Modular Knee Joint with Rotary Hydraulic
As a prosthesis wearer, you want to be confident that your knee joint meets your daily requirements and supports changing walking speeds.
With the waterproof 3R80 knee joint, 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. This allows users to manage their everyday lives with determination at their own pace.
