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 customized fit specific to your knee

  • Femoral and tibial implants designed to follow the contour of each patient’s anatomy
  • Tibial tray designed for maximized 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 customized 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-sterilized kit in advance of surgery, which means limited implant inventory for the hospital
  • Pre-sterilized, disposable instruments and a single reusable instrument tray mean easy set up and tear down


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.
