An alternative to total knee replacements

Today, many patients with osteoarthritis of the medial or lateral compartment plus patellofemoral receive a total knee replacement (TKR) without consideration of other options.

The iDuo® offers an alternative to traditional TKR by combining proven principles for patellofemoral treatment with the advantages of the ConforMIS partial knee system:

Provides a patient-specific fit specific to your knee

    • Femoral and tibial implants designed to follow the contour of each patient’s anatomy
    • Tibial tray designed for maximised cortical rim coverage and proper rotational alignment


Designed to mimic the natural shape of your knee

  • The shape of your knee plays an important role in how you bend and extend your knee
  • iDuo® is designed to mimic the natural shape of your knee, which gives your knee the potential to feel and move more naturally

Allows for a less traumatic procedure

  • iJig® instrumentation customised for each patient using CT scan data
  • Preserves all ligaments and conserves far more bone than traditional TKR
  • Fewer bone cuts to preserve more of your natural knee for future treatment, if necessary

Improved operating room efficiencies

  • iDuo® is delivered in a single, pre-sterilised kit in advance of surgery, which means limited implant inventory for the hospital
  • Pre-sterilised, disposable instruments and a single reusable instrument tray mean easy set-up and disposal

iDuo® allows the surgeon to treat just the affected compartments of the knee in a procedure that not only provides patients with the potential for more natural knee motion, but also preserves future treatment options—a benefit to both patients and surgeons alike.

The iDuo Knee Repair System (KRS) is intended for use in patients with severe knee joint pain and disability whose conditions cannot be solely addressed by the use of a prosthetic device that treats only a single knee compartment. Only a licensed doctor can help you determine the appropriate medical treatment. There are potential risks to knee replacement surgery, and individual results may vary. Before making any decisions concerning medical treatment, consult your doctor regarding your options and the risks of those options. The longevity, performance and feel of any knee implant will depend on various factors, including your physical condition, your activity level, adherence to your doctor’s instructions, and other factors.

The indications for use including restoring joint function and relief of pain due to:

  • painful joint disease due to osteoarthritis
  • traumatic arthritis of the knee
  • post-traumatic loss of joint function
  • failed osteotomies, hemiarthroplasties, and unicondylar implants
  • revision procedures provided that anatomic landmarks necessary for alignment and positioning of the implant are identifiable on patient imaging scans

The iDuo KRS may be used when the medial or lateral condyle and the patellofemoral areas have been affected by one or more of these conditions.

This implant is intended for cemented use only.

Caution: US federal law restricts this device to sale by or on the order of a doctor.
