Transfemoral Above-Knee Componentry
At Real Life Prosthetics, we understand that life after amputation is a journey, physically, emotionally, and spiritually. You are not just receiving a device, you are gaining a partner who will walk with you every step of the way.
The right prosthetic knee can make a real difference in daily life by offering better stability on uneven ground, smoother movement for walking, improved safety to reduce falls, and energy savings so you do not tire as quickly. Your Real Life Prosthetics clinician will work closely with you to explore the range of prosthetic knees available and help determine which option best supports your mobility goals.
Understanding the types of prosthetic knees:
Microprocessor Hydraulic Knees
-
Use sensors and microprocessors to adjust swing and stance in real time.
-
Provide smoother, more natural walking and adaptive stability on different terrains.
Mechanical Knees
-
Use a fixed or hydraulic system without electronic sensors.
-
Rely on mechanical design (single-axis or polycentric) to control swing and stance.
-
Examples of these are: 3R85 Dynion, KX07, Mauch, and Prosedo
Powered Knees
-
Actively assist in knee flexion and extension using motors or energy-return systems.
-
Reduce effort during walking, stair climbing, and standing.
-
Examples of these are: Intuy and Power Knee
Safety Knee is designed for lower-activity users or those needing extra fall protection, often includes mechanical locks or controlled resistance to prevent unintended knee flexion.
Polycentric Knee uses a multi-bar linkage system to mimic natural knee motion, providing increased stability, smoother swing, and higher ground clearance during walking.
