Evolution® Medial-Pivot Knee System – Primary

The medial-pivot insert is designed to allow normal motion and natural function by replicating the native structure of the knee and providing a highly-conforming surface on the medial side.

MicroPort Orthopedics

MicroPort Orthopedics Advance® medial-pivot knee system was launched in 1998, making it the first medial-pivot knee system available on the market. A culmination of years of research and design by Wright Medical and Dr. J. David Blaha resulted in a truly unique knee replacement design. With over 25 years of documented usage, Meditsea Orthopedics line of Medial-Pivot products have been used in over 1,000,000 cases in 70 countries worldwide. Patients reported satisfaction with a Medial-Pivot prosthesis is 95%, while the Medial-Pivot design has achieved outstanding clinical success worldwide, with documented 98.8% survivorship at 17 years.

A recent study also confirmed higher patient satisfaction when knees are balanced with a tighter medial compartment.

Meditsea Orthopedics provides a full Evolution® medial-pivot contiuum of care, offering a primary knee with both cemented and cementless options. A stemmed primary for both the femur and tibia, and a revision portfolio featuring a CCK with medial-pivot articulation.

Medial-Pivot Knee Systems

Evolution® Knee Systems

The Evolution® medial-pivot knee system delivers superior flexion stability, anatomic motion, and wear–limiting design.

Stability

Traditional knee replacements have been shown to exhibit anterior/posterior translation, which decreases stability and can cause early revisions. Through medial ball-in-socket articulation, coupled with lateral mobility, the Evolution® medial-pivot knee system has been formulated to maximize stability throughout the range of motion

Quadriceps efficiency

The Evolution® medial-pivot knee system enhances quadriceps efficiency and reduces the quadriceps avoidance found in traditional knee replacements. A study has shown that by enhancing quadriceps efficiency, proprioception may also be increased.

Cruciate sacrificing design

The Evolution® medial-pivot insert features an anterior raised lip, to replicate the function of the PCL, and a posterior raised lip, to replicate the function of the ACL, acting like an ACL-PCL substituting knee.

Natural knee movement

In-vivo long-term clinical studies have consistently shown that medial-pivot design achieves equal or higher degrees of flexion than traditional posterior stabilized (PS) knee design, with an average of 124°.

WHAT SURGEONS ARE SAYING ABOUT MICROPORT ORTHOPEDICS, THE MEDIAL-PIVOT IMPLANT, AND ROBOTIC PLATFORMS

“The Evolution® Medial-Pivot Knee is a stable knee, but this advanced robotic technology offers a way to make a great knee even greater.”
