Different by design
Different by design At Össur, we do things differently. The RHEO KNEE design is unique in the MPK market, in that its operating principle is not based on hydraulic technology. Instead it is operated by what could be described as an electronic brake whereby resistance is continually adapted to the user s needs and situation. This technology is termed Magnetorheologic which is highly responsive and proven technology, pioneered by the aerospace, defense and automotive industries. It utilises electromagnetic forces to rapidly alter the viscosity of the magnetic fluid in the knee. This allows an almost instantaneous shift from the high resistance required for stability in stance phase to the low resistance needed for a dynamic, free swing phase, simulating the natural function of the physiological knee joint. Clinical evidence conducted with the RHEO KNEE compared to previous versions and to hydraulic MPKs, showed significant improvements in users ability to walk further, faster, with less exertion. NEW FEATURES WEATHERPROOF for use in wet and/ or humid environments*. STRONGER extension assist for faster and more natural swing extension. NEW Össur Logic App for clinicians and user's, for easy access to data and the programming of settings. SMOOTHER transition from stance to swing. ADJUSTABLE swing initiation settings. HIGH RELIABILITY RECORD with less than 2% returns since January 2014. ADVANCED FUNCTIONALITY provided by the RHEO KNEE XC facilitates stair ascent, running and cycling. *Do not submerse, nor expose to chlorinated or salt water.

RHEO KNEE 3 Stability and dynamics, whatever the weather Now weatherproof, stronger, smarter and easier to use, the technology behind this second-generation RHEO KNEE 3 has been significantly upgraded. Designed for everyday use, it delivers confidence-boosting stability and dynamic, natural gait for increasingly active people who want to enhance their mobility and return to regular activities. ÖSSUR DYNAMIC The choice of prosthetic solution is critical in supporting people to regain a dynamic lifestyle and engage in the challenges of everyday life from shopping and gardening to light work and walks. RHEO KNEE 3 is part of Össur Dynamic Solutions, carefully designed to meet the needs and aspirations of increasingly active people who want to return to their preferred regular activities. RHEO KNEE 3 WITH PRO-FLEX : THE DYNAMIC DUO For the most dynamic RHEO KNEE experience, we recommend the new RHEO KNEE 3 with our new Pro-Flex foot. Pro-Flex has an increased ankle range of motion of 82%, with nearly twice the energy return of a conventional carbon fiber foot (when compared to Vari-Flex). This, combined with a more natural center of pressure helps reduce sound side impact by 11%, and knee varus moment of 15%, helping to tackle the principle causes of Osteoarthritis. Multiply this load reduction over a lifetime of steps and the potential health benefits are numerous.
RHEO KNEE XC Go anywhere Taking it to the next level, RHEO KNEE XC is the ideal companion for the more demanding users who want to engage in high-impact, ambitious endeavors. It has the same weatherproof advantage and instinctive stability as RHEO KNEE 3, plus advanced and unrivalled functionality that facilitates stair ascent, running and cycling. ÖSSUR DYNAMIC The aspirations of people who are fit and agile may increase in line with their confidence. Keen to return to a demanding job, for example, they may also want to take up high-impact activities. Critically, prosthetic solutions should address the forces generated by such activities. RHEO KNEE XC is part of Össur Impact Solutions, carefully designed to meet the ambitions of demanding users who engage in high-impact endeavors. RHEO KNEE XC WITH PRO-FLEX XC: THE PERFECT COUPLE For an optimal RHEO KNEE XC experience, we recommend combining RHEO KNEE XC with Pro-Flex XC. Pro-Flex XC offers excellent vertical compression, all-terrain compliance and toe-off energy for active users. Pro-Flex XC is also compatible with unity for optimising volume control, socket stabilisation and proprioception.
