About ConforMIS

“ We believe that optimizing implant fit and performance requires a patient-specific approach. ”
No two knees are the same. No two ConforMIS knee implants are either.


Orthopedics has historically been a game of averages. Average sizes. Average shapes. Average results. No more.

We start with a simple idea: make the implant fit the patient rather than force the patient fit the implant

ConforMIS does something that we believe no other knee implant manufacturer has done. We put the patient at the center of implant design. By combining advanced 3D imaging technology with the latest manufacturing capabilities, we customize each and every implant to the patient’s unique size and shape.

We are a medical technology company that uses our proprietary iFit Image-to-Implant technology platform to develop, manufacture and sell joint replacement implants that are individually sized and shaped, which we refer to as customized, to fit each patient’s unique anatomy. We believe we are the only company offering a broad line of customized knee implants designed to restore the natural shape of a patient’s knee. In recent clinical studies, iTotal CR, our cruciate-retaining total knee replacement implant, demonstrated superior clinical outcomes, including better function and greater patient satisfaction compared to traditional, off-the-shelf implants.
