The Achilles tendon is the thickest and strongest tendon in your body, connecting your calf muscles to the back of your heel. Virtually all of the force generated when you ?toe off? the ground during running is transmitted by the Achilles, and this force can be as much as three times your body weight. And the faster you run, the more strain you put on the Achilles tendon. As such, it?s prone to injury in many runners, but particularly those who do a lot of fast training, uphill running, or use a forefoot-striking style. Achilles tendon injuries account for 5-12% of all running injuries, and occur disproportionately in men. This may be because of the faster absolute speeds men tend to train at, or may be due to other biomechanical factors.
Tendinitis typically develops after abrupt changes in activity or training level, use of poorly fit or worn footwear, or training on uneven or dense running surfaces. Overuse prior to sufficient training is generally the cause. This is due to forces 8-10 times the body weight acting on the tendon during physical activity. Achilles injuries range from inflammation to a breakdown in the tendon. Pain is generally felt low on the back of the heel due to the low vascularity and susceptibility for inflammation. Pain higher on the Achilles is generally more muscular pain and less tendonitis. If swollen spots or knots are found along the tendon, or if the tendon feels jagged, cease activity and seek professional medical care.
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).
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.
As with all conditions, your Doctor should be consulted. Even minor symptoms can represent significant damage to the Achilles tendon. It is recommended that medical advice be sought as soon as symptoms are experienced. Applying ice to the injury on a regular basis can reduce inflammation associated with Achilles Tendonosis. Following the initial injury, ice should be applied for periods of 15 minutes every hour. Resting the injured ankle may be necessary. This can be a problem for athletes who need to train regularly. The degree of rest required depends on the severity and type of Achilles Tendonosis. Your Health Care Professional will advise you about what activities should be limited while the injury is repairing. Fast uphill and downhill running is not advised while an Achilles Tendinosis injury is healing. Anti-inflammatory, analgesic medications such as those containing aspirin may help control pain and inflammation. Self-massage with heat-inducing creams and liniments may be of assistance. Wearing heel-lifts or pads in shoes can reduce the tension in the Achilles tendon. Physiotherapy may assist in the repair of a damaged Achilles tendon. Physiotherapists may recommend exercises to strengthen the tendon to reduce the chances of future injury. Regular stretching of the hamstring muscles (at the back of the calf) can help the repair process. This should only be done when the injury has repaired enough not to cause pain during this stretching. Taping the ankle and wearing appropriate running shoes may help to control movement in the ankle and prevent further injury.
In most surgeries, damaged tissue is cleaned out before surgeons make the necessary repairs. However, a new minimally-invasive surgery to repair a torn Achilles tendon actually uses the damaged tissue to help repair the tear. The percutaneous Achilles repair system, or PARS technique, enables surgeons to better repair a torn Achilles tendon through a smaller incision. This procedure was recently performed at Houston Methodist Hospital to treat an NFL cornerback, getting him back on field for this season.
To lower your risk of Achilles tendonitis, stretch your calf muscles. Stretching at the beginning of each day will improve your agility and make you less prone to injury. You should also try to stretch both before and after workouts. To stretch your Achilles, stand with a straight leg, and lean forward as you keep your heel on the ground. If this is painful, be sure to check with a doctor. It is always a good idea to talk to your doctor before starting a new exercise routine. Whenever you begin a new fitness regimen, it is a good idea to set incremental goals. Gradually intensifying your physical activity is less likely to cause injury. Limiting sudden movements that jolt the heels and calves also helps to reduce the risk of Achilles tendonitis. Try combining both high- and low-impact exercises in your workouts to reduce stress on the tendon. For example, playing basketball can be combined with swimming. It doesn?t matter if you?re walking, running, or just hanging out. To decrease pressure on your calves and Achilles tendon, it?s important to always wear the right shoes. That means choosing shoes with proper cushioning and arch support. If you?ve worn a pair of shoes for a long time, consider replacing them or using arch supports. Some women feel pain in the Achilles tendon when switching from high heels to flats. Daily wearing of high heels can both tighten and shorten the Achilles tendon. Wearing flats causes additional bending in the foot. This can be painful for the high-heel wearer who is not accustomed to the resulting flexion. One effective strategy is to reduce the heel size of shoes gradually. This allows the tendon to slowly stretch and increase its range of motion.
