A synthetic prosthesis for replacement or repair of ligaments or tendons

The inventive article is a ligament or tendon prosthesis (10) having multiple longitudinally parallel strands (20) of microporous expanded polytetrafluoroethylene, the individual strands having an average porosity greater than 30% in the areas requiring tissue ingrowth. Additionally, strand dimensions and microstructure are selected so that tissue can penetrate throughout. The prosthesis is formed from multiple loops of a single continuous filament. Densified eyelets (24) (26) are formed in the loop for mounting to bone. The strands (20) are twisted 180° or arranged in a loose braid about the prosthesis axis for improved load distribution during bending of the prosthesis.
