CORI Surgical System

CORI Surgical System

What is the CORI Surgical System?

The CORI Surgical System is an advanced robotic platform designed for orthopedic surgeries, particularly knee replacement procedures. Developed by Smith & Nephew, this handheld robotic system leverages robotics and computer-assisted technology to enhance precision and efficiency during surgical procedures.

What are the Key Features of the CORI Surgical System?

Some of the key features of the CORI Surgical System include:

• Robotic Assistance: The system aids surgeons in planning and executing precise bone cuts and implant placements, aiming for better alignment and fit of the prosthetic components.
• Real-Time Data: The system provides real-time feedback and data to the surgeon, helping to make informed decisions during the procedure.
• Customisation: It allows for personalised surgical plans tailored to the individual patient's anatomy, potentially improving the overall outcome of the surgery.
• Enhanced Visualisation: Surgeons benefit from enhanced visualisation of the surgical field, improving accuracy and control during the procedure.
• Training and Support: Smith & Nephew provides comprehensive training and support for surgeons using the CORI Surgical System, ensuring they can effectively utilise the technology in their practice.

What are the Indications for the CORI Surgical System?

Smith & Nephew’s CORI surgical system is typically indicated for partial and total knee replacement in patients suffering from degenerative knee disease, such as osteoarthritis, that is not responsive to conservative treatment.

Osteoarthritis is a degenerative joint disease that causes breakdown and eventual loss of cartilage in the knee joint making the bones rub against each other leading to painful movement.

Total knee replacement, also called total knee arthroplasty, is a surgical procedure in which the worn-out or damaged surfaces of the knee joint are removed and replaced with an artificial knee implant or prosthesis. Partial knee replacement is a surgical procedure in which only the damaged portion of the knee joint is removed and replaced with a prosthesis.

How is Knee Replacement Using the CORI Surgical System Performed?

In general, knee replacement using the CORI Surgical System may include the following steps:

• Setup: The patient is positioned on the operating table, and the surgical area is sterilised. Anaesthesia (general or regional) is administered.
• Registration: The CORI Surgical System's handheld device is used to map the anatomy of the knee joint. This registration process involves capturing precise data points on the bone surfaces.
• Robotic Assistance: Based on the preoperative plan and real-time data, the CORI system assists the surgeon in making precise bone cuts. The handheld device provides tactile feedback and guidance to ensure accuracy.
• Bone Preparation: The damaged portions of the femur (thighbone) and tibia (shinbone) are removed using the robotic system. The surface is then prepared to fit the prosthetic components.
• Implant Positioning: The prosthetic components are placed and secured in the prepared bone surfaces. The CORI system ensures that the implants are positioned accurately according to the preoperative plan.
• Balancing the Knee: The surgeon checks the alignment and balance of the knee joint to ensure proper function and stability. Any necessary adjustments are made.
• Closure: The surgical incision is closed using sutures or staples, and a sterile dressing is applied.

What is the Postoperative Care Involved in CORI Surgical System Assisted Knee Replacement?

Following surgery, you will require pain management with medications and ice packs. Incision site care and bathing instructions will be provided to keep the wound clean and dry. You should refrain from strenuous and heavy lifting activities for a defined period. A knee brace or immobiliser may be recommended to protect the repair, depending on your surgeon’s preference. 

The healing process may take anywhere from 8 to 12 weeks. You will require the use of crutches until you are able to walk without assistance. A physical therapist will teach you specific exercises to strengthen your leg muscles and restore knee movement. You should be able to resume your normal activities in a couple of months. Follow-up appointments will be scheduled to monitor your progress.

What are the Risks and Complications of CORI Surgical System Assisted Knee Replacement?

Knee replacement using the CORI Surgical System is a relatively safe procedure; however, as with any surgery, some risks and complications can occur, such as:

• Pain
• Bleeding
• Infection
• Knee stiffness/instability
• Blood clots or deep vein thrombosis (DVT)
• Allergic/anaesthetic reactions
• Injury to nerves or blood vessels

What are the Benefits of the CORI Surgical System Assisted Knee Replacement?

Benefits of knee replacement using the CORI Surgical System include:

• Smaller incisions
• Minimal postoperative pain
• Minimal muscle trauma/scarring
• Greater accuracy in implant placement
• Improved implant longevity
• Shorter hospital stay
• Rapid recovery
• Lower risk of revision replacement
• Higher patient satisfaction
