Overview<br>The Achilles is a large tendon that connects two major calf muscles to the back of the heel bone. If this tendon is overworked and tightens, the collagen fibres of the tendon may break, causing inflammation and pain. This can result in scar tissue formation, a type of tissue that does not have the flexibility of tendon tissue. Four types of Achilles injuries exist, 1) Paratendonitis - involves a crackly or crepitus feeling in the tissues surrounding the Achilles tendon. 2) Proliferative Tendinitis - the Achilles tendon thickens as a result of high tension placed on it. 3) Degenerative Tendinitis - a chronic condition where the Achilles tendon is permanently damaged and does not regain its structure. 4) Enthesis - an inflammation at the point where the Achilles tendon inserts into the heel bone.<br><br>Causes<br>Achilles tendonitis occurs in sports such as running, jumping, dancing and tennis. Other risk factors include participation in a new sporting activity or increasing the intensity of participation. Poor running technique, excessive pronation of the foot and poorly fitting footwear may contribute. In cyclists, the problem may be a low saddle, which causes extra dorsiflexion of the ankle when pedalling. Quinolone antibiotics (eg, ciprofloxacin, ofloxacin) can cause inflammation of tendons and predispose them to rupture.<br><br>Symptoms<br>Symptoms of Achilles tendonitis include, pain in the back of the heel, difficulty walking, sometimes the pain makes walking impossible, swelling, tenderness and warmth of the Achilles tendon. Achilles tendonitis is graded according to how severe it is, mild - pain in the Achilles tendon during a particular activity (such as running) or shortly after. Moderate - the Achilles tendon may swell. In some cases, a hard lump (nodule) may form in the tendon. Severe - any type of activity that involves weight bearing causes pain of the Achilles tendon. Very occasionally, the Achilles tendon may rupture (tear). When an Achilles tendon ruptures, it is said to feel like a hard whack on the heel.<br><br>Diagnosis<br>A podiatrist can usually make the diagnosis by clinical history and physical examination alone. Pain with touching or stretching the tendon is typical. There may also be a visible swelling to the tendon. The patient frequently has difficulty plantarflexing (pushing down the ball of the foot and toes, like one would press on a gas pedal), particularly against resistance. In most cases X-rays don't show much, as they tend to show bone more than soft tissues. But X-rays may show associated degeneration of the heel bone that is common with Achilles Tendon problems. For example, [http://daniel3freeman46.jimdo.com/2015/06/23/factors-behind-hammer-toe-deformity heel spurs], calcification within the tendon, avulsion fractures, periostitis (a bruising of the outer covering of the bone) may all be seen on X-ray. In cases where we are uncertain as to the extent of the damage to the tendon, though, an MRI scan may be necessary, which images the soft tissues better than X-rays. When the tendon is simply inflamed and not severely damaged, the problem may or may not be visible on MRI. It depends upon the severity of the condition.<br><br>Nonsurgical Treatment<br>Initial treatment of mild Achilles tendinitis involves rest, stretching exercises, and non-prescriptive medications to relieve pain and reduce inflammation. These medications include nonsteroidal anti-inflammatory drugs (NSAID) such as ibuprofen or naproxen. Relief of pain and swelling may be achieved with the application of ice for15 minutes at a time. Sleeping with the affected foot propped up on a pillow may also relieve swelling. Adequate time must be given to rest and recovery, meaning months or weeks, to prevent re-injury of the Achilles tendon. Most people make a full recovery and are able to return to their regular sports and exercise programs.<br><br><br>Surgical Treatment<br>If non-surgical treatment fails to cure the condition then surgery can be considered. This is more likely to be the case if the pain has been present for six months or more. The nature of the surgery depends if you have insertional, or non-insertional disease. In non-insertional tendonosis the damaged tendon is thinned and cleaned. The damage is then repaired. If there is extensive damage one of the tendons which moves your big toe (the flexor hallucis longus) may be used to reinforce the damaged Achilles tendon. In insertional tendonosis there is often rubbing of the tendon by a prominent part of the heel bone. This bone is removed. In removing the bone the attachment of the tendon to the bone may be weakened. In these cases the attachment of the tendon to the bone may need to be reinforced with sutures and bone anchors.<br><br>Prevention<br>A 2014 study looked at the effect of using foot orthotics on the Achilles tendon. The researchers found that running with foot orthotics resulted in a significant decrease in Achilles tendon load compared to running without orthotics. This study indicates that foot orthoses may act to reduce the incidence of chronic Achilles tendon pathologies in runners by reducing stress on the Achilles tendon1. Orthotics seem to reduce load on the Achilles tendon by reducing excessive pronation,
