The Achilles tendon attaches the calf muscle to the heel bone. Achilles tendonitis is a repetitive strain (overuse) injury involving lower leg muscles and tendons at the point where they attach to the bone, resulting in pain at the back of the ankle. Chronic overuse can lead to small tears within the tendon causing long-term weakening, making the tendon susceptible to rupture, which could result in a need for surgery.
Achilles tendonitis is an overuse injury that is common especially to joggers and jumpers, due to the repetitive action and so may occur in other activities that requires the same repetitive action. Most tendon injuries are the result of gradual wear and tear to the tendon from overuse or ageing. Anyone can have a tendon injury, but people who make the same motions over and over in their jobs, sports, or daily activities are more likely to damage a tendon. A tendon injury can happen suddenly or little by little. You are more likely to have a sudden injury if the tendon has been weakened over time. Common causes of Achilles tendonitis include, over-training or unaccustomed use,?too much too soon?. Sudden change in training surface e.g. grass to bitumen. Flat (over-pronated) feet, High foot arch with tight Achilles tendon. tight hamstring (back of thigh) and calf muscles, toe walking (or constantly wearing high heels). Poorly supportive footwear, hill running. Poor eccentric strength.
In most cases, symptoms of Achilles tendonitis, also sometimes called Achilles tendinitis, develop gradually. Pain may be mild at first and worsen with continued activity. Repeated or continued stress on the Achilles tendon increases inflammation and may cause it to rupture. Partial or complete rupture results in traumatic damage and severe pain, making walking virtually impossible and requiring a long recovery period. Patients with tendinosis may experience a sensation of fullness in the back of the lower leg or develop a hard knot of tissue (nodule).
If you think you have Achilles tendinitis, make an appointment to see your doctor. The doctor will ask you questions about your recent activity and look for signs. The foot not flexing when the calf muscle is pressed ( if Achilles ruptures or tears in half). Swelling on the back of the foot. Pain in the back of the foot. Limited range of motion in ankle. An X-ray or MRI scan can check for tendinitis.
If you have ongoing pain around your Achilles tendon, or the pain is severe, book an appointment with your family physician and ask for a referral to a Canadian Certified Pedorthist. Your Pedorthist will conduct a full assessment of your feet and lower limbs and will evaluate how you run and walk. Based on this assessment, your Pedorthist may recommend a foot orthotic to ease the pressure on your Achilles tendon. As Achilles tendinitis can also be caused by wearing old or inappropriate athletic shoes for your sport, your Pedorthist will also look at your shoes and advise you on whether they have appropriate support and cushioning. New shoes that don?t fit properly or provide adequate support can be as damaging as worn out shoes.
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.
Warm up slowly by running at least one minute per mile slower than your usual pace for the first mile. Running backwards during your first mile is also a very effective way to warm up the Achilles, because doing so produces a gentle eccentric load that acts to strengthen the tendon. Runners should also avoid making sudden changes in mileage, and they should be particularly careful when wearing racing flats, as these shoes produce very rapid rates of pronation that increase the risk of Achilles tendon injury. If you have a tendency to be stiff, spend extra time stretching. If you?re overly flexible, perform eccentric load exercises preventively. Lastly, it is always important to control biomechanical alignment issues, either with proper running shoes and if necessary, stock or custom orthotics.
