Overview Achilles tendon ruptures commonly occur in athletic individuals in their 30s and 40s while performing activities that require sudden acceleration or changes in direction (ex. basketball, tennis, etc.). Patients usually describe a sharp pain in their heel region almost as if they were ?struck in the back of the leg?. The diagnosis of an acute Achilles tendon rupture is made on clinical examination as x-rays will reveal the ankle bones to be normal. The Achilles is the largest and strongest tendon in the body. It is subject to 2-3 times body weight during normal walking so regaining normal Achilles tendon function is critical. Achilles tendon ruptures can be successfully treated non-operatively, or operatively, but they must be treated. Surgical treatment leads to a faster recovery and a lower rate of re-rupture. However, surgery can be associated with very serious complications such as an infection or wound healing problems. For this reason non-operative treatment may be preferable in many individuals, especially those patients with diabetes, vascular disease, and those who are long-term smokers. Causes An Achilles tendon injury might be caused by several factors. Overuse. Stepping up your level of physical activity too quickly. Wearing high heels, which increases the stress on the tendon. Problems with the feet, an Achilles tendon injury can result from flat feet, also known as fallen arches or overpronation. In this condition, the impact of a step causes the arch of your foot to collapse, stretching the muscles and tendons. Muscles or tendons in the leg that are too tight. Achilles tendon injuries are common in people who participate in the following sports. Running. Gymnastics. Dance. Football. Baseball. Softball. Basketball. Tennis. Volleyball. You are more likely to tear an Achilles tendon when you start moving suddenly. For instance, a sprinter might get one at the start of a race. The abrupt tensing of the muscle can be too much for the tendon to handle. Men older than age 30 are particularly prone to Achilles tendon injuries. Symptoms A classic sign of an Achilles tendon rupture is the feeling of being hit in the Achilles are. There is often a "pop" sound. There may be little pain, but the person can not lift up onto his toes while weight bearing. Diagnosis Diagnosis is made by clinical history; typically people say it feels like being kicked or shot behind the ankle. Upon examination a gap may be felt just above the heel unless swelling has filled the gap and the Simmonds' test (aka Thompson test) will be positive; squeezing the calf muscles of the affected side while the patient lies prone, face down, with his feet hanging loose results in no movement (no passive plantarflexion) of the foot, while movement is expected with an intact Achilles tendon and should be observable upon manipulation of the uninvolved calf. Walking will usually be severely impaired, as the patient will be unable to step off the ground using the injured leg. The patient will also be unable to stand up on the toes of that leg, and pointing the foot downward (plantarflexion) will be impaired. Pain may be severe, and swelling is common. Sometimes an ultrasound scan may be required to clarify or confirm the diagnosis. MRI can also be used to confirm the diagnosis. Non Surgical Treatment A physical therapist teaches you exercises to help improve movement and strength, and to decrease pain. Use support devices as directed. You may need crutches or a cane for support when you walk. These devices help decrease stress and pressure on your tendon. Your caregiver will tell you how much weight you can put on your leg. Ask for more information about how to use crutches or a cane correctly. Start activity as directed. Your caregiver will tell you when it is okay to walk and play sports. You may not be able to play sports for 6 months or longer. Ask when you can go back to work or school. Do not drive until your caregiver says it is okay. Surgical Treatment In general, for complete tear of the tendon, surgery is recommended. For partial tears, nonsurgical treatment is recommended. However, the selection of treatment depends on the patient, age, level of activity, and other risk factors. Surgery for Achilles tendon rupture is now routine and well established. Surgery is generally suggested for the young, healthy and active individuals. For athletes, surgery is often the first choice of treatment. The Achilles tendon can be repaired surgically by either a closed or open technique. With the open technique, an incision is made to allow for better visualization and approximation of the tendon. With the closed technique, the surgeon makes several small skin incisions through which the tendon is repaired. Irrespective of type of treatment, a short leg cast (plaster) is applied on the operated ankle after completion of the procedure. The advantages of a surgical approach includes a decreased risk of re-rupture rate (0%-5%) the majority of individuals can return to their original sporting activities (within a short time), and most regain their strength and endurance. Disadvantages of a surgical approach include hospital admission, wound complications (for example, skin sloughing, infection, sinus tract formation, sural nerve injury), higher costs, and hospital admission. Prevention Good flexibility of the calf muscles plays an essential role in the prevention of Achilles tendon injuries. It is also important to include balance and stability work as part of the training programme. This should include work for the deep-seated abdominal muscles and for the muscles that control the hip. This might at first appear odd, given the fact that the Achilles are a good distance from these areas, but developing strength and control in this area (core stability) can boost control at the knee and ankle joints. Training errors should be avoided. The volume, intensity and frequency of training should be monitored carefully, and gradually progressed, particularly when introducing new modes of training to the programme. Abrupt changes in training load are the primary cause of Achilles tendinopathy.
