Product Overview
A Move Forward in Mobile Bearing Design
The Zimmer NexGen LPS-Flex Mobile and LPS-Mobile Bearing Knees provide an anteriorly positioned pivot near the entry point of the anterior cruciate ligament (ACL).
• An anterior pivot at the ACL site replicates the anatomic center of rotation
• Anterior pivot design leads to lower patellofemoral forces that lead to anterior knee pain, patellar subluxation and dislocation, component wear, damage, and loosening
• An anterior stop on the tibial plate prevents bearing spin-out and allows 25 degrees of unimpeded internal/external rotation
The LPS-Flex Mobile Bearing Knee Femoral Component has an enhanced cam/spine mechanism that is designed to provide stability at up to 155 degrees of active flexion.
• Deepened patellar groove delivers smooth patellar tracking, relieves pressure on the patella, and reduces forces that may cause patella clunk, pain, and premature wear
• Subluxation resistance increases at deep flexion angles as the cam moves down the spine
• Extended posterior flanges safely accommodate tibio-femoral contact during deep flexion
Wear
• Increased contact area/lower contact stresses
• Frontal plane conformity ratio

DePuy P.F.C* Sigma Rotating Platform 1.03:1
• Sagittal plane conformity ratio at extension and low angles of flexion

• Femoral radii are matched to size-specific articular surfaces
• Allowing only unidirectional rotational motion potentially reduces cross-shear and consequent wear
