Achilles tendon rupture - aftercareHeel cord tear; Calcaneal tendon rupture
The Achilles tendon connects your calf muscles to your heel bone. Together, they help you push your heel off the ground and go up on your toes. You use these muscles and your Achilles tendon when you walk, run, and jump.
If your Achilles tendon stretches too far, it can tear or rupture. If this happens, you may:
- Hear a snapping, cracking, or popping sound and feel a sharp pain in the back of your leg or ankle
- Have trouble moving your foot to walk or go up stairs
- Have difficulty standing on your toes
- Have bruising or swelling in your leg or foot
- Feel like the back of your ankle was hit with a bat
About Your Injury
Most likely your injury occurred when you:
- Suddenly pushed your foot off the ground, to go from walking to running, or to running uphill
- Tripped and fell, or had another accident
- Played a sport like tennis or basketball, with a lot of stopping and sharp turns
Most injuries can be diagnosed during a physical exam. You may need an MRI scan to see the location of your Achilles tendon tear. An MRI is a type of imaging test.
- A partial tear means at least some of the tendon is still OK.
- A full tear means your tendon is torn completely and the 2 sides are not attached to each other.
What to Expect
If you have a complete tear, you may need surgery to repair your tendon. Your doctor will discuss the pros and cons of surgery with you. Before surgery, you will wear a special boot that keeps you from moving your lower leg and foot.
For a partial tear:
- You may need surgery.
- Instead of surgery, you may need to wear a splint or boot for about 6 weeks. During this time, your tendon grows back together.
If you have a leg brace, splint, or boot, it will keep you from moving your foot. This will prevent further injury. You can walk once your doctor says it is OK to.
To relieve swelling:
- Put an ice pack on the area right after you injure it.
- Use pillows to raise your leg above the level of your heart when you sleep.
- Keep your foot elevated when you are sitting.
- Use a boot for walking or crutches to take weight off your ankle.
You can take ibuprofen (such as Advil or Motrin), naproxen (such as Aleve or Naprosyn), or acetaminophen (such as Tylenol) for pain.
- Talk with your health care provider if you have heart disease, liver disease, high blood pressure, kidney disease, or have had stomach ulcers or bleeding.
- Consider quitting smoking (smoking can affect healing after surgery).
- Not give aspirin to children under 19.
- Not take more pain killer than the dosage recommended on the bottle or by your provider.
Rehab and Activity
At some point as you recover, your provider will ask you to begin moving your heel. This may be as soon as 2 to 3 weeks or as long 6 weeks after your injury.
With the help of physical therapy, most people can return to normal activity in 4 to 6 months. In physical therapy, you will learn exercises to make your calf muscles stronger and your Achilles tendon more flexible.
When you stretch your calf muscles, do so slowly. Also, do not bounce or use too much force when you use your leg.
After you heal, you are at greater risk for injuring your Achilles tendon again. You will need to:
- Stay in good shape and stretch before any exercise
- Avoid high-heeled shoes
- Ask your provider if it is OK for you to play tennis, racquetball, basketball, and other sports where you stop and start
- Do a proper amount of warm up and stretching ahead of time
When to Call the Doctor
Call your provider if you have any of these symptoms:
- Swelling or pain in your leg, ankle, or foot becomes worse
- Purple color to leg or foot
- Swelling in your calf and foot
- Shortness of breath or difficulty breathing
Also call your provider if you have questions or concerns that cannot wait until your next visit.
