Achilles tendonitis is a relatively common condition characterized by tissue damage and pain in the Achilles tendon. The muscle group at the back of the lower leg is commonly called the calf. The calf comprises of 2 major muscles, one of which originates from above the knee joint (gastrocnemius), the other of which originates from below the knee joint (soleus). Both of these muscles insert into the heel bone via the Achilles tendon. During contraction of the calf, tension is placed through the Achilles tendon. When this tension is excessive due to too much repetition or high force, damage to the tendon occurs. Achilles tendonitis is a condition whereby there is damage to the tendon with subsequent degeneration and inflammation. This may occur traumatically due to a high force going through the tendon beyond what it can withstand or, more commonly, due to gradual wear and tear associated with overuse.
Tight or tired calf muscles, which transfer too much of the force associated with running onto the Achilles tendon. Not stretching the calves properly or a rapid increase in intensity and frequency of sport training can make calf muscles fatigued. Activities which place a lot of stress on the achilles tendon, such as hill running and sprint training, can also cause Achilles Tendinitis. Runners who overpronate (roll too far inward on their feet during impact) are most susceptible to Achilles Tendinitis. Runners with flat feet are susceptible to Achilles Tendinitis because flat feet cause a 'wringing out' effect on the achilles tendon during running. High arched feet usually absorb less shock from the impact of running so that shock is transferred to the Achilles tendon. Use of inappropriate footwear when playing sport or running e.g., sandals, can also put an extra load on the Achilles tendon. Shoes are now available that have been designed for individual sports and provide cushioning to absorb the shock of impact and support for the foot during forceful movements. Training on hard surfaces e.g., concrete, also increases the risk of Achilles Tendinitis. Landing heavily or continuously on a hard surface can send a shock through the body which is partly absorbed by the Achilles tendon. A soft surface like grass turf helps to lessen the shock of the impact by absorbing some of the force of the feet landing heavily on the ground after a jump or during a running motion.
The primary symptom of Achilles tendon inflammation is pain in the back of the heel, which initially increases when exercise is begun and often lessens as exercise continues. A complete tear of the Achilles tendon typically occurs with a sudden forceful change in direction when running or playing tennis and is often accompanied by a sensation of having been struck in the back of the ankle and calf with an object such as a baseball bat.
Confirming Achilles tendonitis may involve imaging tests. X-rays provide images of the bones of the foot pain gout (jacalyngretz.wordpress.com) and leg. Magnetic resonance imaging (MRI) is useful for detecting ruptures and degeneration of tissue. Ultrasound shows tendon movement, related damage, and inflammation.
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.
When the tendon tears or ruptures the variety of surgical techniques are available to repair the damage and restore the tendons function. Recent research that is done at Emory University Department of orthopedics have perfected the repair of the Achilles tendon. The procedure is generally involves making an incision in the back of your leg and stitching the torn tendon together using a technique developed and tested by Dr. Labib. Depending on the condition of the torn tissue the repair may be reinforced with other tendons.
While it may not be possible to prevent Achilles tendinitis, you can take measures to reduce your risk. Increase your activity level gradually. If you're just beginning an exercise regimen, start slowly and gradually increase the duration and intensity of the training. Take it easy. Avoid activities that place excessive stress on your tendons, such as hill running. If you participate in a strenuous activity, warm up first by exercising at a slower pace. If you notice pain during a particular exercise, stop and rest. Choose your shoes carefully. The shoes you wear while exercising should provide adequate cushioning for your heel and should have a firm arch support to help reduce the tension in the Achilles tendon. Replace your worn-out shoes. If your shoes are in good condition but don't support your feet, try arch supports in both shoes. Stretch daily. Take the time to stretch your calf muscles and Achilles tendon in the morning, before exercise and after exercise to maintain flexibility. This is especially important to avoid a recurrence of Achilles tendinitis. Strengthen your calf muscles. Strong calf muscles enable the calf and Achilles tendon to better handle the stresses they encounter with activity and exercise. Cross-train. Alternate high-impact activities, such as running and jumping, with low-impact activities, such as cycling and swimming.
