The EVOLUTION Medial-Pivot Knee System allows normal anatomic motion and natural function by replacing the native structure of the knee and provides a highly-conforming surface on the medial side. It is designed to answer the limitations of traditional implants by delivering superior flexion stability, quadriceps efficiency, and wear-limiting design characteristics. The EVOLUTION Medial-Pivot Knee System is built upon a legacy of 95% patient satisfaction with 98.8% survivorship at 17 years.

Medial Pivot Design Features

• Flexion Stability
• Anatomic Motion
• Wear-limiting design
• Enhanced quadriceps efficiency achieved through longer constant flexion radius with more posterior, medial dwell point
• High Medial Conformity and constant radius spherical condyles
• Driven through a stable medial compartment and a mobile lateral compartment that rotates or pivots about the medial
• Enabled through a maximized contact area and repeatable motion path that minimizes contact stresses

Cruciate Sacrifice Design (CS)

The EVOLUTION Medial-Pivot inserts feature 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.
