The Achilles' tendon is located in the leg just behind and above the heel. As the connection between the heel and calf muscle, its function is to allow the bending of the foot downwards. Generally if there is a tear to the Achilles' tendon it will be known as a rupture. This can be a partial tear or a complete tear, although partial tears are much rarer.
An Achilles tendon rupture is often caused by overstretching the tendon. This typically occurs during intense physical activity, such as running or playing basketball. Pushing off from the foot while the knee is straight, pivoting, jumping, and running are all movements that can overstretch the Achilles tendon and cause it to rupture. A rupture can also occur as the result of trauma that causes an over-stretching of the tendon, such as suddenly tripping or falling from a significant height. The Achilles tendon is particularly susceptible to injury if it is already weak. Therefore, individuals who have a history of tendinitis or tendinosis are more prone to a tendon rupture. Similarly, individuals who have arthritis and overcompensate for their joint pain by putting more stress on the Achilles tendon may also be more susceptible to an Achilles tendon rupture.
Many people say that a ruptured Achilles feels like ?being shot in the heel?, if you can imagine how enjoyable that feels. You may hear a snap sound or feel a sudden sharp pain when the tendon tears. After a few moments, the pain settles and the back of the lower leg aches. You can walk and bear weight, but you may find it difficult to point the foot downward or push off the ground on the affected side. You will be unable to stand on tiptoe. Bruising and swelling are likely, and persistent pain will be present. Similar symptoms may be caused by an inflamed Achilles tendon (Achilles tendonitis), a torn calf muscle, arthritis of the ankle, or deep vein thrombosis in the calf, so an MRI or ultrasound scan will likely be used to diagnose your condition.
To diagnose an Achilles tendon injury, your health care provider will give you a thorough physical exam. He or she may want to see you walk or run to look for problems that might have contributed to your Achilles tendon injury.
Non Surgical Treatment
Once a diagnosis of Achilles tendon rupture has been confirmed, a referral to an orthopaedic specialist for treatment will be recommended. Treatment for an Achilles tendon rupture aims to facilitate the torn ends of the tendon healing back together again. Treatment may be non-surgical (conservative) or surgical. Factors such as the site and extent of the rupture, the time since the rupture occurred and the preferences of the specialist and patient will be considered when deciding which treatment will be undertaken. Some cases of rupture that have not responded well to non-surgical treatment may require surgery at a later stage. The doctor will immobilise the ankle in a cast or a special hinged splint (known as a ?moon boot?) with the foot in a toes-pointed position. The cast or splint will stay in place for 6 - 8 weeks. The cast will be checked and may be changed during this time.
The best treatment for a ruptured Achilles tendon in an active individual is typically surgery. While an Achilles rupture can sometimes be treated with a cast, splint, brace, or other device that will keep your lower leg from moving, surgery provides less chance that the tendon will rupture again and offers more strength and a shorter recovery period. Surgery may be delayed for a period of a week after the rupture, to let the swelling go down. There are two types of surgery to repair a ruptured Achilles tendon and both involve the surgeon sewing the tendon back together through the incision. Open surgery, the surgeon makes a single large incision in the back of the leg. Percutaneous surgery, the surgeon makes a number of small incisions rather than one large incision. Depending on the condition of the torn tissue, the repair may be reinforced with other tendons.
