1. An artificial tendon for forming a strong musculotendinous interface with a skeletal muscle, comprising:

  • a cord of high break strength forming the body of the artificial tendon;

    tissue ingrowth means to promote musculotendinous attachment, having an interfacing surface with a relatively large surface area bonded to one end of said cord, said tissue ingrowth means being wrappable about the end of a skeletal muscle or tendon to form a large interface; and

    a tissue ingrowth impervious backing bonded to the back non-interfacing surface of said tissue ingrowth means;

    whereby a strong interface is provided for tissue ingrowth from the skeletal muscle to the large surface area of said tissue ingrowth means while said impervious backing prevents tissue ingrowth on the non-interfacing surface and prevents the artificial tendon from being thereby immobilized, so that the artificial tendon remains securely attached to the skeletal muscle while being slidable in the body with the contraction or extension of the skeletal muscle.
