Not everybody needs their entire knee replaced
If you only have arthritic damage to one compartment of the knee, either the medial or lateral, a total knee replacement might not be your best option.
The iUni ® unicompartmental knee implant preserves the parts of the knee parts not damaged by arthritis. As patients become more demanding and more active, the interest in bone and tissue sparing partial knee replacement approaches has increased dramatically.
Partial knee replacement surgery also retains the option for the patient to eventually move to a total knee replacement in the future should that become necessary.
The ConforMIS patient-specific approach offers many benefits with the iUni:
Provides a customized fit specific to your knee.
- Femoral and tibial implants designed to follow the contour of each patient’s unique 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
- iUni 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
- Reduced amount of bone preparation to simplify the procedure
- Fewer bone cuts to preserve more of your natural knee for future treatment, if necessary
Improved operating room efficiencies
- iUni is delivered in a single, pre-sterilized kit in advance of surgery, which means limited implant inventory for the hospital
- Pre-sterilized, disposable instruments mean easy set up and tear down
iUni offers precise femoral and tibial fit for optimal coverage and the potential for a more natural feeling knee.
Surgeons: 10 Things To Know
Not all patient-specific systems are created equal
The iUni Knee Replacement System (KRS) is intended for use in one compartment of the osteoarthritic knee to replace the damaged area of the articular surface in patients with evidence of adequate healthy bone sufficient for support of the implanted components. Only a licensed physician 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 physician 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 physician’s instructions, and other factors.
Candidates for unicondylar knee replacement include those with:
- joint impairment due to osteoarthritis or traumatic arthritis of the knee,
- previous femoral condyle or tibial plateau fracture, creating loss of function,
- valgus or varus deformity of the knee,
- revision procedures provided that anatomic landmarks necessary for alignment and positioning of the implant are identifiable on patient imaging scans.
The implant is intended for cemented use only.
