Knee

The MicroPort Orthopedics medial-pivot knee system features a highly conforming medial side to reproduce a healthy knee’s stability and motion.

The Evolution® medial-pivot knee is uniquely engineered to reproduce a healthy knee’s stability and motion. The medial-pivot knee features a highly conforming medial side that results from a constant radius design, reproducing the natural function and stability of the ACL and PCL. This design is unique from every other less conforming traditional knee system. With a stable, pivoting medial side and a lateral side that rolls forward or backward throughout flexion, the Evolution® knee system is designed to feel and function like a natural knee.

The medial-pivot knee system enhances quadriceps efficiency and reduces the quadriceps avoidance found in traditional knee replacements. By enhancing quadriceps efficiency, the patient can have increased proprioception and a more normal feeling knee.¹

Patients can tell a difference according to a peer-reviewed study that examined patient satisfaction among patients who underwent bilateral staged total knee replacement with different prostheses. A Medial-Pivot design was preferred equally to an ACL-PCL retaining prosthesis and preferred more than all other designs (CR, PS, and Mobile-Bearing).²
