Abstract
The ligament prosthesis is formed of concentric tubes of filaments threads. In addition, a layer of elastomer is disposed over at least the outermost tube to act as an impermeable layer to the passage of abraded material from within the tubes into the lining. The thickness of the elastomer layer is at most 0.1 millimeter. The elastomer may also be provided on and about the threads of the inner tubes to reduce a migration of abraded particles therein.
