Achilles Tendon Disorders

The Achilles tendon, which connects the calf muscles to the heel bone, is the largest tendon in the body. It is the muscle that lets you rise up on your toes and push off when you walk or run.

Injuries to this tendon are generally caused by overuse and tend to be common in athletes. Injuries include:

  • Achilles tendonitis: inflammation of the tendon, generally from chronic overuse
  • Achilles tendon rupture: a partial or complete tear of the tendon 
Normal Achilles tendon

Symptoms of Achilles tendonitis include:

  • Pain in the back of the heel. Pain may be mild or severe, and swelling may occur
  • Tenderness in the Achilles tendon area
  • Stiffness that goes away as the tendon warms up with use
  • Decreased strength and movement
  • The tendon may become enlarged

Symptoms of Achilles tear or rupture include:

  • A sudden, sharp pain that feels like a direct hit to the Achilles tendon. There may be a pop when the rupture occurs. This may be followed by swelling and bruising.
  • Heel pain (may be severe)
  • Not being able raise up on the toes with the hurt leg

Treatment options

Treatments for Achilles tendonitis include:

  • Resting the leg and foot by avoiding any intense activity for 6 to 12 weeks 
  • Switching to other activities, such as swimming instead of running
  • Wearing well-cushioned shoes, heel pads, or other orthotics to help relieve pain
  • Reducing pain with over-the-counter pain relievers or ice
  • Stretching exercises or physical therapy

Treatments for more serious injuries such as Achilles tendon tears or ruptures can include long term immobilization or surgery. During immobilization, the injured tendon may reattach and heal. However, there is a greater risk of re-rupture than with surgery.

Surgery allows the orthopedic surgeon to repair the ruptured tendon. The surgeon makes a single incision in the back of the leg and reattaches the ends of the tendon.

After surgery, you'll be wearing a cast or walking boot for six to 12 weeks as you heal. Your recovery will include rehabilitation such as exercises and physical therapy. Your surgeon will work closely with you to determine the type and length of rehabilition that's best for you.
