Total Knee Replacement With CORI Surgical System


  • The traditional knee replacement procedure is carried out using saws and jigs, which has the potential to introduce errors.
  • These surgical errors may result in pain, instability and early revision. Hence, arises the need of minimally invasive techniques & tools.

The CORI Surgical System

  • The CORI system is a compact and fully mobile solution incorporating a 3-D intra-operative imaging system with an advanced robotic sculpting tool.
  • CT free, reducing both financial cost and radiation exposure to patients
  • Robotics system allows surgeons to measure, plan, and perform a knee surgery which is personalised to the patient’s individual anatomy.
  • The Smith + Nephew system is considerably more compact than alternative robotic systems, has minimal set up time, and is portable providing potentially an immediately scalable solution.
  • The benefits of robotics-assisted surgery for patients are myriad
    • Improved accuracy
    • Significantly improved patient reported outcome measures (PROMs)
    • Shortened length of hospital stays.
    • Evidence of an earlier return to an active lifestyle.
  • This robotic system provides greater accuracy and precision with the aim of improving patient outcomes and allowing them to return to normal life.

Osteoarthritis & the Knee

  • The knee is a hinge-like joint made up of the Femur (thighbone), Tibia (shinbone), and Patella (kneecap).
  • The hinge-like knee joint is held together by muscles, ligaments and other important soft tissue.
  • In between the knee is a natural cushioning called meniscus that is made up of cartilage.
  • This material provides shock absorption during weight bearing activities such as walking or climbing stairs.

Over the years due to the wear and tear, the cartilage in your knee can break down causing a disease known as OSTEOARTHRITIS.

  • Osteoarthritis, a degenerative joint disease that affects mostly middle-aged and older adults, may cause the breakdown of joint cartilage and adjacent bone in the knees.
  • The factors that can lead to the progression of Osteoarthritis include Age, obesity, heredity, gender and other factors.
  • Common symptoms include pain, swelling and stiffness.

Total Knee Replacement (TKR)

What is Total Knee Replacement?

  • Knee replacement, also called knee arthroplasty or total knee replacement, is a surgical procedure to resurface a knee damaged by arthritis.
  • Metal and plastic parts are used to cap the ends of the bones that form the knee joint, along with the kneecap.
  • This surgery may be considered for someone who has severe arthritis.

The goal of knee replacement surgery is to resurface the parts of the knee joint that have been damaged and to relieve knee pain that cannot be controlled by other treatments.

Why & When to consider Total Knee Replacement?

People who require knee replacement surgery commonly have problems in walking, climbing stairs, and getting in and out of chairs. Some also have knee pain at rest.

Knee replacement surgery should be considered when all conservative measures fail to provide relief.

Surgery may be performed for the following reasons :

  • Relieve pain
  • Improve joint stability
  • Improve alignment and correct bone deformity
  • Maximise quality of life
  • Optimise activities of daily living

Non surgical treatment options before considering TKR

  • Lifestyle changes : lose weight and avoid aggravating activities to reduce the stress on your knee.
  • Exercises : surgeon prescribed low impact exercises designed to improve strength and flexibility.
  • Anti-inflammatory medications : intended to decrease swelling in the joint and provide temporary pain relief.
  • Cortisone/steroid injection : powerful anti-inflammatory agent injected directly into the joint.
  • Joint fluid therapy : Hyaluronic Acid Injections to improve Joint Lubrication.
  • Glucosamine/chondroitin : dietary supplements intended to support joint health.
  • Bracing : used to provide external stability to the knee.

  • CORI Surgical System is a surgical planning and computer-assisted surgery system that facilitates improved surgeon-defined results.
  • CORI employs advanced instrumentation and software to automate the complex tasks of knee joint positioning, sizing and alignment necessary prior to total knee replacement surgery.
  • Its advanced instrumentation is built to ensure the procedure is carried out just as your surgeon intended, resulting in reduced surgical risk and faster recovery times for patients.

What to expect in Surgery?

  • Under Anaesthesia, an incision will be made extending from the area above the knee cap to below the Knee Cap.
  • Using the robotic system, special trackers are secured to both the thigh bone (femur) and shin bone (tibia) with four small surgical pins placed through tiny incisions in the skin.
  • Using computer assistance, the unique shape and motion of your knee are collected by the surgeon. This allows for a three-dimensional model of your knee to be generated and used by the surgeon to plan the procedure.
  • Once your surgeon virtually determines the correct implant size and positioning, a handheld robotics assisted tool is used to accurately remove the damaged cartilage & replace it with prosthetic implant.
  • Once the implant is in the final position, the incision is thoroughly cleaned and closed, completing the procedure.
