tendon is a band of connective tissue that anchors muscle to bone. The Achilles tendon is the largest tendon in the body. It attaches the calf muscles to the heel bone (calcaneus) and is very
important because it lets you lift your heel when you start to walk. It also helps you to walk, run or stand on tiptoe. Achilles tendonitis is inflammation of the Achilles tendon. In most cases, it
is a type of overuse injury and is more common in younger people. Professional and weekend athletes can suffer from Achilles tendonitis, but it is also a common overuse injury in people not involved
in sport. Treatment includes rest, non-steroidal anti-inflammatory drugs (NSAIDs), physical therapy and avoiding activities that aggravate the condition.
Like any muscle or tendon in the body, the older we get, the more likely we are to sustain an injury. So middle-aged men and women are most at risk, with a slightly higher risk factor attributed to
males. Those who participate in more intense athletic activities like high impact sports (tennis, running, basketball) are most susceptible to the injury. Certain underlying medical conditions can
also be a contributing factor. Diabetics are more at risk of suffering from Achilles Tendinitis, as are those who are not in great physical shape. Some antibiotics, particularly fluoroquinolones can
make one more likely to suffer a strained Achilles Tendon.
Dull or sharp pain anywhere along the back of the tendon, but usually close to the heel. limited ankle flexibility redness or heat over the painful area a nodule (a lumpy build-up of scar tissue)

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.
Treatment of Achilles tendonitis begins with resting the tendon to allow the inflammation to settle down. In more serious situations, adequate rest may require crutches or immobilization of the
ankle. Learn more about different treatments for Achilles tendonitis, including ice, medications, injections, and surgery.
Surgery is an option of last resort. However, if friction between the tendon and its covering sheath makes the sheath thick and fibrous, surgery to remove the fibrous tissue and repair any tears may
be the best treatment option.
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,
