Achilles Tendonitis

Overview
The Achilles tendon is the largest tendon in the body. Tendons are long, tough cords of tissue that connect muscle to bone. The Achilles tendon is located in the back of the foot and connects your heel bone to your calf muscle. It helps you to walk, run and jump. The Achilles tendon is able to endure stress, but sometimes injury can occur to the tendon when overly stressed. Overuse of the Achilles tendon may cause the tendon to swell, become irritated, inflamed and cause pain. This is Achilles tendinitis. It is a common sports injury related to running, but can happen to anyone who puts a lot of stress on their feet (e.g.: basketball players and dancers). If you do not get treatment for Achilles tendinitis, the problem can become chronic and make it difficult for you to walk.

Causes
In some cases, Achilles Tendinitis can be caused by physical activity without a proper warm up or trauma, such as falling, to cause an overstressing of the muscle and tendon. Other causes include repetitive overuse syndrome, such as a job that required frequent heel lifting. Biomechanical causes such as pronation (or fallen arches) will cause the heel (calcaneus) to lean slightly, putting the undue stress on the Achilles tendon and the calf muscles. Most pain can be felt at the back of the heel or the point at which the calf muscle becomes a tendon three quarters of the distance down from the knee. Discomfort can be felt especially when jumping or when lifting the heel off the ground. Swelling and redness can often be seen at the back of the heel and touching the area would cause a tender sensation. In extreme cases, the tendon can become torn or rupture entirely which would cause bruising or an inability to put pressure on the foot.

Symptoms
There are several types of Achilles tendinitis symptoms, but all of them are closely related. People who suffer from Achilles tendon pain typically have swelling in the Achilles tendon, and that pain can be chronic as the microscopic tears in the area become more prevalent over time. The most intense pain is typically located just a few centimeters above the area where the tendon meets the heel. This area is called the watershed zone, and the amount of blood moving through it is what gives it the highest potential for injury, especially for athletes. Most of the Achilles tendinitis symptoms in people with the condition will happen immediately after they have been inactive for a fairly significant amount of time. That means that the most pain will generally be felt after sitting or lying down for an extended period, or right after waking up in the morning and getting moving. If you aren?t positive that you are suffering specifically from Achilles tendinitis symptoms, consult a doctor to make sure.

Diagnosis
A doctor or professional therapist will confirm a diagnosis, identify and correct possible causes, apply treatment and prescribe eccentric rehabilitation exercises. An MRI or Ultrasound scan can determine the extent of the injury and indicate a precise diagnosis. Gait analysis along with a physical assessment will identify any possible biomechanical factors such as over pronation which may have contributed to the achilles tendonitis and training methods will be considered. Biomechanical problems can be corrected with the use of orthotic inserts and selection of correct footwear.

Nonsurgical Treatment
Initial treatment of mild Achilles tendinitis involves rest, stretching exercises, and non-prescriptive medications to relieve pain and reduce inflammation. These medications include nonsteroidal anti-inflammatory drugs (NSAID) such as ibuprofen or naproxen. Relief of pain and swelling may be achieved with the application of ice for15 minutes at a time. Sleeping with the affected foot propped up on a pillow may also relieve swelling. Adequate time must be given to rest and recovery, meaning months or weeks, to prevent re-injury of the Achilles tendon. Most people make a full recovery and are able to return to their regular sports and exercise programs.


Surgical Treatment
Surgery usually isn't needed to treat Achilles tendinopathy. But in rare cases, someone might consider surgery when rubbing between the tendon and the tissue covering the tendon (tendon sheath) causes the sheath to become thick and fibrous. Surgery can be done to remove the fibrous tissue and repair any small tendon tears. This may also help prevent an Achilles tendon rupture.

Prevention
Warm up slowly by running at least one minute per mile slower than your usual pace for the first mile. Running backwards during your first mile is also a very effective way to warm up the Achilles, because doing so produces a gentle eccentric load that acts to strengthen the tendon. Runners should also avoid making sudden changes in mileage, and they should be particularly careful when wearing racing flats, as these shoes produce very rapid rates of pronation that increase the risk of Achilles tendon injury. If you have a tendency to be stiff, spend extra time stretching. If you?re overly flexible, perform eccentric load exercises preventively. Lastly, it is always important to control biomechanical alignment issues, either with proper running shoes and if necessary, stock or custom orthotics.
