Zimmer Holdings, a provider in musculoskeletal care, has launched NexGen LPS-Flex mobile bearing knee with Prolong Highly Crosslinked Polyethylene (XLPE) in the US.
The LPS-Flex Mobile Bearing knee provides an anteriorly-positioned pivot near the entry point of the anterior cruciate ligament (ACL), replicating the anatomic center of knee rotation.
Zimmer Reconstructive division president Jeff McCaulley said their XLPE provides a number of clinical advantages, including reduced wear and delamination resistance.
"Applying this exciting material to our already successful NexGen LPS-Flex Mobile Bearing Knee System represents a major step forward in mobile bearing design," McCaulley said.
Zimmer said the LPS-Flex Mobile with Prolong Polyethylene system demonstrated an 83% wear reduction compared to conventional polyethylene, during in vitro wear simulator testing.
