Zimmer LPS Knee

Prolong Highly Crosslinked Polyethylene generates an 83% wear reduction compared to conventional polyethylene.⁵

The LPS-Flex Mobile Bearing Knee provides an anteriorly positioned pivot near the entry point of the anterior cruciate ligament (ACL).

The LPS-Flex Mobile Bearing Knee is supported by both clinical history and published study results.
