Achilles tendonitis is a condition wherein the Achilles tendon, at or near its insertion to back of the heel, becomes inflamed and causes pain. The Achilles tendon is one of the longest and strongest tendons in the body. It is avascular (not supplied with blood vessels) so it can be slow to heal. The Achilles tendon is formed in the lower third of the leg. Two muscles join to form the Achilles tendon, the Gastrocnemius and the Soleus which are commonly referred to as the calf muscle. The Achilles tendon works as an anti-pronator which means it helps to prevent the foot from rolling inward.
In some cases, Achilles Tendinitis can be caused by physical activity without a proper warm up or trauma, such as falling, to cause an overstressing of the muscle and tendon. Other causes include repetitive overuse syndrome, such as a job that required frequent heel lifting. Biomechanical causes such as pronation (or fallen arches) will cause the heel (calcaneus) to lean slightly, putting the undue stress on the Achilles tendon and the calf muscles. Most pain can be felt at the back of the heel or the point at which the calf muscle becomes a tendon three quarters of the distance down from the knee. Discomfort can be felt especially when jumping or when lifting the heel off the ground. Swelling and redness can often be seen at the back of the heel and touching the area would cause a tender sensation. In extreme cases, the tendon can become torn or rupture entirely which would cause bruising or an inability to put pressure on the foot.
Symptoms of acute achilles tendonitis will be a gradual onset of achilles pain at the back of the ankle, just above the heel bone. This may develop over a period of days. The achilles tendon may be painful and stiff at the start of exercise and first thing in the morning. As the tendon warms up the pain will go often for it to return later in the day or towards the end of a prolonged training session. The tendon will be very tender on palpation or pressing in on the achilles tendon or squeezing it from the sides. Chronic achilles tendonitis may follow on from acute achilles tendonitis if it goes untreated or is not allowed sufficient rest. Chronic achilles tendonitis is a difficult condition to treat, particularly in older athletes who appear to suffer more often.
Laboratory studies usually are not necessary in evaluating and diagnosing an Achilles tendon rupture or injury, although evaluation may help to rule out some of the other possibilities in the differential diagnosis. Imaging studies. Plain radiography: Radiographs are more useful for ruling out other injuries than for ruling in Achilles tendon ruptures. Ultrasonography: Ultrasonography of the leg and thigh can help to evaluate the possibility of deep venous thrombosis and also can be used to rule out a Baker cyst; in experienced hands, ultrasonography can identify a ruptured Achilles tendon or the signs of tendinosis. Magnetic resonance imaging (MRI): MRI can facilitate definitive diagnosis of a disrupted tendon and can be used to distinguish between paratenonitis, tendinosis, and bursitis.
As with most soft tissue injuries the initial treatment is RICE – Rest, Ice, Compression and Elevation. In the early phase you?ll be unable to walk without a limp, so your Achilles tendon needs some active rest from weight-bearing loads. You may need to be non or partial-weight-bearing, utilise crutches, a wedged achilles walking boot or heel wedges to temporarily relieve some of the pressure on the Achilles tendon. Your physiotherapist will advise you on what they feel is best for you. Ice is a simple and effective modality to reduce your pain and swelling. Please apply for 20-30 minutes each 2 to 4 hours during the initial phase or when you notice that your injury is warm or hot. Anti-inflammatory medication (if tolerated) and natural substances eg arnica may help reduce your pain and swelling. However, it is best to avoid anti-inflammatory drugs during the initial 48 to 72 hours when they may encourage additional bleeding. Most people can tolerate paracetamol as a pain reducing medication. As you improve a kinesio style supportive taping will help to both support the injured soft tissue.
Not every Achilles tendon injury or condition requires surgery. It is generally understood by doctors and surgeons, that surgery will introduce more scar tissue into the Achilles tendon. This added scar tissue will be problematic, requiring physical therapy and conservative treatment options post-surgery. If not dealt with properly, your ankle and Achilles tendon could end up in worse condition than before the surgery! This is why surgery is only performed as a last resort.
Achilles tendinitis cannot always be prevented but the following tips will help you reduce your risk. If you are new to a sport, gradually ramp up your activity level to your desired intensity and duration. If you experience pain while exercising, stop. Avoid strenuous activity that puts excessive stress on your Achilles tendon. If you have a demanding workout planned, warm up slowly and thoroughly. Always exercise in shoes that are in good condition and appropriate for your activity or sport. Be sure to stretch your calf muscles and Achilles tendon before and after working out. If you suffer from Achilles tendinitis make sure you treat it properly and promptly. If self-care techniques don?t work, don?t delay. Book a consultation with a foot care expert or you may find yourself sidelined from your favourite sports and activities.
