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.
Over-pronation, injury and overstresses of the tendon are some of the most common causes. Risk factors include tight heel cords, poor foot alignment, and recent changes in activities or shoes. During
a normal gait cycle, the upper and lower leg rotate in unison (i.e. internally during pronation and externally during supination). However, when a person over-pronates, the lower leg is locked into
the foot and therefore continues to rotate internally past the end of the contact phase while the femur begins to rotate externally at the beginning of midstance. The Gastrocnemius muscle is attached
to the upper leg and rotates externally while the Soleus muscle is attached to the lower leg and rotates internally during pronation. The resulting counter rotation of the upper and lower leg causes
a shearing force to occur in the Achilles tendon. This counter rotation twists the tendon at its weakest area, namely the Achilles tendon itself, and causes the inflammation. Since the tendon is
avascular, once inflammation sets in, it tends to be chronic.
The primary symptom of Achilles tendon inflammation is pain in the back of the heel, which initially increases when exercise is begun and often lessens as exercise continues. A complete tear of the
Achilles tendon typically occurs with a sudden forceful change in direction when running or playing tennis and is often accompanied by a sensation of having been struck in the back of the ankle and
calf with an object such as a baseball bat.
Confirming Achilles tendonitis may involve imaging tests. X-rays provide images of the bones of the foot and leg. Magnetic resonance imaging (MRI) is useful for detecting ruptures and degeneration of
tissue. Ultrasound shows tendon movement, related damage, and inflammation.
The main treatments for Achilles tendinitis do not involve surgery. It is important to remember that it may take at least 2 to 3 months for the pain to go away. Try putting ice over the Achilles
tendon for 15 to 20 minutes, two to three times per day. Remove the ice if the area gets numb. Changes in activity may help manage the symptoms. Decrease or stop any activity that causes you pain.
Run or walk on smoother and softer surfaces. Switch to biking, swimming, or other activities that put less stress on the Achilles tendon. Your health care provider or physical therapist can show you
stretching exercises for the Achilles tendon. They may also suggest the following changes in your footwear, a brace or boot or cast to keep the heel and tendon still and allow the swelling to go
down, heel lifts placed in the shoe under the heel, shoes that are softer in the areas over and under the heel cushion. Nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin and ibuprofen can
help with pain or swelling. Talk with your health care provider. If these treatments do not improve symptoms, you may need surgery to remove inflamed tissue and abnormal areas of the tendon. Surgery
also can be used to remove the bone spur that is irritating the tendon. Extracorporeal shock wave therapy (ESWT) may be an alternative to surgery for people who have not responded to other
treatments. This treatment uses low-dose sound waves.
Treating this surgically, there are numerous methods to repair the tendon. Most commonly, Achilles tendon is exposed through an incision at the back of the ankle. After identifying both ends of
ruptured tendon, the edges got trimmed and then both ends were sutured together with optimal tension. To get a better outcome with fixation, an anchor may have to be in place in calcaneus, provided
the rupture is very low. Care must be taken to avoid injuries to the nerves located adjacent to the tendon.
Suggestions to reduce your risk of Achilles tendonitis include, icorporate stretching into your warm-up and cool-down routines. Maintaining an adequate level of fitness for your sport. Avoid dramatic
increases in sports training. If you experience pain in your Achilles tendon, rest the area. Trying to ?work through? the pain will only make your injury worse. Wear good quality supportive shoes
appropriate to your sport. If there is foot deformity or flattening, obtain orthoses. Avoid wearing high heels on a regular basis. Maintaining your foot in a ?tiptoe? position shortens your calf
muscles and reduces the flexibility of your Achilles tendon. An inflexible Achilles tendon is more susceptible to injury. Maintain a normal healthy weight.
