Overview
The Achilles tendon attaches the calf muscle to the heel bone. Achilles tendonitis is a repetitive strain (overuse) injury involving lower leg muscles and tendons at the point where they attach to the bone, resulting in pain at the back of the ankle. Chronic overuse can lead to small tears within the tendon causing long-term weakening, making the tendon susceptible to rupture, which could result in a need for surgery.

Causes
Achilles tendonitis is an overuse injury. Too much too soon is the common cause of overuse injuries, however other factors can contribute to developing the condition. An increase in activity, either distance, speed or a sudden change to running up hills. As a rule of thumb distance runners should increase their mileage by no more than 10% per week. A change of footwear or training surface for example suddenly running on soft sand can cause the heel to drop lower than normal making the tendon stretch further than it is used to. Weak calf muscles can tighten or go into partial spasm which again increases the strain on the achilles tendon by shortening the muscle. Running up hills - the achilles tendon has to stretch more than normal on every stride. This is fine for a while but will mean the tendon will fatigue sooner than normal. Overpronation or feet which roll in when running can place an increased strain on the achilles tendon. As the foot rolls in (flattens) the lower leg also rotates inwards which places twisting stresses on the tendon. Wearing high heels constantly shortens the tendon and calf muscles. When exercising in flat running shoes, the tendon is stretched beyond its normal range which places an abnormal strain on the tendon.

Symptoms
The onset of the symptoms of Achilles tendonitis tend to be gradual, with symptoms usually developing over a period of several days, or even weeks. Symptoms may include, Pain, this may be mild at first and may only be noticeable after exercise. Over time the pain may become constant and severe. Stiffness, this is usually relieved by activity. Sluggishness in the leg. Tenderness, particularly in the morning and most commonly felt just above where the tendon attaches to the heel bone. Swelling.

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
The first thing to do is to cut back your training. If you are working out twice a day, change to once a day and take one or two days off per week. If you are working out every day cut back to every other day and decrease your mileage. Training modification is essential to treatment of this potentially long lasting problem. You should also cut back on hill work and speed work. Post running ice may also help. Be sure to avoid excessive stretching. The first phase of healing should be accompanied by relative rest, which doesn't necessarily mean stopping running, but as I am emphasizing, a cut back in training. If this does not help quickly, consider the use of a 1/4 inch heel lift can also help. Do not start worrying if you will become dependent on this, concentrate on getting rid of the pain. Don't walk barefoot around your house, avoid excessively flat shoes, such as "sneakers", tennis shoes, cross trainers, etc. In office treatment would initially consist of the use of the physical therapy modalities of electrical stimulation, (HVGS, high voltage galvanic stimulation), and ultrasound. Your sports medicine physician should also carefully check your shoes. A heel lift can also be used and control of excessive pronation by taping can also be incorporated into a program of achilles tendonitis rehabilitation therapy. Orthotics with a small heel lift are often helpful.



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
Although Achilles tendinitis cannot be completely prevented, the risk of developing it can be lowered. Being aware of the possible causes does help, but the risk can be greatly reduced by taking the following precautions. Getting a variety of exercise - alternating between high-impact exercises (e.g. running) and low-impact exercise (e.g. swimming) can help, as it means there are days when the Achilles tendon is under less tension. Limit certain exercises - doing too much hill running, for example, can put excessive strain on the Achilles tendon. Wearing the correct shoes and replacing them when worn - making sure they support the arch and protect the heel will create less tension in the tendon. Using arch supports inside the shoe, if the shoe is in good condition but doesn't provide the required arch support this is a cheaper (and possibly more effective) alternative to replacing the shoe completely. Stretching, doing this before and after exercising helps to keep the Achilles tendon flexible, which means less chance of tendinitis developing. There is no harm in stretching every day (even on days of rest), as this will only further improve flexibility. Gradually increasing the intensity of a workout - Achilles tendinitis can occur when the tendon is suddenly put under too much strain, warming up and increasing the level of activity gradually gives your muscles time to loosen up and puts less pressure on the tendon.
