Abstract
A modular prosthetic ligament is disclosed for replacing a natural ligament which joins and allows articulation between adjacent ends of two bones. The prosthetic ligament includes a first anchor element, for disposition in the adjacent end of one of the bones, a second anchor element for disposition in the adjacent end of the other bone, and a cable assembly for interconnecting the first and second anchor elements. The cable assembly includes a hollow housing, one side of which is detachably joinable to the first anchor element, and the other side of which includes a slot through which one end of a cable is threaded to extend into the housing hollow. A ball or cylinder is disposed in the hollow of the housing and is coupled to the cable so that when the cable moves in the slot, the ball rolls or moves in the hollow of the housing. The other end of the cable is coupled to the second anchor element.
