CR Version of High-Flexion Knee

Zimmer has applied for patent protection on this "minus size” femoral concept. NexGen CR-Flex, the product of Zimmer Holdings, Inc. (Warsaw, IN, USA), will enable surgeons who prefer a CR design to offer patients a high flex knee. Previously, Zimmer's LPS-Flex design addressed only the requirements of surgeons who prefer a cruciate sacrificing, or posterior-stabilized system.

"With a cruciate retaining design, a surgeon must be able to balance the tension on the ligaments and tendons that holds the knee in proper alignment,” said Dr. Kim Bertin, an orthopedic surgeon in Salt Lake City (UT, USA), who worked with Zimmer to develop this new design. "The NexGen CR-Flex allows the surgeons to achieve soft-tissue balancing without the need to make additional bone cuts or ligament releases.”
