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.
There are hundreds of tendons scattered throughout our body, but it tends to be a small handful of specific tendons that cause problems. These tendons usually have an area of poor blood supply that leads to tissue damage and poor healing response. This area of a tendon that is prone to injury is called a "watershed zone," an area when the blood supply to the tendon is weakest. In these watershed zones, they body has a hard time delivering oxygen and nutrients necessary for tendon healing, that's why we see common tendon problems in the same parts of the body. Tendonitis is most often an overuse injury. Often people begin a new activity or exercise that causes the tendon to become irritated. Tendon problems are most common in the 40-60 year old age range. Tendons are not as elastic and forgiving as in younger individuals, yet bodies are still exerting with the same force. Occasionally, there is an anatomical cause for tendonitis. If the tendon does not have a smooth path to glide along, it will be more likely to become irritated and inflamed. In these unusual situations, surgical treatment may be necessary to realign the tendon.
Dull or sharp pain anywhere along the back of the tendon, but usually close to the heel. limited ankle flexibility redness or heat over the painful area a nodule (a lumpy build-up of scar tissue) that can be felt on the tendon a cracking sound (scar tissue rubbing against tendon) with ankle movement.
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.
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.
Surgical treatment for tendons that fail to respond to conservative treatment can involve several procedures, all of which are designed to irritate the tendon and initiate a chemically mediated healing response. These procedures range from more simple procedures such as percutaneous tenotomy61 to open procedures and removal of tendon pathology. Percutaneous tenotomy resulted in 75% of patients reporting good or excellent results after 18 months. Open surgery for Achilles tendinopathy has shown that the outcomes are better for those tendons without a focal lesion compared with those with a focal area of tendinopathy.62 At 7 months after surgery, 67% had returned to physical activity, 88% from the no-lesion group and 50% from the group with a focal lesion.
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.
