A torn or ruptured Achilles tendon is simply no fun at all. This essential cord of strong, fibrous material attaches the heel bone to the calf muscles and is used in just about every movement, from walking and running to jumping and standing on your tip-toes. It also helps bend the foot downwards at the ankle. As the strongest tendon in the body, the Achilles can withstand a force of about 1,000 pounds. About 7 out of every 100,000 people will suffer from a ruptured Achilles at some point in time, with over 80% of these injuries occurring during a recreational sports activity. Athletes have a 24% chance of tearing their Achilles, but competitive runners have a 40 to 50% chance of Achilles tendon rupture during their lifetime.
The tendon is susceptible to injury and can rupture during vigorous activities such as running and jumping. Rupture can also occur as a result of gradual wear. After becoming chronically weakened, it can rupture during non-stress activities like walking.
Symptoms of an Achilles tendon rupture include sensation that someone or something has hit the back of the calf muscle, sudden pain, pain when walking, weakness in the leg, which is particularly noticeable when trying to push off while walking and there is not sufficient strength to do so.
In diagnosing an Achilles tendon rupture, the foot and ankle surgeon will ask questions about how and when the injury occurred and whether the patient has previously injured the tendon or experienced similar symptoms. The surgeon will examine the foot and ankle, feeling for a defect in the tendon that suggests a tear. Range of motion and muscle strength will be evaluated and compared to the uninjured foot and ankle. If the Achilles tendon is ruptured, the patient will have less strength in pushing down (as on a gas pedal) and will have difficulty rising on the toes. The diagnosis of an Achilles tendon rupture is typically straightforward and can be made through this type of examination. In some cases, however, the surgeon may order an MRI or other advanced imaging tests.
Non Surgical Treatment
Treatment of a ruptured Achilles tendon is usually conservative (non-operative) in a Controlled Motion Ankle (CAM) Boot or it may require surgery. The current consensus based on research is to treat them conservatively since the functional outcome and chance of re-rupture is similar (7% to 15%) using both approaches but surgical intervention has a higher risk of infection. Achilles tendon surgery is usually considered if your Achilles has re-ruptured or there is delay of two weeks between the rupture and the diagnosis and commencement of conservative bracing and treatment.
Surgery offers important potential benefits. Besides decreasing the likelihood of re-rupturing the Achilles tendon, surgery often increases the patient?s push-off strength and improves muscle function and movement of the ankle. Various surgical techniques are available to repair the rupture. The surgeon will select the procedure best suited to the patient. Following surgery, the foot and ankle are initially immobilized in a cast or walking boot. The surgeon will determine when the patient can begin weightbearing. Complications such as incision-healing difficulties, re-rupture of the tendon, or nerve pain can arise after surgery. Whether an Achilles tendon rupture is treated surgically or non-surgically, physical therapy is an important component of the healing process. Physical therapy involves exercises that strengthen the muscles and improve the range of motion of the foot and ankle.
The best treatment of Achilles tendonitis is prevention. Stretching the Achilles tendon before exercise, even at the start of the day, will help to maintain ankle flexibility. Problems with foot mechanics can also lead to Achilles tendonitis. This can often be treated with devices inserted into the shoes such as heel cups, arch supports, and custom orthotics.
