Also known as: Achilles Tendinosis.
Achilles tendonitis is a condition of irritation and inflammation of the large tendon in the back of the ankle. Achilles tendonitis is a common injury that tends to occur in recreational athletes. Overuse of the Achilles tendon can cause inflammation that can lead to pain and swelling. Achilles tendonitis is differentiated from another common Achilles tendon condition called Achilles tendonosis. Patients with Achilles tendinosis have chronic Achilles swelling and pain as a result of degenerative, microscopic tears within the tendon.
Causes of Achilles Tendonitis
The two most common causes of Achilles tendonitis are:
- Lack of flexibility
- Flat Feet/ Over pronation
Other factors associated with Achilles tendonitis are recent changes in footwear, and changes in exercise training schedules. Often long distance runners will have symptoms of Achilles tendonitis after increasing their mileage or increasing the amount of hill training they are doing. As people age, tendons, like other tissues in the body, become less flexible, more rigid, and more susceptible to injury. Therefore, middle-age recreational athletes are most susceptible to Achilles tendonitis.
Symptoms of Achilles Tendonitis
The main complaint associated with Achilles tendonitis is pain behind the heel. The pain is often most prominent in an area about 2-4 centimeters above where the tendon attaches to the heel. In this location, called the watershed zone of the tendon, the blood supply to the tendon makes this area particularly susceptible. Patients with Achilles tendonitis usually experience the most significant pain after periods of inactivity. Therefore patients tend to experience pain after first walking in the morning and when getting up after sitting for long periods of time. Patients will also experience pain while participating in activities, such as when running or jumping. Achilles tendonitis pain associated with exercise is most significant when pushing off or jumping.
You will be assessed for the above risk factors and insoles may be provided to alleviate the tension and pressure through the tendon. The best treatment of Achilles tendon problems is prevention. Stretching the Achilles tendon before exercise, even at the start of the day, will help to maintain flexibility in the ankle joint. Problems with foot mechanics can also be treated with devices inserted into the shoes. Products such as heel cups, arch supports, and custom orthotics can be used to correct for abnormalities, such as over pronation, and help prevent Achilles tendon injuries.
