Ask your surgeon about ConforMIS – the ONLY customized total knee implant made to fit your knee, and only your knee.

ConforMIS customized knee systems use advanced computer technology to create an implant made just for you. These patient-specific are designed to fit your knee precisely and preserve more of your bone,* providing you with the potential for a more  natural feeling knee.

One Patient. One Implant.

ConforMIS does something that we believe no other knee replacement company does – we design and manufacture customized knee implants, both the femur and tibia, for each patient. No two are alike. Our femoral and tibial implants are individually sized and shaped to fit to each patient’s unique anatomy, offering advantages we believe are not achievable with “off-the-shelf” knee implants.

ConforMIS Customized Knee Implants

Our customized patient-specific knee implants are designed to accommodate all stages of osteoarthritis of the knee. Coupled with a complete set of personalized instrumentation, our knee replacement options build upon established principles in orthopedics to address the compromises common with traditional “off-the-shelf” implant designs that have led to patient dissatisfaction.

There’s a reason 1 in 5 patients are not satisfied with their traditional total knee replacement.iIn traditional knee replacement surgery, the surgeon selects an “off-the-shelf” implant from a range of standard fixed sizes, and then has to make the necessary adjustments to fit the implant to the patient during the procedure. Because off-the-shelf knee replacements aren’t designed to your specific anatomy, surgeons have to compromise on implant fit. This compromise may result in having implant overhang (implant hangs over the bone) or underhang (the implant is too small, leaving the bone exposed and uncovered). It could also result in an implant that isn’t aligned properly.

Clinical studies have demonstrated that these compromises on fit can cause residual pain after surgery. At ConforMIS we design partial and total knee implants to fit the patient, not the other way around. We combine proven elements of standard knee replacement with our iFit Image-to-Implant® technology to create customized knee implants and surgical instrumentation that are designed to fit your knee’s natural shape and curves.

Image-to-Implant® Process

iFit Image-to-Implant® software is the technology platform that allows for the design of our patient-specific implants and instrumentation. Proprietary algorithms convert a CT scan of the knee to a 3D model by mapping the articular surface of the joint and defining the area of disease. That 3D model is used to design the implant and the surgical instrumentation that is unique to each patient

The iTotal CR Knee Replacement System is intended for use as a total knee replacement in patients with knee joint pain and disability whose conditions cannot be solely addressed by the use of a prosthetic device that treats only one or two of the three knee compartments, such as a unicondylar, patellofemoral or bicompartmental prosthesis. 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.

The Indications for Use include:

  • Painful joint disease due to osteoarthritis, traumatic arthritis, rheumatoid arthritis or osteonecrosis of the knee.
  • Post traumatic loss of joint function.
  • Moderate varus, valgus or flexion deformity in which the ligamentous structures can be returned to adequate function and stability.
  • Failed osteotomies, hemiarthroplasties, and unicondylar, patellofemoral or bicompartmental implants.
  • 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. Caution: Federal law restricts this device to sale by or on the order of a physician.

i: According to a study of 1,703 patients published by Bourne in 2009 in the peer-reviewed journal Clinical Orthopaedics and Related Research (In this study entitled Patient Satisfaction after Total Knee Arthroplasty: Who is Satisfied and Who is Not?, “the overall satisfaction question was used to determine a two category satisfaction outcome by combining patients who answered very dissatisfied, dissatisfied, or neutral into one group, and patients who answered satisfied or very satisfied into the second group.”) ii: Mahoney, et al; Overhang of the Femoral Component in Total Knee Arthroplasty: Risk Factors and Clinical Consequences.

iii: In a study by W. Kurtz titled “Patient-Specific Knee Replacement Implants Preserve Bone and Decrease Blood Loss & Swelling” presented at the 2013 BASK Annual Meeting, comparing 66 iTotal patients with 66 patients receiving one off-the-shelf implant brand (Zimmer NexGen), thickness of the femoral (distal and posterior medial/lateral), and tibial (medial/lateral) resections were measured intra-operatively. The average total of all bone resection measurements for iTotal was 27% (14mm) less than for the off-the-shelf total knee. Additionally, the total thickness of the iTotal implants was 25% (15.7mm) thinner on average than the off-the-shelf implants
