It’s an unfortunate fact that up to 20% of patients who undergo traditional knee replacement are unhappy with their results due to persistent pain in the joint—even after surgery. This chronic pain typically comes from a variety of sources, including instability, stiffness, or improper fit and sizing of the implants. AOC has the only local surgeon, Dr. Matt Barber, who provides a solution to some of these potential problems with the ConforMIS iTotal Knee Replacement.
Dr. Barber knew there had to be a way to achieve a higher success rate for total knee replacement. He found that ConforMIS uses 3D printing technology to fabricate patient-specific implants designed to perfectly match an individual’s anatomy and replicate the form and function of his or her original knee. By using a CT scan of the knee, ConforMIS’ computer software can calculate the shape and position of the implant that works best and restores the proper alignment of the leg.
While there are other technologies available (such as robotic assistance), they still use the conventional off-the-shelf knee implants, thus still having the potential for anatomic mismatches. ConforMIS’s total knee and partial knee replacements, on the other hand, are patient specific, producing a comfortable fit and allowing more natural movement with a quicker recovery time. In addition, the femoral component of this implant is thinner than those involved in a traditional total knee replacement, preserving more of the patient’s bone, which can be beneficial if other treatments are ever needed.
ConforMIS iTotal Knee Replacement is the first FDA-approved custom total knee replacement system for people who have osteoarthritis of the knee and is the only system of its kind designed for each individual patient’s needs.
