Achilles tendonitis is an inflammation of the Achilles tendon. This inflammation is typically short-lived. Over time, if not resolved, the condition may progress to a degeneration of the tendon (Achilles tendonosis), in which the tendon loses its organized structure and is likely to develop microscopic tears. Sometimes the degeneration involves the site where the Achilles tendon attaches to the heel bone. In rare cases, chronic degeneration with or without pain may result in rupture of the tendon.
Achilles tendinitis is typically not related to a specific injury. The problem results from repetitive stress to the tendon. This often happens when we push our bodies to do too much, too soon, but other factors can make it more likely to develop tendinitis, including a bone spur that has developed where the tendon attaches to the heel bone, Sudden increase in the amount or intensity of exercise activity-for example, increasing the distance you run every day by a few miles without giving your body a chance to adjust to the new distance, Tight calf muscles, Having tight calf muscles and suddenly starting an aggressive exercise program can put extra stress on the Achilles tendon, Bone spur-Extra bone growth where the Achilles tendon attaches to the heel bone can rub against the tendon and cause pain.
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.
During an examination of the foot and ankle, you doctor will look for the following signs, Achilles tendon swelling or thickening. Bone spurs appearing at the lower part of the tendon at the back of the hell. Pain at the middle or lower area of the Achilles tendon. Limited range of motion of the foot and ankle, and a decreased ability to flex the foot. Your doctor may perform imaging tests, such as X-rays and MRI scans, to make a diagnosis of Achilles tendinitis. X-rays show images of the bones and can help the physician to determine if the Achilles tendon has become hardened, which indicated insertional Achilles tendinitis. MRI scans may not be necessary, but they are important guides if you are recommended to have surgical treatment. An MRI can show the severity of the damage and determine what kind of procedure would be best to address the condition.
With proper care for the area, the pain in the tendon should lessen over three weeks, but it should be noted that the healing of the area continues and doesn't even peak until at least six weeks following the initial injury. This is due to scar tissue formation, which initially acts like the glue to bond the tissue back together. Scar tissue will continue to form past six weeks in some cases and as long as a year in severe cases. After 6 months this condition is considered chronic and much more difficult to treat. The initial approach to treating Achilles tendonitis is to support and protect the tendons by bracing any areas of the tendon that are being pulled on during use. It is important to loosen up the tendon, lessen the pain, and minimize any inflammation.
In most surgeries, damaged tissue is cleaned out before surgeons make the necessary repairs. However, a new minimally-invasive surgery to repair a torn Achilles tendon actually uses the damaged tissue to help repair the tear. The percutaneous Achilles repair system, or PARS technique, enables surgeons to better repair a torn Achilles tendon through a smaller incision. This procedure was recently performed at Houston Methodist Hospital to treat an NFL cornerback, getting him back on field for this season.
If you're just getting started with your training, be sure to stretch after running, and start slowly, increasing your mileage by no more than 10% per week. Strengthen your calf muscles with exercises such as toe raises. Work low-impact cross-training activities, such as cycling and swimming, into your training.
