The Achilles tendon is the thickest and strongest tendon in your body, connecting your calf muscles to the back of your heel. Virtually all of the force generated when you ?toe off? the ground during running is transmitted by the Achilles, and this force can be as much as three times your body weight. And the faster you run, the more strain you put on the Achilles tendon. As such, it?s prone to injury in many runners, but particularly those who do a lot of fast training, uphill running, or use a forefoot-striking style. Achilles tendon injuries account for 5-12% of all running injuries, and occur disproportionately in men. This may be because of the faster absolute speeds men tend to train at, or may be due to other biomechanical factors.
There are a number of causes and risk factors associated with Achilles Tendinitis. One of the most common causes is simply a lack of conditioning. If the tendon, and muscles that connect to the tendon, have not been trained or conditioned, this can lead to a weakness that may result in an Achilles injury. Overtraining is also associated with Achilles Tendinitis. Doing too much, too soon places excessive strain on the Achilles tendon and doesn’t allow the tendon enough time to recovery properly. Over time small tears and general degeneration result in a weakening of the tendon, which leads to inflammation and pain. Other causes of Achilles injury include a lack of warming up and stretching. Wearing inadequate footwear, running or training on uneven ground, and simply standing on, or in something you’re not meant to. Biomechanical problems such as high arched feet or flat feet can also lead to Achilles injuries.
The main symptom of Achilles tendonitis is a feeling of pain and swelling in your heel as you walk or run. Other symptoms include tight calf muscles and limited range of motion when flexing the foot. This condition can also make the skin in your heel feel overly warm to the touch.
Physicians usually pinch your Achilles tendon with their fingers to test for swelling and pain. If the tendon itself is inflamed, your physician may be able to feel warmth and swelling around the tissue, or, in chronic cases, lumps of scar tissue. You will probably be asked to walk around the exam room so your physician can examine your stride. To check for complete rupture of the tendon, your physician may perform the Thompson test. Your physician squeezes your calf; if your Achilles is not torn, the foot will point downward. If your Achilles is torn, the foot will remain in the same position. Should your physician require a closer look, these imaging tests may be performed. X-rays taken from different angles may be used to rule out other problems, such as ankle fractures. MRI (magnetic resonance imaging) uses magnetic waves to create pictures of your ankle that let physicians more clearly look at the tendons surrounding your ankle joint.
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.
It is important to understand that surgery may not give you 100% functionality of your leg, but you should be able to return to most if not all of your pre-injury activities. These surgical procedures are often performed with very successful results. What truly makes a difference is your commitment to a doctor recommended rehabilitation program after surgery as there is always a possibility of re-injuring your tendon even after a surgical procedure. One complication of surgical repair for Achilles tendon tear is that skin can become thin at site of incision, and may have limited blood flow.
Stretching of the gastrocnemius (keep knee straight) and soleus (keep knee bent) muscles. Hold each stretch for 30 seconds, relax slowly. Repeat stretches 2 – 3 times per day. Remember to stretch well before running strengthening of foot and calf muscles (eg, heel raises) correct shoes, specifically motion-control shoes and orthotics to correct overpronation. Gradual progression of training programme. Avoid excessive hill training. Incorporate rest into training programme.
