A synthetic ligament made of a plurality of polymer filaments comprising two intra-osseous portions (1), within which polymer filaments are oriented only longitudinally and are woven together longitudinally and knotlessly to form a dense weave, and one intra-articular portion (2), located between the two intra-osseous portions (1), which comprises loose filaments and is untwisted around its axis. A method of producing a synthetic ligament in which the step of weaving of the polymer filaments within the intra-osseous portions (1) is carried out by means of longitudinal and knotless weaving to obtain a dense weave, with polymer filaments within the intra-articular portion (2) of a ligament remaining loose. A use of a synthetic ligament as a medical implant for the reconstruction of ligaments and tendons, notably knee ligaments.
A synthetic ligament made of a plurality of polymer filaments comprising two intra-osseous portions, within which the polymer filaments are woven together, and one intra-articular portion, located between the two intra-osseous portions, within which the polymer filaments constitute loose filaments, wherein polymer filaments within the two intra-osseous portions are oriented only longitudinally and are woven together longitudinally and knotlessly to form a dense weave whereas the one intra-articular portion comprising loose filaments is untwisted around its axis.
A method of producing a synthetic ligament made of a plurality of polymer filaments comprising two intra-osseous portions, within which the polymer filaments are woven together, and one intra-articular portion, located between the two intra-osseous portions, within which the polymer filaments constitute loose filaments, wherein said method comprises the steps of preparation of polymer filaments, weaving of polymer filaments, and cleaning and sterilising a ligament, wherein the step of weaving of polymer filaments within the intra-osseous portions is carried out by means of longitudinal and knotless weaving until a dense weave is obtained, with polymer filaments within the intra-articular portion of a ligament remaining loose, until a tubular structure of a ligament is obtained, wherein the intra-articular portion comprising loose polymer filaments is left untwisted around its axis.
