Achilles tendinitis. Achilles
tendonitis is inflammation of the Achilles tendon, the largest tendon in the body, which runs from the calf to the heel bone. Noninsertional Achilles tendonitis affects fibers in the middle of the
tendon. Insertional Achilles tendonitis affects the lower portion of the tendon where it attaches to the heel bone. Both types can result from repetitive stress to the tendon or from overstressing
the tendon during exercise. Damaged tendon fibers can calcify and bone spurs can form where the tendon attaches to the bone. Symptoms may include pain and stiffness of the tendon - which may occur
from either inactivity (such as first thing in the morning) or after activity - thickening or swelling of the tendon or bone spurs.
Tight or fatigued calf muscles, which transfer the burden of running to the Achilles. This can be due to poor stretching, rapidly increasing distance, or over-training excessive hill running or speed
work, both of which stress the Achilles more than other types of running. Inflexible running shoes, which, in some cases, may force the Achilles to twist. Runners who overpronate (feet rotate too far
inward on impact) are most susceptible to Achilles tendinitis.
People with achilles tendinitis experience mild aching on the back of the leg close to the heel after increased activity. Stiffness in the back of the ankle when you first wake up in the morning,
which subsides after mild activity. In some cases, the area may have swelling, thickening or be warm to the touch. Tenderness to touch along the tendon in the back of the ankle. Pain when the tendon
is stretched (i.e. when you lift your foot/toes up).
A thorough subjective and objective examination from a physiotherapist is usually sufficient to diagnose an Achilles injury such as Achilles tendonitis. Occasionally, further investigations such as
an Ultrasound, X-ray or MRI scan may be required to assist with diagnosis and assess the severity of the condition.
Treatment depends on severity of pain. The most effective long-term treatment for Achilles tendinitis/tendinopathy is physical therapy, particularly therapy that focuses on eccentric muscle/tendon
strengthening. Calf and Achilles stretching are also an important part of the treatment. In severe cases, treatment may begin with a period of rest and immobilization in order to calm down the tendon
before physical therapy is initiated. Anti-inflammatories may be prescribed. Avoiding activities that aggravate the Achilles tendon will help the healing process. Improvement and resolution of
symptoms can take months. Exercise might be the cause of Achilles tendonitis, but it can also help prevent it and aid in recovery. Healing will occur more quickly if there is no pressure on the
injured tendon, and if the foot is at least partially immobilized.
In cases of severe, long-term Achilles tendonitis the sheath may become thick and fibrous. In these cases surgery may be recommended. Surgery aims to remove the fibrous tissue and repair any tears in
the tendon. A cast or splint will be required after the operation and a recovery program including physiotherapy, specific exercises and a gradual return to activity will be planned.
Your podiatrist will work with you to decrease your chances of re-developing tendinitis. He or she may create custom orthotics to help control the motion of your feet. He or she may also recommend
certain stretches or exercises to increase the tendon's elasticity and strengthen the muscles attached to the tendon. Gradually increasing your activity level with an appropriate training
schedule-building up to a 5K run, for instance, instead of simply tackling the whole course the first day-can also help prevent tendinitis.
