tendinitis is an overuse injury of the Achilles tendon, the band of tissue that connects calf muscles at the back of the lower leg to your heel bone. Achilles tendinitis most commonly occurs in
runners who have suddenly increased the intensity or duration of their runs. It's also common in middle-aged people who play sports, such as tennis or basketball, only on the weekends. Most cases of
Achilles tendinitis can be treated with relatively simple, at-home care under your doctor's supervision. Self-care strategies are usually necessary to prevent recurring episodes. More-serious cases
of Achilles tendinitis can lead to tendon tears (ruptures) that may require surgical repair.
The Achilles tendon is a strong band of connective tissue that attaches the calf muscle to the heel bone. When the muscle contracts, the tendon transmits the power of this contraction to the heel,
producing movement. The Achilles tendon moves through a protective sheath and is made up of thousands of tiny fibres. It is thought that Achilles tendonitis develops when overuse of the tendon causes
the tiny fibres that make up the tendon to tear. This causes inflammation, pain and swelling. As the tendon swells it can begin to rub against the sheath surrounding it, irritating the sheath and
causing it too to become inflamed and swollen. It has a poor blood supply, which can make it susceptible to injury and can make recovery from injury slow. Factors that can lead to the development of
Achilles tendonitis include, tight or weak calf muscles, rapidly increasing the amount or intensity of exercise. Hill climbing or stair climbing exercises. Changes in footwear, particularly changing
from wearing high-heeled shoes to wearing flat shoes. Wearing inadequate or inappropriate shoes for the sporting activity being undertaken. Not adequately warming up and stretching prior to exercise.
A sudden sharp movement that causes the calf muscles to contract and the stress on the Achilles tendon to be increased. This can cause the tendon fibres to tear.
Recurring localized pain, sometimes severe, along the tendon during or a few hours after running. Morning tenderness about an inch and a half above the point where the Achilles tendon is attached to
the heel bone. Sluggishness in your leg. Mild or severe swelling. Stiffness that generally diminishes as the tendon warms up with use.
Laboratory studies usually are not necessary in evaluating and diagnosing an Achilles tendon rupture or injury, although evaluation may help to rule out some of the other possibilities in the
differential diagnosis. Imaging studies. Plain radiography: Radiographs are more useful for ruling out other injuries than for ruling in Achilles tendon ruptures. Ultrasonography: Ultrasonography of
the leg and thigh can help to evaluate the possibility of deep venous thrombosis and also can be used to rule out a Baker cyst; in experienced hands, ultrasonography can identify a ruptured Achilles
tendon or the signs of tendinosis. Magnetic resonance imaging (MRI): MRI can facilitate definitive diagnosis of a disrupted tendon and can be used to distinguish between paratenonitis, tendinosis,
Self-care strategies include the following steps, often known by the acronym R.I.C.E, Rest. You may need to avoid exercise for several days or switch to an activity that doesn't strain the Achilles
tendon, such as swimming. In severe cases, you may need to wear a walking boot and use crutches. Ice. To decrease pain or swelling, apply an ice pack to the tendon for about 15 minutes after
exercising or when you experience pain. Compression. Wraps or compressive elastic bandages can help reduce swelling and reduce movement of the tendon. Elevation. Raise the affected foot above the
level of your heart to reduce swelling. Sleep with your affected foot elevated at night.
Surgery for an Achilles tendon rupture can be done with a single large incision, which is called open surgery. Or it can be done with several small incisions. This is called percutaneous surgery. The
differences in age and activity levels of people who get surgery can make it hard to know if Achilles tendon surgery is effective. The success of your surgery can depend on, your surgeon's
experience. The type of surgery you have. How damaged the tendon is. How soon after rupture the surgery is done. How soon you start your rehab program after surgery. How well you follow your rehab
program. Talk to your surgeon about his or her surgical experience. Ask about his or her success rate with the technique that would best treat your condition.
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.
