CORI Surgical System

Total or Partial Knee Replacement with the CORI Surgical System

If knee pain is slowing you down and preventing you from doing the activities you love, it may be time to consider knee replacement surgery. Whether you have arthritis, degenerative joint disease, a knee injury or lost cartilage, there’s no better time than now to get the help you need.

CORI™ Technology for Joint Replacement Surgery

Joint pain can range from mildly irritating to debilitating and becomes increasingly more common with age. Many people live in pain but the good news is, joint pain can be treated or alleviated.

What Is the CORI™ Surgical System?

The CORI Surgical System is a robotics-assisted navigation technology designed to help orthopedic surgeons perform partial and total knee replacement surgery.

How Does the CORI Surgical System Work for Knee Replacement?

CORI Surgical System works in tandem with your surgeon’s guidance to achieve precise positioning of the knee implant components during surgery. Each patient has a unique anatomy. The CORI Surgical System eliminates the need to get a CT scan of your knee before surgery. During the procedure, the surgeon uses the CORI handheld robotics technology to create a customized 3D digital model of your knee. This image helps the surgeon choose the right size of the implant for you and create a detailed surgical plan. The system sends precise information about your knee to the robotics-assisted handpiece more than 300 times per second, allowing your surgeon to remove damaged surfaces, balance your joint and position the implant with accuracy.

Benefits of the CORI Surgical System

  • Flexibility for partial or total knee replacement or knee revision surgery
  • Image-free smart mapping reduces exposure to radiation
  • Real-time gap assessment helps optimize alignment and balance for a natural fit
  • Implants made of material designed to be long lasting
  • Surgeon has access to data that may help improve outcomes
  • Faster recovery time than conventional knee surgery

Injuries & Conditions that May Need Joint Replacement

If joint pain stops you from doing the things you love, you're not living life to the fullest. Depending on your condition, your surgeon may recommend a partial or a total knee replacement using the CORI Surgical System.

Some of the injuries and conditions that may need a total knee replacement include

  • Arthritis
  • Osteonecrosis
  • Bone tumors
  • Loss of joint cartilage
  • Non-inflammatory or inflammatory degenerative joint disease

Arthritis is the most common condition that causes knee pain and disability. The three types of arthritis that cause knee pain are:

  • Osteoarthritis - age-related wear and tear type of arthritis that usually affects people 50 years old and above. Osteoarthritis occurs when the cartilage that cushions the bones of the knee softens and wears away, causing the bones to rub against one another resulting in knee pain and stiffness.
  • Rheumatoid arthritis – is a type of arthritis that occurs when the synovial membrane surrounding the joint becomes inflamed and thickened, which eventually causes cartilage loss, pain and stiffness.
  • Post-traumatic arthritis – is a type of arthritis that occurs following a severe knee injury that causes fractures in the bones surrounding the knee or tears in the knee ligaments, causing knee pain and limiting knee function over time.

What is Knee Replacement Surgery?

Knee replacement surgery, also known as arthroplasty, is a procedure that aims to decrease or eliminate knee pain by removing damaged or diseased parts of your knee bones and replacing them with an artificial joint or implants. This procedure is conducted by an orthopedic surgeon.

Types of knee replacement available with the CORI Surgical System:

  1. Total knee replacement is the most common type of knee replacement surgery wherein the surgeon removes the surface of damaged bones (i.e., thigh bone and shin bone) and replaces them with an artificial implant. Total knee replacement is an option when knee pain and damage is at an advanced stage.
  2. Partial knee replacement is also known as uni-compartmental knee replacement. It’s when the surgeon only replaces a part of the knee to keep as much of the original healthy bones and tissues as possible. Typically, partial knee replacement is an option for early to mid-stage knee pain and damage.
  3. Revision or complex knee replacement is when the patient is having a second or third joint replacement surgery on the same knee or if the patient’s arthritis worsens and caused major bone loss.

What Happens During a Knee Replacement Surgery?

Before the procedure, you may be given general anesthesia, spinal (epidural) anesthesia or peripheral nerve blocks and antibiotics to prevent any form of infection.

The orthopedic surgeon will remove the damaged or diseased bone and cartilage from where your thigh bone (femur) and shin bone (tibia) meet at your knee joint. The bone or cartilage removed will then be replaced with the implants in order to help with mobility and live a life with less pain.

Do You Need Knee Replacement Surgery?

Doctors may recommend knee replacement surgery to adults of any age, although it is more common in older adults. You may be referred for knee replacement surgery for patients after you have tried to get rid of pain with medication, cortisone injections, unsuccessful physical therapy or if you are suffering from any of the following:

  • Osteoarthritis (OA) is a breakdown of joint cartilage that limits movement and may cause pain
  • Other forms of arthritis, such as rheumatoid arthritis (RA) and arthritis that results from a knee injury
  • Damage to the knee, such as fractures, torn cartilage and/or torn ligaments
  • Orther degenerative joint diseases (i.e., hip dysplasia and avascular necrosis (AVN)

What to Expect From Knee Surgery

If you and your doctor decide knee replacement surgery is the best treatment, your doctor will let you know exactly what to expect before, during and after surgery. Your team will follow up with you to help ensure that your new knee is doing well.
