No two knees are the same. No two ConforMIS knee implants are either.

Knee replacement technology has made many great strides over the years, and today it is a very common procedure. However, knee implants have always been designed to a standard shape, with a limited range of size options. The result is designs that force surgeons to make compromises that can negatively impact the patient.

Close Isn't Good Enough

At ConforMIS we believe that optimizing implant fit and performance requires a patient-specific approach. Our mission is to provide best-in-class, patient-specific implants and instrumentation that offer unique advantages over traditional orthopedic implants. 

We start with a simple idea: make the implant fit the patient rather than forcing the patient to fit the implant. Our implants are individually sized and shaped to fit to each patient’s unique anatomy, providing precise anatomic fit and preserving healthy tissue. Our disposable, patient-specific instrumentation also eliminates many of the tools required for traditional orthopedic surgery and simplifies surgical technique. By combining our personalized implants with our unique instrumentation, a surgeon is able to provide a customized solution that is designed to preserve more of the patient's joint line and natural curvature.  

Our Company

ConforMIS, Inc. is a privately held medical device company based in Bedford, MA. It was founded in 2004 to provide dramatic advancements in patient care by utilizing imaging technology to create personalized, patient-specific implants and instrumentation. 

ConforMIS transforms traditional CT data into patient-specific implants and instrumentation employing two related image-to-implant™ technology platforms: 

  • iFit® technology converts CT data into implants that are precisely sized and shaped to conform to the unique 3D topography of an individual joint. 
  • iJig® instrumentation utilizes the same data to create cutting and placement guides that eliminate the need for manual sizing, reduce surgical time and trauma, and improve reproducibility. 

Both platforms are supported by proprietary, intellectual property consisting of more than 250 patents and pending patent applications that span imaging software, image processing, implant design, surgical techniques and orthopedic instrumentation. The technology and patent portfolio is applicable to all major joint systems. 

To date, ConforMIS has developed a comprehensive line of minimally traumatic implant solutions to address all stages of knee osteoarthritis, the most common reason for knee replacement surgery. Each of these devices has been cleared for marketing by the US Food and Drug Administration.
