Achilles tendinitis is an inflammation (swelling) of the tendon, which usually occurs as a result of overuse injury. Basketball players are the most susceptible to Achilles tendinitis because of the frequent jumping. Any activity requiring a constant pushing off the foot, such as running or dancing, may result in swelling of the tendon.
Tight or tired calf muscles, which transfer too much of the force associated with running onto the Achilles tendon. Not stretching the calves properly or a rapid increase in intensity and frequency of sport training can make calf muscles fatigued. Activities which place a lot of stress on the achilles tendon, such as hill running and sprint training, can also cause Achilles Tendinitis. Runners who overpronate (roll too far inward on their feet during impact) are most susceptible to Achilles Tendinitis. Runners with flat feet are susceptible to Achilles Tendinitis because flat feet cause a ‘wringing out’ effect on the achilles tendon during running. High arched feet usually absorb less shock from the impact of running so that shock is transferred to the Achilles tendon. Use of inappropriate footwear when playing sport or running e.g., sandals, can also put an extra load on the Achilles tendon. Shoes are now available that have been designed for individual sports and provide cushioning to absorb the shock of impact and support for the foot during forceful movements. Training on hard surfaces e.g., concrete, also increases the risk of Achilles Tendinitis. Landing heavily or continuously on a hard surface can send a shock through the body which is partly absorbed by the Achilles tendon. A soft surface like grass turf helps to lessen the shock of the impact by absorbing some of the force of the feet landing heavily on the ground after a jump or during a running motion.
In most cases, symptoms of Achilles tendonitis, also sometimes called Achilles tendinitis, develop gradually. Pain may be mild at first and worsen with continued activity. Repeated or continued stress on the Achilles tendon increases inflammation and may cause it to rupture. Partial or complete rupture results in traumatic damage and severe pain, making walking virtually impossible and requiring a long recovery period. Patients with tendinosis may experience a sensation of fullness in the back of the lower leg or develop a hard knot of tissue (nodule).
Laboratory studies usually are not necessary in evaluating and diagnosing an Achilles tendon rupture or injury, although evaluation may help to rule out some of the other possibilities in the differential diagnosis. Imaging studies. Plain radiography: Radiographs are more useful for ruling out other injuries than for ruling in Achilles tendon ruptures. Ultrasonography: Ultrasonography of the leg and thigh can help to evaluate the possibility of deep venous thrombosis and also can be used to rule out a Baker cyst; in experienced hands, ultrasonography can identify a ruptured Achilles tendon or the signs of tendinosis. Magnetic resonance imaging (MRI): MRI can facilitate definitive diagnosis of a disrupted tendon and can be used to distinguish between paratenonitis, tendinosis, and bursitis.
The best treatment for Achilles tendonitis is preventative, stretching and warming up properly before starting an activity. Proper rest, accompanied by stretching and icing to reduce swelling, can help to heal an overworked Achilles tendon. Placing an adequate heel lift in both shoes will allow the heel to have contact with the ground without placing stress on the Achilles tendon. Wear a tie shoe that is stiff soled and has a wide base, then add an over-the-counter or custom foot orthosis inside the shoe to prevent the twisting motion of the Achilles tendon due to over pronation. In the event that the tendon is unable to heal due to your life style or activity, you may have to be put in a walking cast for a short period to give it a chance to heal. You need to have the doctor, physical therapist, or come in to our facility to check for a leg length difference due to the walking cast being higher. This is to prevent any discomfort to the hips. After the tendon has healed and before the foot is taken out of the walking cast, range of motion at the ankle must be tested and if the foot is not allowed to properly bend upwards 15 degrees then the tightness in the calf will cause the foot to over pronate and reinjure. A stretching program will be needed to loosen up the calf muscle before much weight bearing is done without the cast. The stretching program can be found at the menu for feet hurt. If necessary a heel lift can be put in both shoes to help take the stress off the tendon. Should the tightness of the calves be the primary cause for the Achilles tendon damage and stretching has not loosen the Achilles tendon sufficiently, then discussion with your doctor for a calf release may have to be considered.
The type of surgery you will have depends on the type of injury you are faced with. The longer you have waited to have surgery will also be a factor that determines what type of surgery is needed. With acute (recent) tearing the separation in your Achilles tendon is likely to be very minimal. If you have an acute tear you may qualify for less invasive surgery (such as a mini-open procedure). Surgeons will always choose a shorter, less invasive procedure if it is possible to do so. Most surgeons know that a less complicated procedure will have less trauma to the tendon and a much quicker rate of recovery after the surgery.
Warm up slowly by running at least one minute per mile slower than your usual pace for the first mile. Running backwards during your first mile is also a very effective way to warm up the Achilles, because doing so produces a gentle eccentric load that acts to strengthen the tendon. Runners should also avoid making sudden changes in mileage, and they should be particularly careful when wearing racing flats, as these shoes produce very rapid rates of pronation that increase the risk of Achilles tendon injury. If you have a tendency to be stiff, spend extra time stretching. If you?re overly flexible, perform eccentric load exercises preventively. Lastly, it is always important to control biomechanical alignment issues, either with proper running shoes and if necessary, stock or custom orthotics.
