Achilles Tendonitis The Facts

Overview
Achilles tendinitis describes an inflammatory change of the Achilles tendon without a tear of the tendon. Achilles tendinitis may be acute or chronic. The onset of pain is usually unilateral but may be found bilaterally. Achilles tendinitis is common in the third or fourth decade of life in patients who are active with sports or in jobs that require physical labor. Pain is described at the insertion of the tendon in the heel bone or in the body of the tendon.

Causes
There are hundreds of tendons scattered throughout our body, but it tends to be a small handful of specific tendons that cause problems. These tendons usually have an area of poor blood supply that leads to tissue damage and poor healing response. This area of a tendon that is prone to injury is called a "watershed zone," an area when the blood supply to the tendon is weakest. In these watershed zones, they body has a hard time delivering oxygen and nutrients necessary for tendon healing, that's why we see common tendon problems in the same parts of the body. Tendonitis is most often an overuse injury. Often people begin a new activity or exercise that causes the tendon to become irritated. Tendon problems are most common in the 40-60 year old age range. Tendons are not as elastic and forgiving as in younger individuals, yet bodies are still exerting with the same force. Occasionally, there is an anatomical cause for tendonitis. If the tendon does not have a smooth path to glide along, it will be more likely to become irritated and inflamed. In these unusual situations, surgical treatment may be necessary to realign the tendon.

Symptoms
Gradual onset of pain and stiffness over the tendon, which may improve with heat or walking and worsen with strenuous activity. Tenderness of the tendon on palpation. There may also be crepitus and swelling. Pain on active movement of the ankle joint. Ultrasound or MRI may be necessary to differentiate tendonitis from a partial tendon rupture.

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
NSAIDS like ibuprofen are often prescribed to help manage the pain and inflammation. Steroids are often recommended when patients do not respond to NSAID treatment. They are often most effective when injected directly into the inflamed and swollen area. Physiotherapy is a great way to stretch and strengthen the Achilles tendon. A good physical therapist will also teach the patient techniques which give better foot support during exercise (taping, wrapping, etc?). Orthotics, assistive devices and insoles can be used to cushion and cradle the arch of the foot during the healing process. Shock Wave Therapy. This is the newest form of treatment and uses concentrated sound waves to stimulate healing in the affected area. This form of treatment is reserved for heel pain that is unresponsive to other forms of treatment.


Surgical Treatment
Surgery is considered the last resort and is often performed by an orthopedic surgeon. It is only recommended if all other treatment options have failed after at least six months. In this situation, badly damaged portions of the tendon may be removed. If the tendon has ruptured, surgery is necessary to re-attach the tendon. Rehabilitation, including stretching and strength exercises, is started soon after the surgery. In most cases, normal activities can be resumed after about 10 weeks. Return to competitive sport for some people may be delayed for about three to six months.

Prevention
Achilles tendinitis cannot always be prevented but the following tips will help you reduce your risk. If you are new to a sport, gradually ramp up your activity level to your desired intensity and duration. If you experience pain while exercising, stop. Avoid strenuous activity that puts excessive stress on your Achilles tendon. If you have a demanding workout planned, warm up slowly and thoroughly. Always exercise in shoes that are in good condition and appropriate for your activity or sport. Be sure to stretch your calf muscles and Achilles tendon before and after working out. If you suffer from Achilles tendinitis make sure you treat it properly and promptly. If self-care techniques don?t work, don?t delay. Book a consultation with a foot care expert or you may find yourself sidelined from your favourite sports and activities.
