Achilles Tendon Rupture

Medically reviewed by Last updated on Jan 5, 2023.

What is an Achilles tendon rupture?

An Achilles tendon rupture happens when your Achilles tendon tears, or separates from your heel bone. The Achilles tendon connects your calf muscle to your heel bone. It allows you to point your foot down and to rise on your toes. An Achilles tendon rupture may be caused by a sports injury or a fall.

Heel, toes, ankle

What increases my risk for an Achilles tendon rupture?

  • A previous Achilles tendon tear, rupture, or tendinitis
  • A sudden increase in the intensity of an activity
  • Tight calf muscles
  • Arthritis, gout, or lupus
  • Age older than 30
  • Medicines such as steroids or antibiotics

What are the signs and symptoms of an Achilles tendon rupture?

  • A sudden pop, snap, or crack at the back of your leg
  • Severe pain in your leg or ankle, especially when your foot is bent down
  • Swelling, stiffness, or weakness in your leg or ankle
  • A bruise on the back of your ankle
  • Trouble moving or putting weight on your leg

How is an Achilles tendon rupture diagnosed?

Tell your healthcare provider what you were doing when your symptoms started. He or she will bend your knee and squeeze the lower part of your calf. If your foot or ankle does not move, the tendon is torn. You may need an x-ray, ultrasound, or MRI to check for a tear or damage to your Achilles tendon. Do not enter the MRI room with anything metal. Metal can cause serious injury. Tell the healthcare provider if you have any metal in or on your body.

How is an Achilles tendon rupture treated?

  • Medicine can help decrease pain and swelling.
  • A cast, brace, or splint may be used to keep your foot from moving. This will help your tendon heal. Your healthcare provider may change your cast and your foot position several times while the tendon heals. After several weeks of a cast or splint, you may need heel lifts placed in your shoes. This will decrease stress on your Achilles tendon.
  • Physical therapy may be needed. A physical therapist teaches you exercises to help improve movement and strength, and decrease pain. You may not start physical therapy for a few weeks or until your cast is removed.
  • Surgery may be needed if other treatments do not work. The edges of your tendon may need to be stitched back together. You may need a graft to patch the tear. A graft is a piece of another tendon or artificial material.
