Abstract
A prosthetic ligament device comprising an elastic element securable to the underlying bone structure by means of a quick release bayonet-type fitting which permits rotational movement during engagement at one end and a length adjusting means at the other end thereof. The elastic element comprises a plurality of parallel, longitudinal, polyester cords which form the warp, interwoven with a plurality of transverse soft silicone or polyurethane tubes which form the weft. Upon extension the soft tubes compress so as to permit a relatively large elongation of the elastic element at low stress, but upon continued extension the elastic element becomes progressively stiffer, simulating a natural ligament.
