What Can You Do About Achilles Tendinitis

Overview
A tendon is a tough yet flexible band of fibrous tissue. The tendon is the structure in your body that connects your muscles to the bones. The skeletal muscles in your body are responsible for moving your bones, thus enabling you to walk, jump, lift, and move in many ways. When a muscle contracts it pulls on a bone to cause movements. The structure that transmits the force of the muscle contraction to the bone is called a tendon. Tendons come in many shapes and sizes. Some are very small, like the ones that cause movements of your fingers, and some are much larger, such as your Achilles tendon in your heel. When functioning normally, these tendons glide easily and smoothly as the muscle contracts. Sometimes the tendons become inflamed for a variety of reasons, and the action of pulling the muscle becomes irritating. If the normal smooth gliding motion of your tendon is impaired, the tendon will become inflamed and movement will become painful. This is called tendonitis, and literally means inflammation of the tendon.

Causes
There are a number of ways a person can develop Achilles tendinitis. Some causes are easier to avoid than others, but being aware of them can aid earlier diagnosis and help prevent serious injury. Causes of Achilles tendinitis include, using incorrect or worn out shoes when running or exercising. Not warming up properly before exercise. Increasing intensity of exercise too quickly (e.g. running speed or distance covered). Prematurely introducing hill running or stair climbing to exercise routine. Running on hard or uneven surfaces. Calf muscle is injured or has little flexibility (this puts a lot of strain on the Achilles tendon). Sudden intense physical activity such as sprinting for the finish line. Achilles tendinitis can also be caused by differences in foot, leg or ankle anatomy. For example, some people can have flatness in their foot where there would normally be an arch; this puts more strain on the tendon. The FDA has asked that a boxed warning be added to the prescribing information for fluoroquinolone antibiotics. Patients taking these drugs may experience an increased risk of tendinitis and tendon rupture. Fluoroquinolones include Cipro (ciprofloxacin), Factive (gemifloxacin), Levaquin (levofloxacin), Avelox (moxifloxacin), Noroxin (norfloxacin), Floxin (ofloxacin) and Proquin (ciprofloxacin hydrochloride). It is important to remember that the risk for injury is not necessarily gone when the drug is stopped. Cases have been reported in which tendon problems occurred up to several months after the drug was discontinued.

Symptoms
Symptoms of acute achilles tendonitis will be a gradual onset of achilles pain at the back of the ankle, just above the heel bone. This may develop over a period of days. The achilles tendon may be painful and stiff at the start of exercise and first thing in the morning. As the tendon warms up the pain will go often for it to return later in the day or towards the end of a prolonged training session. The tendon will be very tender on palpation or pressing in on the achilles tendon or squeezing it from the sides. Chronic achilles tendonitis may follow on from acute achilles tendonitis if it goes untreated or is not allowed sufficient rest. Chronic achilles tendonitis is a difficult condition to treat, particularly in older athletes who appear to suffer more often.

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
There are many nonsurgical ways for treating both forms of tendinitis like resting, putting ice on the area and exercises. Healing of the Achilles tendon can be a slow process, because the area has poor blood supply. If the condition becomes chronic and symptoms do not improve within 6 months, surgery might be needed. Surgical treatment may be suggested if pain has not improved after six months of nonsurgical care.



Surgical Treatment
Chronic Achilles tendon tears can be more complicated to repair. A tendon that has torn and retracted (pulled back) into the leg will scar in the shortened position over time. Restoring normal tendon length is usually not an issue when surgery is performed within a few weeks of the injury. However, when there has been a delay of months or longer, the treatment can be more complicated. Several procedures can be used to add length to a chronic Achilles tear. A turndown procedure uses tissue folded down from the top of the calf to add length to the Achilles tendon. Tendon transfers from other tendons of the ankle can also be performed to help restore function of the Achilles. The results of surgery in a chronic situation are seldom as good as an acute repair. However, in some patients, these procedures can help restore function of a chronically damaged Achilles.

Prevention
A 2014 study looked at the effect of using foot orthotics on the Achilles tendon. The researchers found that running with foot orthotics resulted in a significant decrease in Achilles tendon load compared to running without orthotics. This study indicates that foot orthoses may act to reduce the incidence of chronic Achilles tendon pathologies in runners by reducing stress on the Achilles tendon1. Orthotics seem to reduce load on the Achilles tendon by reducing excessive pronation,
