Abstract
The crucial ligament replacement is formed with two cords to define the anterior crucial ligament and posterior crucial ligament. The cords interpenetrate each other within sections of relatively great flexibility and relatively large longitudinal stretchability so that mutual movement between the two cords at the crossing point is reduced to a minimum where an attrition are greatly reduced at the crossing point.
