Achilles tendinitis is very common among running athletes. The calf muscles attach to the calcaneus via the Achilles tendon. During running, the calf muscles help with the lift-off phase of gait. Repetitive forces from running combined with insufficient recovery time can initially cause inflammation in the tendon paratenon (fatty areolar tissue that surrounds the tendon). A complete tear of the Achilles tendon is a serious injury, usually resulting from sudden, forceful stress. Tendon tears can occur with minimal exertion in people who have taken fluoroquinolone antibiotics.
Achilles tendinitis is usually caused by straining the Achilles tendon through intense activity or a sudden increase in exercise. Individuals who play basketball often develop Achilles tendinitis as a result of pivoting, jumping, and running. These repetitive movements put pressure on the tendon and can gradually wear it down over time. Increasing the intensity of your workouts may also lead to the development of Achilles tendinitis. This is commonly seen in long distance runners who do quite a bit of uphill running. Similarly, if you start exercising more frequently you may also develop the condition due to overuse of the tendon. Not stretching properly before exercise can also make the tendon more prone to injury. Achilles tendinitis is also common in individuals whose feet have a flattened arch, as this places more stress on the tendon. The condition can also be triggered by arthritis, as joint pain can cause one to compensate by putting more pressure on the Achilles tendon.
There will be a gradual onset of achilles tendon pain over a period of weeks, or even months. The pain will come on during exercise and is constant throughout the training session. Pain will be felt in the achilles tendon when walking especially up hill or up stairs. This is because the achilles is having to stretch further than normal. There is likely to be stiffness in the Achilles tendon especially in the morning or after a long period of rest. This is thought to be due to adhesions between the tendon sheath and the tendon itself. Nodules or lumps may be found in the achilles tendon, particularly 2-4cm above the heel and the skin will appear red. Pain and tenderness will be felt when pressing in on the achilles tendon which is likely to appear thickened or swollen. A creaking sensation may be felt when press the fingers into the sides of the tendon and moving the ankle.This is known as crepitus.
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 depends on severity of pain. The most effective long-term treatment for Achilles tendinitis/tendinopathy is physical therapy, particularly therapy that focuses on eccentric muscle/tendon strengthening. Calf and Achilles stretching are also an important part of the treatment. In severe cases, treatment may begin with a period of rest and immobilization in order to calm down the tendon before physical therapy is initiated. Anti-inflammatories may be prescribed. Avoiding activities that aggravate the Achilles tendon will help the healing process. Improvement and resolution of symptoms can take months. Exercise might be the cause of Achilles tendonitis, but it can also help prevent it and aid in recovery. Healing will occur more quickly if there is no pressure on the injured tendon, and if the foot is at least partially immobilized.
Surgery is considered the last resort. It is only recommended if all other treatment options have failed after at least six months. In this situation, badly damaged portions of the tendon may be removed. If the tendon has ruptured, surgery is necessary to re-attach the tendon. Rehabilitation, including stretching and strength exercises, is started soon after the surgery. In most cases, normal activities can be resumed after about 10 weeks. Return to competitive sport for some people may be delayed for about three to six months.
Appropriately warm up and stretch before practice or competition. Allow time for adequate rest and recovery between practices and competition. Maintain appropriate conditioning, Ankle and leg flexibility, Muscle strength and endurance, Cardiovascular fitness. Use proper technique. To help prevent recurrence, taping, protective strapping, or an adhesive bandage may be recommended for several weeks after healing is complete.
