Thank You for Watching!!
Knee Ligaments

A completely finished artificial leg that has been fitted to the amputee with the intent to provide efficient and continuous serv­ice. The prosthesis must embody all accepted principles of prosthetic fitting that will best compensate for the existing disability with due regard to the economic, vocational and psychiatric facets of the wearer.

Permanent and Temporary

The bones of the leg and foot form part of the appendicular skeleton that supports many muscles of the lower limbs. These muscles work together to produce movements such as standing, walking, running, and jumping. At the same time, the bones and joints of the leg and foot must be strong enough to support the body’s weight while remaining flexible enough for movement and balance.

The femur is the largest, heaviest, and strongest bone in the human body It connects to the pelvis to form the hip(ball-and-socket) joint and then extends down to meet the tibia at the knee joint.

The lower-leg bones, the tibia and fibula, also help to form the ankle joint. The tibia sits on top of the talus (an ankle bone), which fits into the calcaneus (heel bone).

The Ankle And The Foot
The ankle joint is created at the junction of the tibia, fibula, and the talus( the ankle bone). There are three separate joints formed by these three bones, all of which are secured by a protective structure known as the synovial capsule

Types of Artificial Leg

Permanent Prosthesis :

An appliance worn by a recent amputee pending the procurement of a permanent artificial leg or the contradiction of a prosthesis. Due to the inherent purpose of this appliance, perfection in fit, alignment and function is usually not sought. The prime purpose of the device is to obtain early attempts at ambulation at the possible expense of prosthetic perfection.

Temporary Prosthesis :
Foot , Above and Below the Knee

This type of prosthesis is made with a thigh, knee, shin, foot, and ankle. It is made of a metal tube with a socket on top to connect to the stump. The knee part of the prosthesis is bendable for walking, sitting, and kneeling.

Above-the-knee prosthesis:
Below-the-knee prosthesis:
This has a shin made of a metal tube with a socket on top to connect to your stump. It connects to the artificial foot and ankle at the bottom.

We began our research with the anatomy and physiology of the leg to become able to determine what types of materials we need for the artificial leg.

Also we found deep information about the types of artificial leg to choose one of them to design it for our project.
