Below Knee Prosthetic Leg – Transtibial Amputation



Transtibial amputation, also known as, below knee amputation, is one of the most frequently performed limb amputation surgeries. A transtibial amputation is one that is below the knee joint and above the ankle, a below knee prosthesis is used to replace this part of the missing leg.

Elements of a Below Knee Prosthesic Leg

A below knee prosthesic leg is comprised of a suspension sleeve, socket, pylon and prosthetic foot, with the socket being the most important part of the prosthesis. Different factors are used to determine what type of socket, suspension and prosthetic foot will be best for your individual functional level.

Below Knee Prosthetic Leg – Fitting Process

Working as a team, we will make a below knee prosthetic leg for you based off information we gather during the evaluation phase. The first step in the process of making the prosthesis is to take an impression of your residual limb. At POSI, this impression is captured by hand casting as this method provides a very precise fit that will maximize comfort.
