Abstract
A multilayered or tubular, woven artificial ligament contains distinct regions, each of which has physical properties suited to the function to be served. An intra-articular region is characterized by a woven structure, a high elongation under load and a degree of elasticity, similar to that of natural ligaments. A region which resides in a tunnel bored into a bone is characterized by a low elongation under load and a degree of porosity which promotes boney attachment of the ligament to the host bone. The artificial ligaments are woven from low elongation yarns, and the properties of the different regions of the ligaments are achieved through careful control of the weaving conditions and post-weaving, heat-setting treatments.
