High Flex Knee Replacement Overview

High Flex Knee Replacement
Prosthetic Knee Accommodates a Higher Degree of Bending for Total Knee Replacement Recipients

For approximately 21 million Americans who suffer from osteoarthritis, pain has become a part of every day life. In some cases, total knee replacement may be the best option for relief. But many individuals may not take that step, fearing further limitations in their daily activities. A new total knee replacement implant can help put those concerns to rest.

The NexGen® Complete Knee Solution LPS-Flex Fixed Bearing Knee offers a new option for those osteoarthritis patients who want to continue their active lifestyle after total knee replacement. For patients with the ability and desire, the Flex Fixed Knee is designed to accommodate resumption of deep knee bending activities. Early diagnosis, good preoperative flexibility and appropriate rehabilitation (physical therapy) can help a patient’s chance for success.


The Flex Fixed Knee replacement is the first knee specifically designed to safely accommodate flexibility of up to 155 degrees. Many activities of daily living require good range of motion, such as climbing stairs (75-140 degrees) and sitting in a chair (90-130 degrees). Hobbies such as gardening and golfing or activities such as kneeling for prayer and sitting cross-legged can demand an even greater degree of bending. Generally, knee replacements have been designed to accommodate flexibility up to 125 degrees.

This information is part of a public awareness campaign, “Keeping pace with life,” designed to educate patients about the new Flex Fixed Knee as an option for total knee replacement. The campaign goal is to provide patients with information and insight into the leading edge treatment for joint replacements to help them make educated decisions about their course of treatment.
