In the case of transtibial amputations, the ideal option is to use an adjustable prosthesis. Below, knee prosthesis also consists of the same components as in above-knee amputation. But in these prostheses, there is no need for moving or adjustable knee joints. The movement on the knee joint is free, which makes it easier to walk with these devices without any need for the knee joint.
In transtibial amputations, the prosthesis contains the following significant features:
1. A soft inner liner which helps to give the stump a more comfortable receptacle
2. A suction-socket valve which helps in reducing the motion between socket and stump
3. There should be total contact between the prosthesis and the body to improve body weight support.
4. The prosthesis should also contain air cushioning for minimizing the displacement of the stump and improving the comfort of the socket.
5. Following the liner, there should be a suction socket shell in a relative sitting position.
6. The prosthesis should also contain a removable liner for maximizing the facilitation of minor adjustments of the socket.
