What Is The Leading Cause Of Achilles Tendonitis

Overview
Achilles tendonitis is a condition of irritation and inflammation of the large tendon in the back of the ankle. Achilles tendonitis is a common injury that tends to occur in recreational athletes. Overuse of the Achilles tendon can cause inflammation that can lead to pain and swelling. Achilles tendonitis is differentiated from another common Achilles tendon condition called Achilles tendinosis. Patients with Achilles tendinosis have chronic Achilles swelling and pain as a result of degenerative, microscopic tears within the tendon.

Causes
Poorly conditioned athletes are at the highest risk for developing Achilles tendonitis, also sometimes called Achilles tendinitis. Participating in activities that involve sudden stops and starts and repetitive jumping (e.g., basketball, tennis, dancing) increases the risk for the condition. It often develops following sudden changes in activity level, training on poor surfaces, or wearing inappropriate footwear. Achilles tendonitis may be caused by a single incident of overstressing the tendon, or it may result from a series of stresses that produce small tears over time (overuse). Patients who develop arthritis in the heel have an increased risk for developing Achilles tendonitis. This occurs more often in people who middle aged and older. The condition also may develop in people who exercise infrequently and in those who are just beginning an exercise program, because inactive muscles and tendons have little flexibility because of inactivity. It is important for people who are just starting to exercise to stretch properly, start slowly, and increase gradually. In some cases, a congenital (i.e., present at birth) condition causes Achilles tendonitis. Typically, this is due to abnormal rotation of the foot and leg (pronation), which causes the arch of the foot to flatten and the leg to twist more than normal.

Symptoms
Achilles tendonitis and tendinopathy present as pain in the Achilles tendon, usually several centimeters above where it inserts on the heel. In some patients, pain and tendon damage are primarily at the insertion to the heel bone. There may be swelling and/or thickening of the tendon. Bending at the ankle, walking, jumping, and running are often painful with this condition.

Diagnosis
A podiatrist can usually make the diagnosis by clinical history and physical examination alone. Pain with touching or stretching the tendon is typical. There may also be a visible swelling to the tendon. The patient frequently has difficulty plantarflexing (pushing down the ball of the foot and toes, like one would press on a gas pedal), particularly against resistance. In most cases X-rays don't show much, as they tend to show bone more than soft tissues. But X-rays may show associated degeneration of the heel bone that is common with Achilles Tendon problems. For example, heel spurs, calcification within the tendon, avulsion fractures, periostitis (a bruising of the outer covering of the bone) may all be seen on X-ray. In cases where we are uncertain as to the extent of the damage to the tendon, though, an MRI scan may be necessary, which images the soft tissues better than X-rays. When the tendon is simply inflamed and not severely damaged, the problem may or may not be visible on MRI. It depends upon the severity of the condition.

Nonsurgical Treatment
Treatment approaches for Achilles tendonitis or tendonosis are selected on the basis of how long the injury has been present and the degree of damage to the tendon. In the early stage, when there is sudden (acute) inflammation, one or more of the following options may be recommended. Immobilization. Immobilization may involve the use of a cast or removable walking boot to reduce forces through the Achilles tendon and promote healing. Ice. To reduce swelling due to inflammation, apply a bag of ice over a thin towel to the affected area for 20 minutes of each waking hour. Do not put ice directly against the skin. Oral medications. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, may be helpful in reducing the pain and inflammation in the early stage of the condition. Orthotics. For those with over-pronation or gait abnormalities, custom orthotic devices may be prescribed. Night splints. Night splints help to maintain a stretch in the Achilles tendon during sleep. Physical therapy. Physical therapy may include strengthening exercises, soft-tissue massage/mobilization, gait and running re-education, stretching, and ultrasound therapy.


Surgical Treatment
Most people will improve with simple measures or physiotherapy. A small number continue to have major problems which interfere with their lifestyle. In this situation an operation may be considered. If an operation is being considered, the surgeon will interview you and examine you again and may want you to have further treatment before making a decision about an operation. Before undergoing Achilles tendonitis surgery, London based patients, and those who can travel, will be advised to undergo a scan, which will reveal whether there is a problem in the tendon which can be corrected by surgery. Patients will also have the opportunity to ask any questions and raise any concerns that they may have, so that they can proceed with the treatment with peace of mind.

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.
