Achilles tendinitis is an overuse injury of the Achilles tendon, the band of tissue that connects calf muscles at the back of the lower leg to your heel bone. Achilles tendinitis most commonly occurs in runners who have suddenly increased the intensity or duration of their runs. It’s also common in middle-aged people who play sports, such as tennis or basketball, only on the weekends. Most cases of Achilles tendinitis can be treated with relatively simple, at-home care under your doctor’s supervision. Self-care strategies are usually necessary to prevent recurring episodes. More-serious cases of Achilles tendinitis can lead to tendon tears (ruptures) that may require surgical repair.
Most common in middle-aged men. Conditions affecting the foot structure (such as fallen arches). Running on uneven, hilly ground, or in poor quality shoes. Diabetes. High blood pressure. Certain antibiotics. ?Weekend Warriors?. Recent increase in the intensity of an exercise program. While Achilles tendinitis can flare up with any overuse or strain of the Achilles tendon, it most often affects middle-aged men, especially if they are ?weekend warriors? who are relatively sedentary during the week, then decide to play basketball or football on Saturday. Those with flat feet or other structural conditions affecting their feet tend to put excess strain on the Achilles tendon, increasing their chances of developing Achilles tendinitis or even rupturing the tendon. If you are a runner, be sure to only run in quality running shoes that are supportive and well cushioned, and to be mindful of the surface you?re running on. Uneven surfaces and especially hilly terrain put additional strain on your Achilles tendon and can lead to the condition.
Patients with an Achilles tendon rupture frequently present with complaints of a sudden snap in the lower calf associated with acute, severe pain. The patient reports feeling like he or she has been shot, kicked, or cut in the back of the leg, which may result in an inability to ambulate further. A patient with Achilles tendon rupture will be unable to stand on his or her toes on the affected side. Tendinosis is often pain free. Typically, the only sign of the condition may be a palpable intratendinous nodule that accompanies the tendon as the ankle is placed through its range of motion (ROM). Patients with paratenonitis typically present with warmth, swelling, and diffuse tenderness localized 2-6 cm proximal to the tendon’s insertion. Paratenonitis with tendinosis. This is diagnosed in patients with activity-related pain, as well as swelling of the tendon sheath and tendon nodularity.
The doctor will perform a physical exam. The doctor will look for tenderness along the tendon and pain in the area of the tendon when you stand on your toes. X-rays can help diagnose bone problems. An MRI scan may be done if your doctor is thinking about surgery or is worried about the tear in the Achilles tendon.
The main treatments for Achilles tendinitis do not involve surgery. It is important to remember that it may take at least 2 to 3 months for the pain to go away. Try putting ice over the Achilles tendon for 15 to 20 minutes, two to three times per day. Remove the ice if the area gets numb. Changes in activity may help manage the symptoms. Decrease or stop any activity that causes you pain. Run or walk on smoother and softer surfaces. Switch to biking, swimming, or other activities that put less stress on the Achilles tendon. Your health care provider or physical therapist can show you stretching exercises for the Achilles tendon. They may also suggest the following changes in your footwear, a brace or boot or cast to keep the heel and tendon still and allow the swelling to go down, heel lifts placed in the shoe under the heel, shoes that are softer in the areas over and under the heel cushion. Nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin and ibuprofen can help with pain or swelling. Talk with your health care provider. If these treatments do not improve symptoms, you may need surgery to remove inflamed tissue and abnormal areas of the tendon. Surgery also can be used to remove the bone spur that is irritating the tendon. Extracorporeal shock wave therapy (ESWT) may be an alternative to surgery for people who have not responded to other treatments. This treatment uses low-dose sound waves.
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.
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.
