Knees vary in size and shape. Even your own two knees are different. In a traditional knee replacement, however, the surgeon selects an “off-the-shelf” implant from 6-10 standard sizes and makes the necessary adjustments to fit the implant during the procedure.

Because off-the-shelf implants aren’t designed to your specific anatomy, surgeons often have to compromise on implant fit, rotation, and alignment. These compromises can cause pain or discomfort after surgery and help explain why 1 in 5 patients aren’t satisfied.

Making it personal instead of off-the-shelf

The first knee replacement that fits only one knee. Yours.

To provide our patients with better results, ConforMIS has developed the only customized total knee replacement that is designed specifically for your knee.

This patient-specific approach offers unique advantages not possible with traditional, off-the-shelf implants:

  • Individualized fit that virtually eliminates sizing compromises common with off-the shelf implants and often associated with pain after surgery.
  • Designed to follow the shape and contour of each patient’s knee, which provides an increased potential for a more natural feeling knee.
  • Maintains the patient’s natural joint lines to avoid instability, a common cause of patient dissatisfaction

 

Better fit leads to less pain

ConforMIS implants are specifically designed to fit your knee, avoiding sizing and positioning compromises common with off-the-shelf implants that can lead to long-term painful outcomes. Our implants are also designed for optimal bone preservation.

Designed for a more natural feeling knee.

ConforMIS implants are designed to mimic the natural shape of your knee, which plays an important role in the way your knee bends and extends. By restoring the natural shape of your knee rather than replacing it with the standardized geometry of off-the-shelf implants, your knee may feel more like your natural knee.

Stability more closely matched to the normal knee

Many patients complain that their knee feels wobbly after knee replacement surgery. This feeling is formally known as mid-flexion instability. Off-the-shelf knee implants aren’t designed to match the natural offset joint line that most patients have. Instead, they flatten the offset to the same height, which can lead to mid-flexion instability.

ConforMIS implants maintain the patient’s medial and lateral joint lines, which allows for a more stable knee after surgery.

Customized just for you

ConforMIS iFit® image-to-implant® technology converts a CT scan of your knee into a 3D model and then designs an implant that’s unique to you. This fully automated process ensures that your implant is made for your knee, and only your knee.

The iTotal CR Knee Replacement System (KRS) 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 compartments. The iDuo G2 Knee Repair System (KRS) is intended for use in patients with severe knee joint pain and disability whose conditions cannot be solely addressed by the use of a prosthetic device that treats only a single knee compartment. The iUni G2 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.These implants are intended for cemented use only.
