Achilles tendinitis (tendonitis) or Achilles tendon inflammation occurs when the Achilles tendon becomes inflamed, as a result, of the Achilles tendon being put under too much strain. The Achilles
tendon joins the calf muscles to the heel bone, and is found at the back of a person's lower leg. It is the largest tendon in the body and can endure great force, but is still susceptible to injury.
Achilles tendinitis is usually the result of strenuous, high impact exercise, such as running. If ignored, Achilles tendinitis can lead to the tendon tearing or rupturing, and therefore it is
important to seek the necessary treatment. Sometimes, treatment can be as simple as getting rest or changing an exercise routine. However, in more severe cases, surgery may be required.
Unusual use or overuse of the lower leg muscles and Achilles tendon is usually the cause of Achilles tendinitis. Repetitive jumping, kicking, and sprinting can lead to Achilles tendinitis in both
recreational and competitive athletes. Runners, dancers, and athletes over age 65 are especially at risk. Sudden increases in training or competition can also inflame your Achilles tendon. For
example, adding hills, stair-climbing, or sprinting to your running workout puts extra stress on your Achilles tendon. Improper technique during training can also strain the tendon. Intense running
or jumping without stretching and strengthening your lower leg muscles can put you at risk regardless of your age or fitness level. Running on tight, exhausted, or fatigued calf muscles can put added
stress on your Achilles tendon, as your tendon may not be ready to quickly start a workout after a period of inactivity. Direct blows or other injuries to the ankle, foot, or lower leg may pull your
Achilles tendon too far and stretch the tissue. A hard contraction of the calf muscles, such as can happen when you push for the final sprint in a race, can strain the tendon. People whose feet roll
inward, a condition called overpronation, are particularly at risk. Sometimes, shoes with too much heel cushioning put extra strain on the Achilles tendon.
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.
X-rays are usually normal in patients with Achilles tendonitis, but are performed to evaluate for other possible conditions. Occasionally, an MRI is needed to evaluate a patient for tears within the
tendon. If there is a thought of surgical treatment an MRI may be helpful for preoperative evaluation and planning.
Tendon inflammation should initially be treated with ice, gentle calf muscle stretching, and use of NSAIDs. A heel lift can be placed in the shoes to take tension off the tendon. Athletes should be
instructed to avoid uphill and downhill running until the tendon is not painful and to engage in cross-training aerobic conditioning. Complete tears of the Achilles tendon usually require surgical
Achilles tendon repair surgery is often used to repair a ruptured or torn Achilles tendon, the strong fibrous cord that connects the two large muscles in the back of your calf to your heel bone.
These muscles (the gastrocnemius and the soleus) create the power needed to push off with your foot or rise up on your toes. Achilles tendon ruptures are quite common. Most happen during recreational
activities that require sudden bursts of muscle power in the legs. Often a torn Achilles tendon can be diagnosed with a physical examination. If swelling is present, the orthopaedist may delay the
Achilles tendon surgery until it subsides.
A 2014 study looked at the effect of using foot orthotics on the Achilles tendon. The researchers found that running with foot orthotics resulted in a significant decrease in Achilles tendon load
compared to running without orthotics. This study indicates that foot orthoses may act to reduce the incidence of chronic Achilles tendon pathologies in runners by reducing stress on the Achilles
tendon1. Orthotics seem to reduce load on the Achilles tendon by reducing excessive pronation,
