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 rotation1,2
- Anterior pivot design leads to lower patellofemoral forces that lead to anterior knee pain, patellar subluxation and dislocation, component wear, damage, and loosening3,4
- 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
- Increased contact area/lower contact stresses
- Frontal plane conformity ratio
|LPS-Flex Mobile Bearing Knee||1:1|
|DePuy P.F.C* Sigma Rotating Platform||1.03:1|
- Sagittal plane conformity ratio at extension and low angles of flexion5
|Zimmer NexGen LPS-Flex Mobile Bearing Knee||1.005:1|
|DePuy P.F.C* Sigma Rotating Platform||1.02:1|
- Femoral radii are matched to size-specific articular surfaces
- Allowing only unidirectional rotational motion potentially reduces cross-shear and consequent wear6
