Mechanical Prosthetic Knees
Mechanical knees all use a mechanical hinge to replace your knee joint. How quickly or easily the hinge swings is often controlled by friction, some type of hydraulic system or a locking mechanism. Here are some examples of mechanical prosthetic knees:
The 3R80 by Ottobock
Make a splash! Wear your prosthesis in the pool, shower, or at the beach. From the versatile 3R80 shown above to the 3WR95 and Aqualine system featured here, we provide multiple options ideal for both below-knee or above-knee amputees.
No matter whether it’s chlorine to bath water, moisture won’t wear on the Aqualine system. With added traction on the foot, you’ll feel confident and secure getting out of the shower or walking by the pool.
The 3R80 with its unique rotation hydraulics principle is now also approved for prosthesis wearers with a body weight of up to 150 kg (330 lbs). With the 3R80, both the stance and the swing phase are controlled by the hydraulics. For example, walking down stairs step-over-step and walking down inclines are effectively supported by closely approximating a physiological gait pattern, even at various walking speeds.
