Transfemoral Prosthesis

Here’s a breakdown of Transfemoral Prosthesis (Above Knee Leg) components and function:

Socket: The socket is custom-made to fit the residual limb snugly and comfortably. It is the interface between the limb and the prosthesis, providing support and stability.

Knee Joint: The prosthetic knee is a critical component that allows the user to bend and straighten the leg. There are various types of knee joints, including:

Mechanical Knees: These are basic knees that use a simple hinge mechanism.

Hydraulic Knees: These use fluid dynamics to provide smoother and more controlled movements.

Shank: The shank is the section of the prosthesis that connects the knee to the prosthetic foot. It can be endoskeletal (with an internal support structure and cosmetic cover) or exoskeletal (with a hard outer shell).

Suspension System: This system keeps the prosthesis securely attached to the residual limb. Common methods include suction, vacuum, pin-locking systems, and belts or straps.

Prosthetic Foot: The foot component varies based on the user’s needs and activity level. Options range from simple, non-articulated feet to advanced, energy-storing feet that mimic the movement of a natural foot.

Control Mechanisms: Depending on the prosthesis, there may be different control mechanisms to assist with movement and stability. For example, microprocessor knees can provide real-time adjustments based on the user’s gait and terrain.
