Achilles tendon attaches the calf muscle to the heel bone. Jumping, climbing and strenuous exercise can strain the tendon and calf muscle, which can cause the type of inflammation known as
tendinitis. This injury can be mild enough that it can be treated by over-the-counter medications or so severe that it must be repaired surgically. Chronic tendinitis can cause microscopic tears in
the muscle which can weaken the tendon and increase the risk for tear or rupture. Symptoms usually include pain and swelling near the ankle. Pain may lead to weakness in the area that increases with
walking and running. Stiffness in the tendon may be worse in the morning.
Some of the causes of Achilles tendonitis include, overuse injury - this occurs when the Achilles tendon is stressed until it develops small tears. Runners seem to be the most susceptible. People who
play sports that involve jumping, such as basketball, are also at increased risk. Arthritis - Achilles tendonitis can be a part of generalised inflammatory arthritis, such as ankylosing spondylitis
or psoriatic arthritis. In these conditions, both tendons can be affected. Foot problems - some people with flat feet or hyperpronated feet (feet that turn inward while walking) are prone to Achilles
tendonitis. The flattened arch pulls on calf muscles and keeps the Achilles tendon under tight strain. This constant mechanical stress on the heel and tendon can cause inflammation, pain and swelling
of the tendon. Being overweight can make the problem worse. Footwear - wearing shoes with minimal support while walking or running can increase the risk, as can wearing high heels. Overweight and
obesity - being overweight places more strain on many parts of the body, including the Achilles tendon. Quinolone antibiotics - can in some instances be associated with inflammatory tenosynovitis
and, if present, will often be bilateral (both Achilles), coming on soon after exposure to the drug.
People with Achilles tendinitis may experience pain during and after exercising. Running and jumping activities become painful and difficult. Symptoms include stiffness and pain in the back of the
ankle when pushing off the ball of the foot. For patients with chronic tendinitis (longer than six weeks), x-rays may reveal calcification (hardening of the tissue) in the tendon. Chronic tendinitis
can result in a breakdown of the tendon, or tendinosis, which weakens the tendon and may cause a rupture.
When diagnosing Achilles tendinitis, a doctor will ask the patient a few questions about their symptoms and then perform a physical examination. To perform a physical exam on the Achilles tendon, the
doctor will lightly touch around the back of the ankle and tendon to locate the source of the pain or inflammation. They will also test the foot and ankle to see if their range of motion and
flexibility has been impaired. The doctor might also order an imaging test to be done on the tendon. This will aid in the elimination of other possible causes of pain and swelling, and may help the
doctor assess the level of damage (if any) that has been done to the tendon. Types of imaging tests that could be used for diagnosing Achilles tendinitis are MRI (Magnetic resonance imaging), X-ray,
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
Most people will improve with simple measures or physiotherapy. A small number continue to have major problems which interfere with their lifestyle. In this situation an operation may be considered.
If an operation is being considered, the surgeon will interview you and examine you again and may want you to have further treatment before making a decision about an operation. Before undergoing
Achilles tendonitis surgery, London based patients, and those who can travel, will be advised to undergo a scan, which will reveal whether there is a problem in the tendon which can be corrected by
surgery. Patients will also have the opportunity to ask any questions and raise any concerns that they may have, so that they can proceed with the treatment with peace of mind.
Regardless of whether the Achilles injury is insertional or non-insertional, a great method for lessening stress on the Achilles tendon is flexor digitorum longus exercises. This muscle, which
originates along the back of the leg and attaches to the tips of the toes, lies deep to the Achilles. It works synergistically with the soleus muscle to decelerate the forward motion of the leg
before the heel leaves the ground during propulsion. This significantly lessens strain on the Achilles tendon as it decelerates elongation of the tendon. Many foot surgeons are aware of the
connection between flexor digitorum longus and the Achilles tendon-surgical lengthening of the Achilles (which is done to treat certain congenital problems) almost always results in developing hammer
toes as flexor digitorum longus attempts to do the job of the recently lengthened tendon. Finally, avoid having cortisone injected into either the bursa or tendon-doing so weakens the tendon as it
shifts production of collagen from type one to type three. In a recent study published in the Journal of Bone Joint Surgery(9), cortisone was shown to lower the stress necessary to rupture the
Achilles tendon, and was particularly dangerous when done on both sides, as it produced a systemic effect that further weakened the tendon.
