WillowWood One Transtibial System
PrintThe WillowWood One TT system adapts socket technology from the transfemoral version of the system, and makes it available for transtibial applications. The transtibial socket system, for use with either elevated vacuum or suction, delivers an airtight seal, an internal sleeve, and socket security.
Components of the WillowWood One TT system include an Alpha Duo® Liner, a One Gel Sock, an optional LimbLogic, a flexible inner socket, a One Sleeve, and the One Link. Together, these components create an airtight system that moves with an amputee’s residual limb for reliable suspension and comfort.
Throughout development, goals for the transtibial system were to make it comfortable to wear, control pistoning, facilitate a comfortable walking gait, and be compatible with various amputee activity levels. Clinical testing has shown unprecedented seal durability and compatibility with various activity levels and ages. Numerous amputees who tested the system reported feeling a closer fit on their residual limbs and experiencing an improved sense of security from the WillowWood One TT system over their previous prostheses.
