Achilles tendonitis is inflammation of the tendon, usually resulting from overuse associated with a change in playing surface, footwear or intensity of an activity. The Achilles tendon is surrounded by a connective tissue sheath (paratenon, or 'paratendon'), rather than a true synovial sheath. The paratenon stretches with movement, allowing maximum gliding action. Near the insertion of the tendon are two bursae - the subcutaneous calcaneal and the retrocalcaneal bursae.
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.
People with Achilles tendinitis may experience pain during and after exercising. Running and jumping activities become painful and difficult. Symptoms include stiffness and pain in the back of the ankle when pushing off the ball of the foot. For patients with chronic tendinitis (longer than six weeks), x-rays may reveal calcification (hardening of the tissue) in the tendon. Chronic tendinitis can result in a breakdown of the tendon, or tendinosis, which weakens the tendon and may cause a rupture.
When diagnosing Achilles tendinitis, a doctor will ask the patient a few questions about their symptoms and then perform a physical examination. To perform a physical exam on the Achilles tendon, the doctor will lightly touch around the back of the ankle and tendon to locate the source of the pain or inflammation. They will also test the foot and ankle to see if their range of motion and flexibility has been impaired. The doctor might also order an imaging test to be done on the tendon. This will aid in the elimination of other possible causes of pain and swelling, and may help the doctor assess the level of damage (if any) that has been done to the tendon. Types of imaging tests that could be used for diagnosing Achilles tendinitis are MRI (Magnetic resonance imaging), X-ray, Ultrasound.
Most cases of Achilles tendonitis can be treated at home. Here's what to do. Stop doing the activity that led to the injury. Avoid putting stress on your legs and feet, and give your tendon plenty of time to fully recover. Use the RICE formula. Don't exercise for a few days, or try an exercise that doesn't stress your feet, such as swimming. If necessary, your doctor may recommend that you use crutches or wear a walking boot to keep weight off your foot. Apply an ice pack wrapped in a towel or a cold compress to your tendon for 15 minutes or more after you exercise or if you feel pain in the tendon. Use tape or an athletic wrap to keep swelling down and help support and immobilize the tendon. Lie down and raise your foot above the level of your heart, and if possible, try to sleep with your foot elevated. This will help keep the swelling to a minimum. Take anti-inflammatory medications. Pain relievers like ibuprofen can help ease pain and reduce swelling in the affected area. Stretch and exercise your ankles and calf muscles while you recover. Keeping your muscles, tendons, and ligaments strong and flexible will aid in your recovery and help you keep from reinjuring your Achilles tendon. A doctor or a physical therapist can help you come up with a good exercise program. Try a pair of prescription orthotic inserts for your shoes if your doctor thinks it will help. Sometimes orthotics can be helpful. Talk to your doctor or someone trained in fitting orthotics to find out if they might work for you. Achilles tendon surgery is rarely needed. It's usually only done if the tendon breaks, and then only as a last resort after other methods of therapy have been tried. Most cases of Achilles tendonitis will get better on their own with rest and minor treatment.
Surgery can be done to remove hardened fibrous tissue and repair any small tendon tears as a result of repetitive use injuries. This approach can also be used to help prevent an Achilles tendon rupture. If your Achilles tendon has already ruptured or torn, Achilles tendon surgery can be used to reattach the ends of the torn tendon. This approach is more thorough and definitive compared to non surgical treatment options discussed above. Surgical reattachment of the tendon also minimizes the change of re-rupturing the Achilles tendon.
Suggestions to reduce your risk of Achilles tendonitis include, incorporate stretching into your warm-up and cool-down routines, maintain an adequate level of fitness for your sport, avoid dramatic increases in sports training, if you experience pain in your Achilles tendon, rest the area. Trying to ?work through? the pain will only make your injury worse, wear good quality supportive shoes appropriate to your sport. If there is foot deformity or flattening, obtain orthoses, avoid wearing high heels on a regular basis. Maintaining your foot in a ?tiptoe? position shortens your calf muscles and reduces the flexibility of your Achilles tendon. An inflexible Achilles tendon is more susceptible to injury, maintain a normal healthy weight.
