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.
Achilles tendonitis is aggravated by activities that repeatedly stress the tendon, causing inflammation. In some cases even prolonged periods of standing can cause symptoms. In many people who have developed achilles tendonitis, chronic shortening of the gastroc-soleus muscle complex is the reason that home remedies and anti-inflammatory medications fail. In these instances the muscle itself becomes shortened and creates a constant stress at the tendon?s attachment. Like a green branch that is slowly bent, eventually it begins to breakdown. Over a prolonged period the tendon becomes inflamed, and in the worst cases, appears swollen and thickened. In certain circumstances attempts to heal have failed and the body?s inability to heal the tissue results in degenerative changes known as achilles tendonosis. Anti-inflammatory medication, stretching and ice may only provide temporary relief, because they address the inflammation but not the root cause.
The pain associated with Achilles tendonitis can come on gradually or be caused by some type of leg or foot trauma. The pain can be a shooting, burning, or a dull ache. You can experience the pain at either the insertion point on the back of the heel or upwards on the Achilles tendon within a few inches. Swelling is also common along the area with the pain. The onset of discomfort at the insertion can cause a bump to occur called a Haglund's deformities or Pump bump. This can be inflammation in the bursa sac that surrounds the insertion of the Achilles tendon, scar tissue from continuous tares of the tendon, or even some calcium buildup. In this situation the wearing of closed back shoes could irritate the bump. In the event of a rupture, which is rare, the foot will not be able to go through the final stage of push off causing instability. Finally, you may experience discomfort, even cramping in the calf muscle.
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.
There is insufficient evidence from randomised controlled trials to determine which method of treatment is the most appropriate for the treatment of acute or chronic Achilles tendonitis. The patient should abstain from aggravating activities, but with a minimum of rest in order to preserve overall fitness. Possible treatments are non-steroidal anti-inflammatory drugs (NSAIDs), ice, rest, increased warm-up/stretching exercises, physiotherapy and heel lifts (orthotic devices - used on both sides to prevent a gait imbalance). Other treatments evaluated in a Cochrane review were heparin, steroid injections, glycosaminoglycan sulfate, Actovegin?, and topical laser treatment. There was no clear evidence of benefit from these. Casting is an option for resistant Achilles tendonitis. Drugs - analgesics and NSAIDs. Surgery is sometimes used for resistant Achilles tendonitis, but usually as a last resort. Other recently reported treatments include continuing sporting activity in conjunction with rehabilitation, low-energy shock wave therapy and topical glyceryl trinitrate .
Surgery for an Achilles tendon rupture can be done with a single large incision, which is called open surgery. Or it can be done with several small incisions. This is called percutaneous surgery. The differences in age and activity levels of people who get surgery can make it hard to know if Achilles tendon surgery is effective. The success of your surgery can depend on, your surgeon's experience. The type of surgery you have. How damaged the tendon is. How soon after rupture the surgery is done. How soon you start your rehab program after surgery. How well you follow your rehab program. Talk to your surgeon about his or her surgical experience. Ask about his or her success rate with the technique that would best treat your condition.
Maintaining strength and flexibility in the muscles of the calf will help reduce the risk of tendinitis. Overusing a weak or tight Achilles tendon makes you more likely to develop tendinitis.
