Microprocessor Knees
Ossur RHEO Knee: A device designed for transfemoral amputees, this knee acclimates to an amputee’s walking manner and surroundings. Learning how the amputee moves, the knee enables the wearer to effortlessly traverse slopes, stairs, and tight spaces, while walking at varying speeds with poise.
Ottobock C-Leg® 4: The C-Leg® 4 is Ottobock’s most recent improvement to its original C-Leg, which debuted in 1997. Improvements include advanced stumble recovery, a control feature that improves the transition to swing phase and makes walking backwards safely possible, and precise adjustment at every moment of every step. Plus, it’s a weatherproof knee, meaning that it is splash resistant if caught in a rain storm.
Ottobock Genium® X-3: With this leg prosthesis system, the virtually natural replication of the physiological human gait is possible. The Genium® X3 opens up entirely new possibilities, including showering or going swimming. Since the system is water and corrosion-resistant, it stands up to any ambient conditions. Walking backwards, climbing stairs step-over-step or walking at changing speeds and with different stride lengths – the joint is intuitive to use and flexible in adapting to the circumstances. The running mode, which developed especially for sports, provides the settings needed for jogging or running. Overall, the Genium® X3 offers five additional configurable modes.
Ottobock Kenevo Microprocessor Knee: The lightest-weight microprocessor knee currently available, its five essential functions are fine-tuned to keep low-activity patients safe and feeling secure as they go about their daily activities or challenge themselves through the rehab process. Kenovo automatically detects when the wearer begins to sit down. It adjusts the hydraulic resistance so the knee joint provides progressive support during sitting and automatically detects when the wearer begins to stand up. If the user cannot complete this act in a single motion, Kenevo provides support by locking the joint in the flexion direction. It also offers a range of programmable stance stability options that can be customized to support each patient’s individual capabilities.
Blatchford Linx: This microprocessor knee for K-3 amputees is equipped with integrated sensors, which continually analyze data, adjusting the hydraulic technology to seamlessly align the leg for the next step. This ensures fast adjustment times and easy navigation of slopes and steps, allowing the user to think about where they are going, rather than how they are going to get there. Features include varying levels of stance resistance to optimize safety, a cycling mode and fixed angle flexion lock mode, and knee flexion to 130°. The result is a walking experience that is closer to natural than ever before.
ALLUX 2: The microprocessor controlled hydraulic cylinder provides a smooth swing phase at various walking speeds. Finely tuned response coupled with 4-Bar linkage allows the user to walk with a natural gait and to smoothly walk down stairs and slopes step-over-step. In case of stumbling, the microprocessor immediately increases the hydraulic resistance to prevent the knee from sudden buckling. A knee flexion angle of 180° enables activities like biking, kneeling, or changing shoes. The ALLUX is suitable for low active users as well as long trans-femoral amputees/knee disarticulation.
