Overview
Achilles tendinitis (or Achilles tendonitis) is a strain of the Achilles tendon, which connects the calf muscles to the heel bone. Pain can be moderate or severe, but the condition is not usually serious. Of course, if you are suffering the leg and heel pain it brings, it certainly feels serious enough.

Causes
Tight or tired calf muscles, which transfer too much of the force associated with running onto the Achilles tendon. Not stretching the calves properly or a rapid increase in intensity and frequency of sport training can make calf muscles fatigued. Activities which place a lot of stress on the achilles tendon, such as hill running and sprint training, can also cause Achilles Tendinitis. Runners who overpronate (roll too far inward on their feet during impact) are most susceptible to Achilles Tendinitis. Runners with flat feet are susceptible to Achilles Tendinitis because flat feet cause a 'wringing out' effect on the achilles tendon during running. High arched feet usually absorb less shock from the impact of running so that shock is transferred to the Achilles tendon. Use of inappropriate footwear when playing sport or running e.g., sandals, can also put an extra load on the Achilles tendon. Shoes are now available that have been designed for individual sports and provide cushioning to absorb the shock of impact and support for the foot during forceful movements. Training on hard surfaces e.g., concrete, also increases the risk of Achilles Tendinitis. Landing heavily or continuously on a hard surface can send a shock through the body which is partly absorbed by the Achilles tendon. A soft surface like grass turf helps to lessen the shock of the impact by absorbing some of the force of the feet landing heavily on the ground after a jump or during a running motion.

Symptoms
Symptoms of Achilles tendinitis and tendinosis include recurring localized heel pain, sometimes severe, along the achilles tendon during or after exercise. Pain often begins after exercise and gradually worsens. Morning tenderness or stiffness about an inch and a half above the point where the Achilles tendon is attached to the heel bone. Sluggishness in your leg. Mild to severe swelling. Stiffness that generally diminishes as the tendon warms up with use.

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
Wear shoes with a low half-inch to one-inch heel that are somewhat flexible through the ball of the foot. Avoid flat footwear such as slippers or sandals and stiff shoes. Add a heel lift in your shoe. You may also use arch support inserts or orthotic insoles. Heel lifts and orthotics can be purchased at many of our pharmacies and Podiatry departments. Avoid standing or walking barefoot. Perform calf-stretching exercises for 30 to 60 seconds on each leg at least 2 times a day. Stand an arm?s length away from a wall, facing the wall. Lean into the wall, stepping forward with one leg, leaving the other stretched behind you. The leg behind you is the one being stretched. Keep this leg straight (locked) and the toes pointed straight at the wall. Stretch forward until you feel tightness in the calf of your back leg. Hold this position without bouncing for 30 to 60 seconds. Repeat for the opposite leg. Do stair exercises every day. Stand facing the stairs with the ball of your foot on a stair and your heel hanging off. Balance on one foot at a time while holding onto the rail. Slowly lower your heel as low as it will drop down and then slowly raise it up as high as you can lift it. Repeat this exercise slowly several times on each foot. Perform this exercise every other day, gradually increasing the number of repetitions over time as tolerated. If you are overweight, talk to your personal physician about resources that can help you lose weight. Carrying excess weight places additional pressure on your feet. Decrease the time that you stand, walk, or engage in exercises that put a load on your feet. Switch to a nonimpact form of exercise until your tendon heals, such as swimming, pool running, and using an elliptical trainer.



Surgical Treatment
Occasionally, conservative management of Achilles tendon conditions fails. This failure is more common in older male patients and those with longstanding symptoms, those who persist in full training despite symptoms or those who have uncorrected predisposing factors. In these cases, surgery may be indicated. It should be remembered, however, that the rehabilitation program, particularly for severe Achilles tendon injuries, is a slow, lengthy program. Surgery is only indicated when there is failure to progress in the rehabilitation program. Surgery should not be considered unless at least six months of appropriate conservative management has failed to lead to improvement.

Prevention
Do strengthening and stretching exercises to keep calf muscles strong and flexible. Keep your hamstring muscles flexible by stretching. Warm up and stretch adequately before participating in any sports. Always increase the intensity and duration of training gradually. Do not continue an exercise if you experience pain over the tendon. Wear properly fitted running and other sports shoes, including properly fitted arch supports if your feet roll inwards excessively (over-pronate).
