Achilles Tendonitis

Overview

Achilles tendonitis is an iInflammation in the tendon of the calf muscle, where it attaches to the heel bone. Achilles tendonitis causes pain and stiffness at the back of the leg, near the heel. Achilles tendonitis can be caused by overuse of the Achilles tendon, overly tight calf muscles or Achilles tendons, excess uphill running, a sudden increase in the intensity of training or the type of shoes worn to run, or wearing high heels at work and then switching to a lower-heeled workout shoe. Achilles tendonitis causes pain, tenderness, and often swelling over the Achilles tendon. There is pain on rising up on the toes and pain with stretching of the tendon. The range of motion of the ankle may be limited. Treatment includes applying ice packs to the Achilles tendon, raising the lower leg, and taking an anti-inflammatory medication. In some severe cases of Achilles tendonitis, a cast may be needed for several weeks. A heel lift insert may also be used in shoes to prevent future overstretching of the Achilles tendon. Exerting rapid stress on the Achilles tendon when it is inflamed can result in rupture of the tendon.

Causes

Achilles tendonitis is a common sports injury caused by repeated or intense strain on the tendon. But non-athletes also can get it if they put a lot of stress on their feet. Other things that contribute to Achilles tendonitis include. An increase in activity. Starting a training program after a period of inactivity or adding miles or hills to a jogging regimen are two examples of things that put people at risk for Achilles tendonitis. Sports that require sudden starts and stops; for example, tennis and basketball. A change in footwear, or wearing old or badly fitting shoes. New shoes, worn-out shoes, or the wrong size shoes can cause a person’s feet to overcompensate and put stress on the Achilles tendon. Additionally, wearing high heels all the time can cause the tendon and calf muscles to get shorter, and the switch to flat shoes and exercise can put extra strain on the heel. Running up hills. Going uphill forces the Achilles tendon to stretch beyond its normal range. Weak calf muscles, flat arches, “overpronation” (feet that roll in when running), or “oversupination” (feet that roll out when running). Overpronation and oversupination make the lower leg rotate and put a twisting stress on the tendon. Exercising without warming up. Tight calf muscles or muscles that lack flexibility decrease a person’s range of motion and put an extra strain on the tendon. Running or exercising on a hard or uneven surface or doing lunges or plyometrics without adequate training. A traumatic injury to the Achilles tendon.

Symptoms

Common symptoms of Achilles tendinitis include, pain and stiffness along the Achilles tendon in the morning, pain along the tendon or back of the heel that worsens with activity, Severe pain the day after exercising, thickening of the tendon, bone spur (insertional tendinitis) swelling that is present all the time and gets worse throughout the day with activity, If you have experienced a sudden “pop” in the back of your calf or heel, you may have ruptured (torn) your Achilles tendon. See your doctor immediately if you think you may have torn your tendon.

Diagnosis

Your physiotherapist or sports doctor can usually confirm the diagnosis of Achilles tendonitis in the clinic. They will base their diagnosis on your history, symptom behaviour and clinical tests. Achilles tendons will often have a painful and prominent lump within the tendon. Further investigations include US scan or MRI. X-rays are of little use in the diagnosis.

Nonsurgical Treatment

Take a course (5 – 7 days) of non-steroidal anti-inflammatory drugs(ibuprofen/voltaren/cataflam/mobic) available from your general practitioner or pharmacist. Apply ice to the Achilles – for 10 minutes every 2 hours, in order to reduce the inflammation. Avoid weight-bearing activities and keep foot elevated where possible. Self-massage – using arnica oil or anti-inflammatory gel. Rub in semi-circles in all directions away from the knotted tissue, three times a day once the nodule is gone, stretch the calf muscle gently do not start running until you can do heel raises and jumping exercises without pain return to running gradually full recovery is usually between six to eight weeks.

Surgical Treatment

Percutaneous Achilles Tendon Surgery. During this procedure the surgeon will make 3 to 4 incisions (approx. 2.5 cm long) on both sides of the Achilles tendon. Small forceps are used to free the tendon sheath (the soft tissue casing around your Achilles tendon) to make room for the surgeon to stitch/suture any tears. Skilled surgeons may perform a percutaneous achilles tendon surgery with ultrasound imaging techniques to allow for blink suturing with stab incisions made by a surgical suture needle. This procedure can be done in 3 different ways depending on the preference and experience of your surgeon. Instead of making several 2.5 cm incisions for this procedure, some surgeons will use guided imaging with an ultrasound to see the Achilles tendon tissue without having to open up your ankle. For this technique, they will use a surgical needle to repeatedly stab your Achilles tendon. These “stab incisions” will allow the surgeon to “blindly” suture your tendon without seeing the actual tissue. As another option – some surgeons will only make 1 to 3 incisions for smaller surgical implements to repair your tendon while relying on imaging ultrasound to see your damaged tissue. During either procedure the use of ultrasound imaging or endoscopic techniques requires a very skilled surgeon.

Prevention

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.
