Your Achilles tendon is located at the back of your foot, just above your heel. It connects your heel to the two muscles of your calf and helps your foot push forward every time you take a step. If the tendon becomes swollen or irritated due to overuse, it can lead to the painful condition called Achilles tendonitis. If Achilles tendonitis goes untreated, it can become a chronic (ongoing) condition that makes just walking around almost impossible. Achilles tendonitis is a very common running injury. But it can also affect basketball players, dancers, or people who put a lot of repeated stress on their feet. It can be very painful.
Achilles tendinitis can be caused by any activity that puts stress on your Achilles tendon. Tendinitis can develop if you run or jump more than usual or exercise on a hard surface. Tendinitis can be caused by shoes that do not fit or support your foot and ankle. Tight tendons and muscles, You may have tight hamstring and calf muscles in your upper and lower leg. Your tendons also become stiffer and easier to injure as you get older. Arthritis, Bony growths caused by arthritis can irritate the Achilles tendon, especially around your heel.
Patients with an Achilles tendon rupture frequently present with complaints of a sudden snap in the lower calf associated with acute, severe pain. The patient reports feeling like he or she has been shot, kicked, or cut in the back of the leg, which may result in an inability to ambulate further. A patient with Achilles tendon rupture will be unable to stand on his or her toes on the affected side. Tendinosis is often pain free. Typically, the only sign of the condition may be a palpable intratendinous nodule that accompanies the tendon as the ankle is placed through its range of motion (ROM). Patients with paratenonitis typically present with warmth, swelling, and diffuse tenderness localized 2-6 cm proximal to the tendon’s insertion. Paratenonitis with tendinosis. This is diagnosed in patients with activity-related pain, as well as swelling of the tendon sheath and tendon nodularity.
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.
Treatment normally includes, A bandage, designed specifically to restrict motion of the tendon. Non-steroidal anti-inflammatory medication. Orthoses (devices to help to support the muscle and relieve stress on the tendon, such as a heel pad or shoe insert. Rest, and switching to an exercise, such as swimming, that does not stress the tendon. Stretching, massage, ultrasound and appropriate exercises to strengthen the weak muscle group in front of the leg and the upper foot flexors. In extreme cases, surgery is performed, to remove fibrous tissue and repair any tears.
As with any surgery there are risks to every procedure depending on a lot of factors, including your age, the severity of your injury and your level of health going into the procedure. It is always best to discuss all possible risks and complications with your doctor, orthopaedic specialist and/or surgeon before the procedure. It’s important to be aware of the risks you may face with any procedure intended to fix or relieve pain from your Achilles tendon injury.
Although Achilles tendinitis cannot be completely prevented, the risk of developing it can be lowered. Being aware of the possible causes does help, but the risk can be greatly reduced by taking the following precautions. Getting a variety of exercise – alternating between high-impact exercises (e.g. running) and low-impact exercise (e.g. swimming) can help, as it means there are days when the Achilles tendon is under less tension. Limit certain exercises – doing too much hill running, for example, can put excessive strain on the Achilles tendon. Wearing the correct shoes and replacing them when worn – making sure they support the arch and protect the heel will create less tension in the tendon. Using arch supports inside the shoe, if the shoe is in good condition but doesn’t provide the required arch support this is a cheaper (and possibly more effective) alternative to replacing the shoe completely. Stretching, doing this before and after exercising helps to keep the Achilles tendon flexible, which means less chance of tendinitis developing. There is no harm in stretching every day (even on days of rest), as this will only further improve flexibility. Gradually increasing the intensity of a workout – Achilles tendinitis can occur when the tendon is suddenly put under too much strain, warming up and increasing the level of activity gradually gives your muscles time to loosen up and puts less pressure on the tendon.
