Achilles tendonitis is a relatively common
condition characterized by tissue damage and pain in the Achilles tendon. The muscle group at the back of the lower leg is commonly called the calf. The calf comprises of 2 major muscles, one of
which originates from above the knee joint (gastrocnemius), the other of which originates from below the knee joint (soleus). Both of these muscles insert into the heel bone via the Achilles tendon.
During contraction of the calf, tension is placed through the Achilles tendon. When this tension is excessive due to too much repetition or high force, damage to the tendon occurs. Achilles
tendonitis is a condition whereby there is damage to the tendon with subsequent degeneration and inflammation. This may occur traumatically due to a high force going through the tendon beyond what it
can withstand or, more commonly, due to gradual wear and tear associated with overuse.
Poorly conditioned athletes are at the highest risk for developing Achilles tendonitis, also sometimes called Achilles tendinitis. Participating in activities that involve sudden stops and starts and
repetitive jumping (e.g., basketball, tennis, dancing) increases the risk for the condition. It often develops following sudden changes in activity level, training on poor surfaces, or wearing
inappropriate footwear. Achilles tendonitis may be caused by a single incident of overstressing the tendon, or it may result from a series of stresses that produce small tears over time (overuse).
Patients who develop arthritis in the heel have an increased risk for developing Achilles tendonitis. This occurs more often in people who middle aged and older. The condition also may develop in
people who exercise infrequently and in those who are just beginning an exercise program, because inactive muscles and tendons have little flexibility because of inactivity. It is important for
people who are just starting to exercise to stretch properly, start slowly, and increase gradually. In some cases, a congenital (i.e., present at birth) condition causes Achilles tendonitis.
Typically, this is due to abnormal rotation of the foot and leg (pronation), which causes the arch of the foot to flatten and the leg to twist more than normal.
Symptoms of acute achilles tendonitis will be a gradual onset of achilles pain at the back of the ankle, just above the heel bone. This may develop over a period of days. The achilles tendon may be
painful and stiff at the start of exercise and first thing in the morning. As the tendon warms up the pain will go often for it to return later in the day or towards the end of a prolonged training
session. The tendon will be very tender on palpation or pressing in on the achilles tendon or squeezing it from the sides. Chronic achilles tendonitis may follow on from acute achilles tendonitis if
it goes untreated or is not allowed sufficient rest. Chronic achilles tendonitis is a difficult condition to treat, particularly in older athletes who appear to suffer more often.
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.
Your podiatrist may recommend one or more of these treatments to manage your pain. A bandage specifically designed to restrict motion of the tendon. Over the counter, non-steroidal anti-inflammatory
medication (ibuprofen). Custom orthotic shoe inserts to relieve stress on the tendon. Rest. Switching to a low impact exercise such as swimming, that does not stress the tendon. Stretching, massage,
ultrasound and appropriate exercises to strengthen the muscles that support the achilles tendon. In extreme cases, surgery is necessary to remove the damaged tissue and repair any tears.
Not every Achilles tendon injury or condition requires surgery. It is generally understood by doctors and surgeons, that surgery will introduce more scar tissue into the Achilles tendon. This added
scar tissue will be problematic, requiring physical therapy and conservative treatment options post-surgery. If not dealt with properly, your ankle and Achilles tendon could end up in worse condition
than before the surgery! This is why surgery is only performed as a last resort.
If you're just getting started with your training, be sure to stretch after running, and start slowly, increasing your mileage by no more than 10% per week. Strengthen your calf muscles with
exercises such as toe raises. Work low-impact cross-training activities, such as cycling and swimming, into your training.
