Computer assisted knee replacement surgery

Computer Assisted Knee Replacement Surgery


Anatomy of knee

Anatomy of Knee

  • The knee is made up of three bones

    • Femur (thigh bone)

    • Tibia (lower leg bone)

    • Patella (knee cap)


Causes of knee arthritis

Causes of Knee Arthritis

  • Wear and tear

  • Fractures, torn cartilage and torn ligaments


Symptoms of arthritis

Symptoms of Arthritis

  • Pain

    • During activity

    • At rest or sleeping

  • Swelling and tightness

  • Bone spurs

  • Grinding sound during movement

  • Stiffness and decreased range of motion


What potential benefits can knee replacement provide

What potential benefits can knee replacement provide?

  • A return to mobility

  • Reduce or eliminate pain


When may knee replacement surgery be right for you

When may knee replacementsurgery be right for you?

  • Experience significant pain

  • Knee function and mobility decreases

  • Physician recommends joint replacement


Traditional knee replacement surgery non computer assisted

Traditional Knee Replacement SurgeryNon-computer-assisted

  • Surgical treatment through knee replacement of advanced knee osteoarthritis and other diseases

  • About 300,000 people undergo knee replacement in the U.S. annually1

Surgical procedure

Surgical Procedure

  • Arthritic surfaces at the end of the tibia and femur are removed

  • Bones are prepared for new covering

  • Femoral and tibial components are attached

  • Patella is resurfaced


What is computer assisted surgery

What is computer-assisted surgery?

  • A new approach to knee replacement

  • The patient’s anatomy is simulated and displayed on a computer

  • Computer provides infor-mation about where to place the components


How does the ci system work

How does the Ci™ System work?

Computer calculates the best position to place the components for accurate alignment

Camera searches for arrays placed on the patient via infrared signals.

Patient’s anatomical information is entered into the computer through a process called registration.

Information is fed back to the camera and communicated to the computer


Potential benefits

Potential Benefits

  • Guides surgeon in areas that are difficult to visualize.

  • Relays specific measurements not previously available to surgeons.

  • Gives precise, accurate data on the patient’s own anatomy.

  • Allows surgeons to make informed decisions about precise implant placement based on detailed data from the computer.


Why use computer assisted knee replacement surgery

Why use computer-assisted knee replacement surgery?

  • Advanced knee replacement technology combined with widely used, clinically successful implants.

  • Allows surgeons to be more precise when making decisions about placing knee components.

  • Provides the surgeon with extensive information to assist with surgical decisions.


What potential complications can knee replacement have

What potential complications can knee replacement have?

  • Loosening, deformation or wear of one or more of the components, osteolysis, infection, DVT and fracture of the components or bone.

  • Note: This procedure is not for everyone. As with any surgery, there are risks. Recovery takes time and hard work. The life of a joint replacement depends on weight, activity level, age and other factors. Each patient responds differently.
