Abstract
A prosthetic liner for use with a prosthetic assembly that acts as the interface between the residual limb of an amputee and the socket assembly. The prosthetic liner comprises an outer textile with variable stretch characteristics due to the knit construction and stitching and an interior gel layer. The distal region of the liner textile has less stretch than does the intermediate region or proximal region and is stitched together to form a unitary liner. The liner advantageously minimizes a condition referred to as 'pistoning' wherein the distal most portion of the residual limb ascends and descends in the lower portion of the socket creating an unhealthy condition for the residual limb.
