Achilles tendinosis (also known as Achilles tendinopathy) is a soreness and stiffness that comes on gradually and continues to worsen until treated. It is a common injury among middle and long distance runners. The severity of Achilles tendinosis can be broken down into four stages, each of which can be measured in terms of how the Achilles tendon feels during exercise, the amount of stiffness and creaking, and Achilles tendon?s soreness to the touch (the Achilles tendon pinch test). The four stages, or grades, are, No pain during exercise, but there is some discomfort in the morning when first getting out of bed. The stiffness and creaking go away after a few minutes and are fine the rest of the day. Lightly pinching the Achilles tendon with the forefinger and thumb in the morning or after exercise will probably indicate soreness. Pain during exercise or running, but performance is not affected. The stiffness and creaking continue to appear when first getting out of bed and continue to disappear shortly afterward. Lightly pinching the Achilles tendon with the forefinger and thumb in the morning or after exercise will indicate soreness. Pain during exercise or running that is detrimental to performance. The stiffness and creaking continue to appear when first getting out of bed, but may continue for some time and reappear at other points during the day. Lightly pinching the Achilles tendon with the forefinger and thumb in the morning or after exercise will indicate soreness. Hurts too much to exercise or run. The stiffness and creaking continue to appear when first getting out of bed, but may continue for most of the day. Lightly pinching the Achilles tendon with the forefinger and thumb at almost any time of day will indicate soreness.
When you place a large amount of stress on your Achilles tendon too quickly, it can become inflamed from tiny tears that occur during the activity. Achilles tendonitis is often a result of overtraining, or doing too much too soon. Excessive hill running can contribute to it. Flattening of the arch of your foot can place you at increased risk of developing Achilles tendonitis because of the extra stress placed on your Achilles tendon when walking or running.
Symptoms include pain in the heel and along the tendon when walking or running. The area may feel painful and stiff in the morning. The tendon may be painful to touch or move. The area may be swollen and warm. You may have trouble standing up on one toe.
During the physical exam, your doctor will gently press on the affected area to determine the location of pain, tenderness or swelling. He or she will also evaluate the flexibility, alignment, range of motion and reflexes of your foot and ankle. Your doctor may order one or more of the following tests to assess your condition, X-rays. While X-rays can't visualize soft tissues such as tendons, they may help rule out other conditions that can cause similar symptoms. Ultrasound. This device uses sound waves to visualize soft tissues like tendons. Ultrasound can also produce real-time images of the Achilles tendon in motion. Magnetic resonance imaging (MRI). Using radio waves and a very strong magnet, MRI machines can produce very detailed images of the Achilles tendon.
Initial treatment consists of medication and ice to relieve the pain, stretching and strengthening exercises, and modification of the activity that initially caused the problem. These all can be carried out at home, although referral to a physical therapist or athletic trainer for further evaluation and treatment may be helpful. Occasionally a walking boot or cast may be recommended to immobilize the tendon, allowing the inflammation to settle down. For less severe cases or after immobilization, a heel lift may be prescribed to reduce stress to the tendon. This may be followed by an elastic bandage wrap of the ankle and Achilles tendon. Orthotics (arch supports) may be prescribed or recommended by your physician. Surgery to remove the inflamed tendon lining or degenerated tendon tissue is rarely necessary and has shown less than predictable results.
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.
Maintaining strength and flexibility in the muscles of the calf will help reduce the risk of tendinitis. Overusing a weak or tight Achilles tendon makes you more likely to develop tendinitis.
