Achilles tendonitis is inflammation and tendonosis is degeneration and irregular healing of the achilles tendon. The achilles tendon is the large tendon located in the back of the leg that inserts into the heel. The pain caused by achilles tendonitis/osis can develop gradually without a history of trauma. The pain can be a shooting pain, burning pain, or even an extremely piercing pain. Achilles tendonitis/osis should not be left untreated due to the danger that the tendon can become weak and rupture requiring surgery.
Sometimes Achilles Tendinitis is a result of sudden trauma, as you might encounter from playing sports, but you can also have Achilles tendon pain as a result of small, unnoticed, day-to-day irritations that inflame the tendon over time by a cumulative effect. In those with no history of trauma, Achilles Tendonitis is sometimes associated simply with long periods of standing. There are several factors that can cause the gradual development of Achilles Tendinitis. Improper shoe selection, particularly using high heels over many years, increases your odds of developing the condition. This is because high-heeled shoes cause your calf muscles to contract, leaving the tendon with a lot less slack in it. Inadequate stretching before engaging in athletic or other physically-demanding activities also predisposes you to develop the problem. This is especially true in "weekend athletes", individuals who tend to partake in excessive physical activities on an intermittent basis. Biomechanical abnormalities like excessive pronation (too much flattening of the arch) also tends to cause this condition. And it is much more common individuals with equinus. It is more common in the middle-aged, the out-of-shape, smokers, and in those who use steroids. Men get the condition more frequently than women. Those involved in jumping and high-impact sports are particularly vulnerable.
In most cases, symptoms of Achilles tendonitis, also sometimes called Achilles tendinitis, develop gradually. Pain may be mild at first and worsen with continued activity. Repeated or continued stress on the Achilles tendon increases inflammation and may cause it to rupture. Partial or complete rupture results in traumatic damage and severe pain, making walking virtually impossible and requiring a long recovery period. Patients with tendinosis may experience a sensation of fullness in the back of the lower leg or develop a hard knot of tissue (nodule).
A podiatrist can usually make the diagnosis by clinical history and physical examination alone. Pain with touching or stretching the tendon is typical. There may also be a visible swelling to the tendon. The patient frequently has difficulty plantarflexing (pushing down the ball of the foot and toes, like one would press on a gas pedal), particularly against resistance. In most cases X-rays don't show much, as they tend to show bone more than soft tissues. But X-rays may show associated degeneration of the heel bone that is common with Achilles Tendon problems. For example, heel spurs, calcification within the tendon, avulsion fractures, periostitis (a bruising of the outer covering of the bone) may all be seen on X-ray. In cases where we are uncertain as to the extent of the damage to the tendon, though, an MRI scan may be necessary, which images the soft tissues better than X-rays. When the tendon is simply inflamed and not severely damaged, the problem may or may not be visible on MRI. It depends upon the severity of the condition.
Tendon inflammation should initially be treated with ice, gentle calf muscle stretching, and use of NSAIDs. A heel lift can be placed in the shoes to take tension off the tendon. Athletes should be instructed to avoid uphill and downhill running until the tendon is not painful and to engage in cross-training aerobic conditioning. Complete tears of the Achilles tendon usually require surgical repair.
Achilles tendon repair surgery is often used to repair a ruptured or torn Achilles tendon, the strong fibrous cord that connects the two large muscles in the back of your calf to your heel bone. These muscles (the gastrocnemius and the soleus) create the power needed to push off with your foot or rise up on your toes. Achilles tendon ruptures are quite common. Most happen during recreational activities that require sudden bursts of muscle power in the legs. Often a torn Achilles tendon can be diagnosed with a physical examination. If swelling is present, the orthopaedist may delay the Achilles tendon surgery until it subsides.
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.
