Overview

You can feel your Achilles tendon beneath the skin on the back of your ankle. It is a fibrous band of tissue that connects your calf muscles to your heel bone (calcaneus), which allows you to lift your heel off the ground. Most commonly an overuse injury, the term Achilles tendinitis commonly refers to, acute inflammation in the sheath surrounding your tendon, chronic damage to the tendon itself, called tendinosis, a combination of the two. Achilles tendinitis can range from mild inflammation to, in rare cases, a tendon rupture. One type of tendinitis, called insertional Achilles tendinitis, can affect the end of the tendon where it attaches to your heel bone. Achilles tendinitis also can be associated with other foot problems, such as painful flat feet.
Causes
There are two large muscles in the calf. These muscles are important for walking. They create the power needed to push off with the foot or go up on the toes. The large Achilles tendon connects these muscles to the heel. Heel pain is most often due to overuse of the foot. Rarely it is caused by an injury. Tendinitis due to overuse is most common in younger people. It can occur in walkers, runners, or other athletes. Achilles tendinitis may be more likely to occur if you Suddenly increase the amount or intensity of an activity. Your calf muscles are very tight (not stretched out). You run on hard surfaces such as concrete. You run too often, you jump a lot (such as when playing basketball), you do not have shoes with proper support, your foot suddenly turns in or out. Tendinitis from arthritis is more common in middle-aged and elderly people. A bone spur or growth may form in the back of the heel bone. This may irritate the Achilles tendon and cause pain and swelling.
Symptoms
A symptom is something the patient feels and reports, while a sign is something other people, such as a doctor, detect. For example, pain is a symptom, while a rash is a sign. The most typical symptom of Achilles tendinitis is a gradual buildup of pain that deteriorates with time. With Achilles tendinitis, the Achilles tendon may feel sore a few centimeters above where it meets the heel bone. Other possible signs and symptoms of Achilles tendinitis are, the Achilles tendon feels sore a few centimeters above where it meets the heel bone, lower leg feels stiff or lower leg feels slow and weak. Slight pain in the back of the leg that appears after running or exercising, and worsens, pain in the Achilles tendon that occurs while running or a couple of hours afterwards. Greater pain experienced when running fast (such as sprinting), for a long time (such as cross country), or even when climbing stairs. The Achilles tendon swells or forms a bump or the Achilles tendon creaks when touched or moved. Please note that these symptoms, and others similar can occur in other conditions, so for an accurate diagnosis, the patient would need to visit their doctor.
Diagnosis
A doctor or professional therapist will confirm a diagnosis, identify and correct possible causes, apply treatment and prescribe eccentric rehabilitation exercises. An MRI or Ultrasound scan can determine the extent of the injury and indicate a precise diagnosis. Gait analysis along with a physical assessment will identify any possible biomechanical factors such as over pronation which may have contributed to the achilles tendonitis and training methods will be considered. Biomechanical problems can be corrected with the use of orthotic inserts and selection of correct footwear.
Nonsurgical Treatment
In order to treat the symptoms, antiflogistics or other anti-inflammatory therapy are often used. However these forms of therapy usually cannot prevent the injury to live on. Nevertheless patients will always have to be encouraged to execute less burdening activities, so that the burden on the tendon decreases as well. Complete immobilisation should however be avoided, since it can cause atrophy. Passive rehabilitation, Mobilisations can be used for dorsiflexion limitation of the talocrural joint and varus- or valgus limitation of the subtalar joint. Deep cross frictions (15 min). It?s effectiveness is not scientifically proven and gives limited results. Recently, the use of Extracorporal Shock Wave Therapy was proven. Besides that, the application of ice can cause a short decrease in pain and in swelling. Even though cryotherapy 2, 5 was not studied very thoroughly, recent research has shown that for injuries of soft tissue, applications of ice through a wet towel for ten minutes are the most effective measures. Active rehabilitation, An active exercise program mostly includes eccentric exercises. This can be explained by the fact that eccentric muscle training will lengthen the muscle fibres, which stimulates the collagen production. This form of therapy appears successful for mid-portion tendinosis, but has less effect with insertion tendinopathy. The sensation of pain sets the beginning burdening of the patient and the progression of the exercises.
Surgical Treatment
If non-surgical approaches fail to restore the tendon to its normal condition, surgery may be necessary. The foot and ankle surgeon will select the best procedure to repair the tendon, based upon the extent of the injury, the patient?s age and activity level, and other factors.
Prevention
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.
