Achilles tendinitis describes an inflammatory change of the Achilles tendon without a tear of the tendon. Achilles tendinitis may be acute or chronic. The onset of pain is usually unilateral but may be found bilaterally. Achilles tendinitis is common in the third or fourth decade of life in patients who are active with sports or in jobs that require physical labor. Pain is described at the insertion of the tendon in the heel bone or in the body of the tendon.
Achilles tendinitis is caused by repeated stress to the tendon, not a direct injury. Often times, this can happen from doing too much too soon and not giving your body enough time to rest or adjust to the increase in intensity or amount of exercise. Another contributing factor can be tight calf muscles. Having tight calf muscles and starting an activity can put added stress on the achilles tendon.
The Achilles tendon is a strong muscle and is not usually damaged by one specific injury. Tendinitis develops from repetitive stress, sudden increase or intensity of exercise activity, tight calf muscles, or a bone spur that rubs against the tendon. Common signs and symptoms of Achilles Tendinitis include, gradual onset of pain at the back of the ankle which may develop in several days up to several months to become bothersome. Heel pain during physical activities which may diminish after warming up in early stages, or become a constant problem if the problem becomes chronic. Stiffness at the back of the ankle in the morning. During inactivity, pain eases. Swelling or thickening of the Achilles tendon. Painful sensation if the Achilles tendon is palpated. If a pop is heard suddenly, then there is an increased chance that the Achilles tendon has been torn and immediate medical attention is needed.
X-rays are usually normal in patients with Achilles tendonitis, but are performed to evaluate for other possible conditions. Occasionally, an MRI is needed to evaluate a patient for tears within the tendon. If there is a thought of surgical treatment an MRI may be helpful for preoperative evaluation and planning.
Proper footwear with a strong and secure counter (the heel circumference) may help to encourage heeling of the tendon. A tendinitis will occasionally resolve on it?s own, with rest, ice, and gentle stretching. If symptoms persist for more than 2 weeks, consult your physician. Your physician may suggest physiotherapy and custom orthotics. Physiotherapy can suggest appropriate exercises and modalities to aid in the healing process. Custom orthotics can be very successful in treating the problem, as the original cause may be due to an improper alignment of the foot and heel. Re-aligning the foot to a neutral position may provide an optimal, biomechanically sound environment for healing to occur.
It is important to understand that surgery may not give you 100% functionality of your leg, but you should be able to return to most if not all of your pre-injury activities. These surgical procedures are often performed with very successful results. What truly makes a difference is your commitment to a doctor recommended rehabilitation program after surgery as there is always a possibility of re-injuring your tendon even after a surgical procedure. One complication of surgical repair for Achilles tendon tear is that skin can become thin at site of incision, and may have limited blood flow.
To prevent Achilles tendonitis or tendonosis from recurring after surgical or non-surgical treatment, the foot and ankle surgeon may recommend strengthening and stretching of the calf muscles through daily exercises. Wearing proper shoes for the foot type and activity is also important in preventing recurrence of the condition.
