The exact cause is not known. It is thought to be caused by:

  • Putting sudden stress on the muscle, such as from landing a jump, lunging, or sprinting
  • Stretching the muscle too far
  • Falling or tripping

Risk Factors

This problem is more common in people who:

  • Are 30 to 40 years of age, often males who play sports
  • Are over 60 years old, often women when climbing stairs
  • Play basketball or racket sports

Some other things that may raise the risk are:

  • Achilles tendinopathy
  • Recent changes in activity
  • Poor footwear
  • Alignment problems
  • Calf muscles that are weak or are not flexible
  • Prior rupture
  • Obesity
  • Certain medicines, such as fluoroquinolones


Problems may be:

  • Sudden pain at the back of the heel
  • A popping or snapping noise
  • Swelling between the heel and calf
  • Problems walking
  • Problems pushing off from the ball of the foot


You will be asked about your symptoms and health history. An exam will be done. It will focus on the foot. This may be enough to suspect a rupture.

Images may be taken to confirm the rupture. This can be done with:


Treatment depends on the amount of damage and the person's health. Options are:

Supportive Care

A minor rupture in someone who is less active or not well enough for surgery may be treated with:

  • Rest, ice, compression, and elevation
  • Medicines to ease pain and swelling
  • Crutches or a walker to keep weight off of the leg
  • Physical therapy to strengthen the muscles


Surgery may be done to sew the tendon back together. This lowers the risk of it rupturing again.


There are no known guidelines to prevent an Achilles tendon rupture.
