Abstract
An improved artificial ligament is tubular in overall configuration with flared ends, which have a graduated pore density to permit controlled hard and soft tissue ingrowth, and a central portion which prevents tissue ingrowth. The central section of the ligament is elongatable along its longitudinal axis to permit the needed elasticity in use.
