iUni and iDuo

iUni and iDuo are fully personalized or patient-specific partial knee replacement options for either unicompartmental or bicompartmental osteoarthritis of the knee. Both products offer customized femoral and tibial implant fit and shape, which gives the knee the potential to feel and move more naturally, and simple surgical technique.

Benefits of iDUO

• Offers unlimited femoral and tibial component shapes and sizes, anatomic shapes with ligament preservation for natural kinematics, full coverage of all weight-bearing areas, and tibial components precisely matched to the cortical rim.

• Resurfaces the femur with minimal bone resection, uses a tibial component that treats only the affected compartment, preserves the ACL and PCL, requires no intramedullary canal preparation, and retains significantly more healthy tissue to preserve future surgical options.

• Features iJig® patient-specific instrumentation, enabling fewer bone cuts and steps, minimal intra-operative sizing or trials, and iView patient-specific planning images.

Benefits of iUNI

• Features an anatomic shape and fit for natural kinematics, full coverage of all weight-bearing areas, a tibial component matched to the cortical rim, and articulating surfaces engineered to reduce contact stress.

• Offers a resurfacing solution with minimal bone resection, preserves the ACL and PCL, avoids intramedullary canal penetration, and allows for revision to a primary total knee arthroplasty (TKA) if needed.

• The system includes iJig® patient-specific instrumentation, enabling fewer bone cuts and steps, minimal intra-operative sizing or trials, and iView® patient-specific planning images for enhanced precision.
