Different prosthetic constructions are utilised to fit transtibial amputations, often known as below-knee amputations. Transtibial short prostheses are distinguished from conventional thigh sleeve prostheses and side joint bars, which are no longer useful due to sophisticated residual limb encasement procedures. Patients were not allowed to use them if they had short residual limbs, knee fractures, or malfunctions (such as paralysis or incorrect alignment). A combination with a tuberosity seat may be recommended in some circumstances to provide relief.

Short-prostheses, including joint bar atrophy and constriction, limited mobility in the knee joint, losing full contact, etc. A crucial requirement for proper fitting is the accurate encasing of the residual limb, which is often provided with a plaster model-based contact socket that covers the condyles. For biomechanical alignment, the same applies.

There are high demands placed on the fit and functionality of the transtibial socket because there is only a small quantity of soft tissue, which the prosthetist can manage using a variety of application techniques and materials.
