Achilles tendonitis is commonly seen in athletes who sustain an increase in training load, and is most often due to overuse. Tendons respond poorly to overuse, therefore
healing is slow. This can leave a tendon pathologically defective, which decreases tendon strength and leaves it less able to tolerate load, thus vulnerable to further injury or tendinosis. Extrinsic
factors contributing to this condition include training errors and inappropriate footwear. Intrinsic factors include inflexibility, weakness and malalignment. In other situations, there will be
clinical inflammation, but objective pathologic evidence for cellular inflammation is lacking, and in these conditions the term tendinosis is more appropriate. Tendinosis is a degeneration of the
tendon?s collagen in response to chronic overuse; when overuse is continued without giving the tendon time to heal and rest, such as with repetitive strain injury, tendinosis results. Even tiny
movements, such as clicking a mouse, can cause tendinosis, when done repeatedly.
There are a number of ways a person can develop Achilles tendinitis. Some causes are easier to avoid than others, but being aware of them can aid earlier diagnosis and help prevent serious injury.
Causes of Achilles tendinitis include, using incorrect or worn out shoes when running or exercising. Not warming up properly before exercise. Increasing intensity of exercise too quickly (e.g.
running speed or distance covered). Prematurely introducing hill running or stair climbing to exercise routine. Running on hard or uneven surfaces. Calf muscle is injured or has little flexibility
(this puts a lot of strain on the Achilles tendon). Sudden intense physical activity such as sprinting for the finish line. Achilles tendinitis can also be caused by differences in foot, leg or ankle
anatomy. For example, some people can have flatness in their foot where there would normally be an arch; this puts more strain on the tendon. The FDA has asked that a boxed warning be added to the
prescribing information for fluoroquinolone antibiotics. Patients taking these drugs may experience an increased risk of tendinitis and tendon rupture. Fluoroquinolones include Cipro (ciprofloxacin),
Factive (gemifloxacin), Levaquin (levofloxacin), Avelox (moxifloxacin), Noroxin (norfloxacin), Floxin (ofloxacin) and Proquin (ciprofloxacin hydrochloride). It is important to remember that the risk
for injury is not necessarily gone when the drug is stopped. Cases have been reported in which tendon problems occurred up to several months after the drug was discontinued.
Symptoms can vary from an achy pain and stiffness to the insertion of the Achilles tendon to the heel bone (calcaneus), to a burning that surrounds the whole joint around the inflamed thick tendon.
With this condition, the pain is usually worse during and after activity, and the tendon and joint area can become stiffer the following day. This is especially true if your sheets are pushing down
on your toes and thereby driving your foot into what is termed plantar flexion (downward flexed foot), as this will shorten the tendon all night.
Physicians usually pinch your Achilles tendon with their fingers to test for swelling and pain. If the tendon itself is inflamed, your physician may be able to feel warmth and swelling around the
tissue, or, in chronic cases, lumps of scar tissue. You will probably be asked to walk around the exam room so your physician can examine your stride. To check for complete rupture of the tendon,
your physician may perform the Thompson test. Your physician squeezes your calf; if your Achilles is not torn, the foot will point downward. If your Achilles is torn, the foot will remain in the same
position. Should your physician require a closer look, these imaging tests may be performed. X-rays taken from different angles may be used to rule out other problems, such as ankle fractures. MRI
(magnetic resonance imaging) uses magnetic waves to create pictures of your ankle that let physicians more clearly look at the tendons surrounding your ankle joint.
Treatment options might include anti-inflammatory medication such as ibuprofen which might help with acute achilles inflammation and pain but has not been proven to be beneficial long term and may
even inhibit healing. If the injury is severe then a plaster cast might be applied to immobilize the tendon. Use of electrotherapy such as ultrasound treatment, laser therapy and extracorporeal shock
wave therapy (ESWT) may be beneficial in reducing pain and encouraging healing. Applying sports massage techniques can mobilze the tissues or the tendon itself and help stretch the calf muscles. Some
might give a steroid injection however an injection directly into the tendon is not recommended. Some specialists believe this can increase the risk of a total rupture of the tendon in future. One of
the most effective forms of treatment for achilles tendonitis is a full rehabilitation program consisting of eccentric strengthening exercises. There is now considerable evidence suggesting the
effectiveness of slow eccentric rehabilitation exercises for curing achilles tendon pain.
There are three common procedures that doctor preform in order help heal the tendinitis depending on the location of the tendinitis and amount of damage to the tendon, including: Gastrocnemius
recession - With this surgery doctors lengthen the calf muscles because the tight muscles increases stress on the Achilles tendon. The procedure is typically done on people who have difficulty
flexing their feet even with constant stretching. Debridement and Repair - When there is less than 50% damage in the tendon, it is possible for doctors to remove the injured parts and repair the
healthy portions. This surgery is most done for patients who are suffering from bone spurs or arthritis. To repair the tendon doctors may use metal or plastic anchors to help hold the Achilles tendon
in place. Patients have to wear a boot or cast for 2 weeks or more, depending and the damage done to the tendon. Debridement with Tendon Transfer - When there is more the 50% damage done to the
Achilles tendon, and Achilles tendon transfer is preformed because the remain healthy tissue is not strong enough. The tendon that helps the big toe move is attached to give added strength to the
damaged Achilles. After surgery, most patients don?t notice any difference when they walk or run.
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
