant. With traditional knee replacement surgery, the surgeon uses manual methods to determine the position and alignment of the implant. This may include inserting a metal rod into the bone to assess alignment.

Robotics-assisted surgery offers a different option. With the CORI Surgical System, your surgeon creates a digital 3D model of your knee to help determine correct placement of the implant. Important calculations for alignment and movement can be done before any bone is altered. Studies show that a robotics-assisted approach to knee replacement may offer better accuracy than a traditional (non-robotics) surgery.1

The benefit for you is a customized knee replacement surgery.1

Is robotics-assisted knee replacement right for me?

To find out if robotics-assisted knee replacement is a treatment option, make an appointment with an orthopaedic surgeon. The surgeon will examine your knee and review your health situation in determining if knee replacement is recommended. Here are other things to know:

What are the risks involved?

All surgery has risks and the potential for complications. Talk to your surgeon about any concerns you may have before you decide on treatment. Some of the possible risks and complications for knee replacement include:

  • Blood clotting
    Blood clotting problems – such as deep vein thrombosis (DVT) or pulmonary embolism (PE) – may occur after surgery and interrupt normal blood flow. Your medical team may recommend medications and exercises to reduce the risk.


  • Infection
    Infection may occur at the surgical site or elsewhere in the body. If a serious infection occurs, additional surgery or removal of the implant may be needed.


  • Pneumonia
    After surgery, pneumonia or other breathing problems may develop. Your medical team may recommend measures to reduce the risk.


  • Nerve problems
    Nerves or blood vessels in the knee area may be damaged during surgery.


  • Long-term pain and stiffness in the knee
    Most patients experience pain relief after knee replacement, but some continue to have pain.3 Similarly, some develop joint stiffness. Following the recovery guidelines provided by your medical team may help reduce this risk.


  • Implant wear or failure
    The knee implant may become worn, loose, or damaged. It may not perform as expected. In some cases, another surgery may be needed to correct or replace the implant.


This is not a complete list of complications. Talk to your surgeon about the possible risks for your specific health situation.

All information provided on this website is for informational purposes only and is not meant as medical advice. Not everyone is a candidate for hip replacement with the CORI Surgical System, and individual results of joint replacement will vary. Implants are intended to relieve hip pain and improve function but may not produce the same feel or function as your original hip. Every patient's case is unique, and each patient should follow his or her doctor's specific instructions. Potential risks include loosening, wear, and infection that may result in the need for additional surgery. Discuss your implant options with your surgeon. Please discuss nutrition, medication, and treatment options with your doctor to make sure you are getting the proper care for your particular situation. If you are seeking this information in an emergency, please call 911 and seek emergency help.
