Your Achilles tendon helps you point your foot downward, rise on your toes and push off your foot as you walk. You rely on it virtually every time you move your foot.

Rupture usually occurs in the section of the tendon located within 2.5 inches (6 centimeters) of the point where it attaches to the heel bone. This section may be predisposed to rupture because it gets less blood flow, which may impair its ability to heal.

Ruptures often are caused by a sudden increase in the amount of stress on your Achilles tendon. Common examples include:

  • Increasing the intensity of sports participation
  • Falling from a height
  • Stepping into a hole
