What is the primary function of the knee during transtibial swing phase when utilizing hydraulic technology?

In transtibial prosthetics that utilize hydraulic technology, the primary function of the knee during the swing phase is to control the rate of flexion. Hydraulic knees are designed to mimic the natural dynamics of movement and to provide a more fluid and adaptive response to changes in gait and terrain.

During the swing phase of ambulation, the knee must flex to allow for the proper clearance of the prosthetic limb from the ground. Hydraulic systems achieve this by regulating the amount of hydraulic fluid that flows within the mechanism, allowing for a smooth and controlled flexion as the limb moves forward. This adaptability helps to ensure a safe and efficient gait pattern by allowing the user to maintain balance and control while walking.

Controlling the rate of flexion is particularly important for providing a natural walking experience. If the knee flexes too quickly or too slowly, it can affect the overall balance and stability of the individual. Therefore, the hydraulic system is engineered to allow for a customizable response, accommodating the user’s gait and enhancing their mobility.

This adaptability sets hydraulic knees apart from other types of knee mechanisms, which may not offer the same level of control over movement dynamics during the swing phase.
