The Achilles tendon attaches the calf muscle to the heel bone. Achilles tendonitis is a repetitive strain (overuse) injury involving lower leg muscles and tendons at the point where they attach to the bone, resulting in pain at the back of the ankle. Chronic overuse can lead to small tears within the tendon causing long-term weakening, making the tendon susceptible to rupture, which could result in a need for surgery.
Tendons are the tough fibres that connect muscle to bone. Most tendon injuries occur near joints, such as the shoulder, elbow, knee, and ankle. A tendon injury may seem to happen suddenly, but usually it is the result of many tiny tears to the tendon that have happened over time. Health professionals may use different terms to describe a tendon injury. You may hear, Tendonitis (or Tendinitis): This actually means “inflammation of the tendon,” but inflammation is rarely the cause of your tendon pain.
Achilles tendinitis symptoms present as mild to severe pain or swelling near the ankle. The pain may lead to weakness and decreased mobility, symptoms that increase gradually while walking or running. Over time, the pain worsens, and stiffness in the tendon may be noted in the morning. Mild activity may provide relief. Physical exam may reveal an audible cracking sound when the Achilles tendon is palpated. The lower leg may exhibit weakness. A ruptured or torn Achilles tendon is severely painful and warrants immediate medical attention. The signs of a ruptured or torn Achilles tendon include. Acute, excruciating pain. Impaired mobility, unable to point the foot downward or walk on the toes. Weight bearing or walking on the affected side is not possible.
A doctor examines the patient, checking for pain and swelling along the posterior of the leg. The doctor interviews the patient regarding the onset, history, and description of pain and weakness. The muscles, tissues, bones, and blood vessels may be evaluated with imaging studies, such as X-ray, ultrasound, or MRI.
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 is considered when non-operative measures fail. Patient compliance and postoperative management is an important aspect of the operative management to prevent ankle stiffness or recurrence of the symptoms. Surgery usually requires a removal of the damaged tissue (debridement) and meticulous repair of the tendon. Post-operative immobilization is required, followed by gradual range of motion and strengthening exercises start. It may require 6 months for the full recovery. Some known complication are recurrence, stiffness of the ankle and deep vein thrombosis.
Wear shoes that fit correctly and support your feet: Replace your running or exercise shoes before the padding or shock absorption wears out. Shock absorption greatly decreases as the treads on the bottoms or sides of your shoes begin to wear down. You may need running shoes that give your foot more heel or arch support. You may need shoe inserts to keep your foot from rolling inward. Stretch before you exercise: Always warm up your muscles and stretch gently before you exercise. Do cool down exercises when you are finished. This will loosen your muscles and decrease stress on your Achilles tendon. Exercise the right way: If your tendinitis is caused by the way that you exercise, ask a trainer, coach, or your caregiver for help. They can teach you ways to train or exercise to help prevent Achilles tendinitis. Do not run or exercise on uneven or hard surfaces. Instead, run on softer surfaces such as treadmills, rubber tracks, grass, or evenly packed dirt tracks.
