Achilles Tendinitis is a painful
condition. Running and walking are made possible by the Achilles tendon, which attaches the calf muscle to the heel bone. Strenuous exercise, jumping, and climbing are all movements that can strain
the tendon and calf muscles, causing an inflammation known as tendinitis. The injury to the Achilles can be mild, requiring only rest and over-the-counter anti-inflammatory drugs, or severe,
necessitating surgical repair of the damaged tendon. Chronic Achilles tendinitis can lead to micro tears in the tissue (tendinosis), which weaken the tendon and put it at risk for severe damage such
as a tear or rupture.
Achilles tendinitis usually results from overuse and not a specific injury or trauma. When the body is subject to repetitive stress, the Achilles tendon is more prone to become inflamed. Other
factors may cause Achilles tendinitis, such as, Sudden increase in physical activity, which can be related to distance, speed or hills, without giving yourself adequate time to adjust to the
heightened activity. With running up hills, the Achilles tendon has to stretch more for each stride, which creates rapid fatigue. Inadequate footwear or training surface. High heels may cause a
problem, because the Achilles tendon and calf muscles are shortened. While exercising in flat, athletic shoes, the tendon is then stretched beyond its normal range, putting abnormal strain on the
tendon. Tight calf muscles which gives the foot a decreased range of motion. The strained calf muscles may also put extra strain on the Achilles tendon. Bone spur where the Achilles tendon attaches
to the heel bone, aggravating the tendon and causing pain.
Paratenonitis presents in younger people. Symptoms start gradually and spontaneously. Aching and burning pain is noted especially with morning activity. It may improve slightly with initial activity,
but becomes worse with further activity. It is aggravated by exercise. Over time less exercise is required to cause the pain. The Achilles tendon is often enlarged, warm and tender approximately 1 to
4 inches above its heel insertion. Sometimes friction is noted with gentle palpation of the tendon during ankle motion. Tendinosis presents similarly but typically in middle-aged people. If severe
pain and limited walking ability are present, it may indicate a partial tear of the tendon.
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,
Treatment approaches for Achilles tendonitis or tendonosis are selected on the basis of how long the injury has been present and the degree of damage to the tendon. In the early stage, when there is
sudden (acute) inflammation, one or more of the following options may be recommended. Immobilization. Immobilization may involve the use of a cast or removable walking boot to reduce forces through
the Achilles tendon and promote healing. Ice. To reduce swelling due to inflammation, apply a bag of ice over a thin towel to the affected area for 20 minutes of each waking hour. Do not put ice
directly against the skin. Oral medications. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, may be helpful in reducing the pain and inflammation in the early stage of the
condition. Orthotics. For those with over-pronation or gait abnormalities, custom orthotic devices may be prescribed. Night splints. Night splints help to maintain a stretch in the Achilles tendon
during sleep. Physical therapy. Physical therapy may include strengthening exercises, soft-tissue massage/mobilization, gait and running re-education, stretching, and ultrasound therapy.
If non-surgical approaches fail to restore the tendon to its normal condition, surgery may be necessary. The foot and ankle surgeon will select the best procedure to repair the tendon, based upon the
extent of the injury, the patient?s age and activity level, and other factors.
Wear shoes that fit correctly and support your feet: Replace your running or exercise shoes before the padding or shock absorption wears out. Shock absorption greatly decreases as the treads on the
bottoms or sides of your shoes begin to wear down. You may need running shoes that give your foot more heel or arch support. You may need shoe inserts to keep your foot from rolling inward. Stretch
before you exercise: Always warm up your muscles and stretch gently before you exercise. Do cool down exercises when you are finished. This will loosen your muscles and decrease stress on your
Achilles tendon. Exercise the right way: If your tendinitis is caused by the way that you exercise, ask a trainer, coach, or your caregiver for help. They can teach you ways to train or exercise to
help prevent Achilles tendinitis. Do not run or exercise on uneven or hard surfaces. Instead, run on softer surfaces such as treadmills, rubber tracks, grass, or evenly packed dirt tracks.
