Abstract
A prosthetic joint in an embodiment has two load-bearing surfaces that are slidingly disposed relative to each other and define a region of frictional contact. The joint is thermally managed as heat is removed from the region during joint use by thermal conduction so that the surfaces are maintained approximately at or below specified temperatures. In other embodiments, heat flows preferentially through one member which includes one of the surfaces. Use of high thermal conductivity materials in conjunction with various joint designs affording thermally managed devices are provided in numerous embodiments.
