Back in 2003 Dr. Douglas Dennis and Dr. Richard Komistek received The Coventry Award for their paper that studied in vivo kinematics after total knee arthroplasty. I. This study they found that off the shelf total knee replacements do not replicate normal kinematics.
Up until now, no knee replacement implant has been able to come close to replicating the natural kinematics of a knee. In 2015 Dr. Richard Komistek and Dr. Harold Cates presented a paper at the International Congress for Joint Reconstruction that put the custom Conformis iTotal Knee Replacement in a head to head comparison with two different off the shelf knee replacement designs. The full paper is attached to this post.
Patients were asked to perform a maximum knee bend and to rise from a chair while inside a state of the art mobile fluoroscopy unit that was taking video as the patients went through their movements. These videos were then converted to a three-dimensional view and were analyzed by the researchers.
100% of the patients who had received the Conformis knee achieved weight bearing range of motion greater than 90 degrees. The patients who had received the off the shelf knee were able to achieve weight bearing range of motion greater than 90 degrees only 76% of the time.
93% of patient’s who received the Conformis knee achieved a normal rollback and the off the shelf knees achieved normal rollback only 52% of the time for one off the shelf knee and 76% for another brand of off the shelf knee replacement.
Lastly, the patients who received the customized Conformis Knee Replacement had the lowest incidence of the anterior slide while the patients performed a deep knee bend.
All of this shows just how much ConforMIS can give a person a knee that more closely performs as their knee did before surgery. ConforMIS respects each person's shape and size, and this has proven to be beneficial to the people who are in need of total knee arthroplasty.
