Answer:

Structural and functional differences between a tendon and a ligament - such as elastin content, fiber organization, shape and size or compression resistance - mean that when one tendon is badly damaged, it can only be replaced by another tendon.

Explanation:

Ligaments and tendons are important structures of the locomotor system, having some characteristics in common, but with different structures and functions.

1. Ligaments are broad and short bands of connective tissue, whose function is to keep two bones together and stable.

Compared to tendons, the ligaments are:

  • Stiffer.
  • Resistant but with little elasticity.
  • They are less resistant to compression.
  • With less organized collagen fibers.

2. Tendons are the structures that allow the union between a muscle and a bone. According to their function, as an extension of the muscle, the tendons have:

  • Shape of elongated and narrow bands.
  • High resistance and elasticity.
  • Fibers organized longitudinally.
  • High compress resistance, with the ability to stretch and recover its original shape and size.

When it's required to replace a badly damaged tendon, it should be done with a similar tissue, that is, another tendon.  

The ligaments don't have an adequate structure, elasticity, strength or size to be used as a replacement for a damaged tendon.
