Achilles tendonitis is an inflammation of the Achilles tendon. This inflammation is typically short-lived. Over time, if not resolved, the condition may progress to a degeneration of the tendon (Achilles tendonosis), in which the tendon loses its organized structure and is likely to develop microscopic tears. Sometimes the degeneration involves the site where the Achilles tendon attaches to the heel bone. In rare cases, chronic degeneration with or without pain may result in rupture 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.
Symptoms include pain in the heel and along the tendon when walking or running. The area may feel painful and stiff in the morning. The tendon may be painful to touch or move. The area may be swollen and warm. You may have trouble standing up on one toe.
There is enlargement and warmth of the tendon 1 to 4 inches above its heel insertion. Pain and sometimes a scratching feeling may be created by gently squeezing the tendon between the thumb and forefinger during ankle motion. There may be weakness in push-off strength with walking. Magnetic resonance imaging (MRI) can define the extent of degeneration, the degree to which the tendon sheath is involved and the presence of other problems in this area, but the diagnosis is mostly clinical.
NSAIDS like ibuprofen are often prescribed to help manage the pain and inflammation. Steroids are often recommended when patients do not respond to NSAID treatment. They are often most effective when injected directly into the inflamed and swollen area. Physiotherapy is a great way to stretch and strengthen the Achilles tendon. A good physical therapist will also teach the patient techniques which give better foot support during exercise (taping, wrapping, etc?). Orthotics, assistive devices and insoles can be used to cushion and cradle the arch of the foot during the healing process. Shock Wave Therapy. This is the newest form of treatment and uses concentrated sound waves to stimulate healing in the affected area. This form of treatment is reserved for heel pain that is unresponsive to other forms of treatment.
Achilles tendon repair surgery is often used to repair a ruptured or torn Achilles tendon, the strong fibrous cord that connects the two large muscles in the back of your calf to your heel bone. These muscles (the gastrocnemius and the soleus) create the power needed to push off with your foot or rise up on your toes. Achilles tendon ruptures are quite common. Most happen during recreational activities that require sudden bursts of muscle power in the legs. Often a torn Achilles tendon can be diagnosed with a physical examination. If swelling is present, the orthopaedist may delay the Achilles tendon surgery until it subsides.
Although Achilles tendinitis cannot be completely prevented, the risk of developing it can be lowered. Being aware of the possible causes does help, but the risk can be greatly reduced by taking the following precautions. Getting a variety of exercise - alternating between high-impact exercises (e.g. running) and low-impact exercise (e.g. swimming) can help, as it means there are days when the Achilles tendon is under less tension. Limit certain exercises - doing too much hill running, for example, can put excessive strain on the Achilles tendon. Wearing the correct shoes and replacing them when worn - making sure they support the arch and protect the heel will create less tension in the tendon. Using arch supports inside the shoe, if the shoe is in good condition but doesn't provide the required arch support this is a cheaper (and possibly more effective) alternative to replacing the shoe completely. Stretching, doing this before and after exercising helps to keep the Achilles tendon flexible, which means less chance of tendinitis developing. There is no harm in stretching every day (even on days of rest), as this will only further improve flexibility. Gradually increasing the intensity of a workout - Achilles tendinitis can occur when the tendon is suddenly put under too much strain, warming up and increasing the level of activity gradually gives your muscles time to loosen up and puts less pressure on the tendon.
