CORI Robotic-Assisted Knee Surgery

Is living with knee pain really living? If you’re one of the estimated 30 million Americans suffering from osteoarthritis, discover how knee replacement using CORI Surgical System robotic assistance may help you return to the activities you love.

Our physicians use the CORI Surgical System to perform robotics-assisted partial knee replacement. They chose this technology because it allows them to individualize each patient’s knee replacement surgery, and use robotic assistance for accurate results.

With the CORI Surgical System, there is no special pre-operative preparation or post-operative recovery protocol. The CORI Surgical System does not perform the procedure. Rather, it assists the surgeon by providing accuracy – crucial to the success of the surgery.


  • Lower Post Operative Pain
  • Lower Risk of Complications
  • Minimally Invasive Surgical Techniques
  • Smaller Implants
  • Less Removal of Bone and Cartilage

Meet the CORI Surgical System, a robotics-assisted knee surgery platform that adds an extra layer of pre-surgical planning and improved precision for partial and total knee replacement procedures.

The CORI Surgical System is an advancement in the way our orthopedic surgeons perform total and partial knee replacements. The system works in conjunction with our surgeon’s skilled hands to achieve the precise positioning of the knee implant based on each patient’s unique anatomy. This added level of accuracy can help improve the function, feel and potential longevity of the knee implant.

Robotic Assisted Planning

Using the CORI Surgical System, your surgeon creates a 3D representation of the unique shapes and profiles of your knee without the need for a pre-operative CT scan. Using all of this information your surgeon can then determine the correct size and position of the implant. Implant size and position are critical to knee alignment and stability. Next, your surgeon uses the robotic assistance of CORI  to physically remove only the damaged bone, preparing the site for the prosthesis, before placing and adjusting your partial knee implant.

Total Knee Replacements

In a total knee replacement, the entire knee joint is replaced with a prosthetic implant designed to replicate the shape, motion, and stability of your natural knee joint. Total knee replacement is one of the most common procedures performed in all of medicine, with over 600,000 performed in the U.S. every year. Ninety percent of people who receive a total knee replacement experience a dramatic decrease in knee pain, and an improvement in their ability to perform daily activities.

Partial Knee Replacements

In a partial knee replacement, your supporting tissue and ligaments that help stabilize your knee are spared and only the damaged portion of the knee is replaced. This means that healthy cartilage and bone remain intact to help your knee joint move smoothly with the prosthetic implant. Patients with osteoarthritis in only one area of their knee may be candidates for partial knee replacement. Patients who undergo partial knee replacement often report a ‘more normal’ feeling knee, less pain and quicker rehabilitation.
