socket design

Photo demonstrates the still common transtibial (below knee) socket design with a very narrow pressure area between the back of the knee and just under the knee cap. This provides a firm lock to hold the stump off the bottom of the socket by overloading the soft tissues in these areas. The area in the back of the knee contains several major blood vessels and nerve pathways that we do not want to overload.

Socket Design The socket is the part of the prosthetic limb that is in contact with your body. This part of the leg is probably the most important, because its where your body weight is transferred to the prosthetic limb. The reason we spend so much time on this part is to make sure the weight is distributed safely and comfortably to protect your stump and joints.
