The original medial-pivot knee design
The unique design and successful clinical heritage of MicroPort® Orthopedics’ medial-pivot knees sets the EvolutionTM Knee System apart from the competition. A legacy of 98.8% survivorship and 17 years and 95% patient satisfaction supports the ability of MicroPort® Orthopedics’ medial-pivot designs to restore stability and normal kinematics. This helps surgeons to achieve favorable, reproducible, and long-lasting outcomes for their patients.1-4
"They return back to their function much faster. I think that this is, one, because we've gotten better at pain control, but I also think that it's gotten to the point with the medial pivot, that we're recreating the kinematics of their knee so accurately that it really is almost a resurfacing procedure, as opposed to us actually truly replacing the knee."
Dr. Joseph Assini MD, Englewood, CO
"The advantage of the Medial-Pivot Knee lies in its ability to mimic the kinematics of a healthy knee. It’s as simple as this! All of the surrounding soft tissue of the knee is adapted to a specific sequence of movements. If you keep it that way, the knee works well. In addition the medial ultra-congruent compartment gives the stability throughout the range of motion. Stability and physiological kinematics are the key."
Dr. Matthias Schmied MD, Switzerland
"My patients that have had the Evolution Knee seem to get back to a normal degree of function more rapidly."
Dr. David Backstein MD, MEd, Toronto, ON
"The “Ball-in Socket” design of Evolution® Knee can reproduce knee motion that is compatible with “Mobility” and “Stability” even for the inexperienced surgeons, even in severe OA patients, achieving a high level of patient satisfaction."
Osamu Nishiike MD, Kushiro, Japan
Primary medial-pivot knee systems
The MicroPort® medial-pivot knee system now stands on over 20 years of clinically demonstrated history with its first to market medial-pivot design that was built on the latest kinematic evidence of the natural stability and motion of the knee.1 Its innovative design aims to restore function by replicating natural motion and AP stability and to address some of the common problems seen with traditional designs, such as anterior knee pain and quadriceps avoidance.
Revision medial-pivot knee systems
MicroPort® Orthopedics revision knee systems are built on a 20-year clinical heritage of patient satisfaction and survivorship. The Evolution® revision system is the first revision knee system that maintains the proven kinematic benefits of a medial-pivot design, while also offering surgeons intra-operative flexibility to meet all patient needs.
Celebrating 20 years of innovation, MicroPort® Orthopedics employees as well as surgeons who utilize the medial-pivot knee system share their experience with the innovative knee replacement design over the last 20 years
