The socket is a crucial part of the above knee prosthesis as it provides a customized and secure connection between the residual limb and the prosthesis. It is designed to fit the unique shape and contours of the individual's residual limb, ensuring comfort and stability during movement.

The knee joint in an above knee prosthesis is responsible for replicating the natural movement of a knee. It allows for flexion and extension, allowing the user to walk, climb stairs, and engage in other physical activities. The choice of knee joint depends on factors such as the user's activity level, lifestyle, and personal preferences.

The foot component of the prosthesis provides support, shock absorption, and propulsion during walking or running. Different types of prosthetic feet are available, each with its own characteristics and functionalities. The selection of the foot component depends on factors such as the user's mobility needs, activity level, and terrain they typically encounter.

Overall, an above knee prosthesis is individually tailored to meet the specific needs and preferences of the user. The design and components of the prosthesis may vary based on advancements in prosthetic technology and the expertise of the prosthetist involved in the fitting process. Collaboration between the amputee and the prosthetist is essential to ensure a well-fitting and functional above knee prosthesis.
