Abstract
A prosthetic ligament and its method of manufacture is provided by which the prosthetic ligament is comprised of a plurality of strands aligned in a parallel lengthwise relationship to form a bundle, with the strands being interwoven at their respective ends while the middle portion of the strands remain unattached to adjacent strands. A predetermined torsion is applied to each strand prior to forming the bundle to create natural coiling in either a clockwise or counter-clockwise orientation. The prosthetic ligament may be used for a posterior or anterior cruciate ligament of the knee joint.
