Zimmer Rolls Out New U.S. Version of NexGen Knee

Zimmer Holdings, Inc. recently launched its NexGen LPS-Flex Mobile Bearing Knee with Prolong Highly Crosslinked Polyethylene (XLPE) in the United States.

According to the Warsaw, Ind.-based orthopedic company, new implant provides a “revolutionary” anteriorly positioned pivot near the entry point of the anterior cruciate ligament, replicating the anatomic center of knee rotation.

The LPS-Flex Mobile system is backed by more than ten years of clinical history in Europe and Japan. Since the system’s launch, more than 130,000 LPS-Flex Mobile knees have been implanted worldwide.

“Our Prolong Highly Crosslinked Polyethylene provides a number of clinical advantages, including reduced wear and delamination resistance,” said Jeff McCaulley, president of Zimmer’s reconstruction division.”Applying this exciting material to our already successful NexGen LPS-Flex Mobile Bearing Knee System represents a major step forward in mobile bearing design.”

According to McCaulley, the firm’s testing showed that the LPS-Flex Mobile with Prolong Polyethylene system demonstrated an 83 percent wear reduction compared to conventional polyethylene.

Zimmer was the first company to launch XLPE more than nine years ago for the NexGen Fixed Bearing system. Since its launch, the blend specifically formulated for the knee has been used in more than 450,000 implantations worldwide.
