Customised Knee Replacement Surgery

Customised Knee Replacement

Treatment and Rehabilitation

Customised knee replacements are specifically designed for your knee to give you better results. Using a 3D model of your knee created from a CT scan, the new ConforMIS knee system is tailor-made to your exact requirements to give you the best fit, rotation, alignment and satisfaction.

The ConforMIS knee system is generally not available through the NHS but is available privately and is funded by nearly all major healthcare insurers in the UK. It is also available to self-pay patients.

Understanding your knee

To understand the benefits of the ConforMIS personalised approach, it’s important to understand the anatomy of your knee.

Your knee joint is formed by the intersection of the femur (thigh bone), the tibia (shin bone) and patella (knee cap). These bones form three “compartments” or sections.

Osteoarthritis (OA) is a degenerative joint disease characterised by the breakdown and wearing away of cartilage causing the bones to rub together and result in pain. It can affect all of the knee or just parts, depending on the severity.

A partial knee replacement (PKR) is an option for people who have OA in one or two compartments. A total knee replacement (TKR) is an option for people with OA in all three compartments.

There has to be a better way

Knee replacement is a very common procedure. Despite its proven history, studies show that as many as 1 in 5 patients report they are not satisfied with the results of their total knee replacement.

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

To provide 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:

 

  • Individualised 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.

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.

Customised 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.
