Achilles tendinitis is
inflammation of the Achilles tendon, the fibrous tissue that connects the heel to the calf muscles. This condition is often caused by irritation of the tendon and typically affects those who play
sports. However, older individuals who suffer from arthritis may also be affected. Achilles tendinitis is typically the first stage of an Achilles tendon injury and should be treated right away.
Without treatment, the tendon can tear or rupture, which may require surgery.
Achilles tendonitis is an overuse injury. Too much too soon is the common cause of overuse injuries, however other factors can contribute to developing the condition. An increase in activity, either
distance, speed or a sudden change to running up hills. As a rule of thumb distance runners should increase their mileage by no more than 10% per week. A change of footwear or training surface for
example suddenly running on soft sand can cause the heel to drop lower than normal making the tendon stretch further than it is used to. Weak calf muscles can tighten or go into partial spasm which
again increases the strain on the achilles tendon by shortening the muscle. Running up hills - the achilles tendon has to stretch more than normal on every stride. This is fine for a while but will
mean the tendon will fatigue sooner than normal. Overpronation or feet which roll in when running can place an increased strain on the achilles tendon. As the foot rolls in (flattens) the lower leg
also rotates inwards which places twisting stresses on the tendon. Wearing high heels constantly shortens the tendon and calf muscles. When exercising in flat running shoes, the tendon is stretched
beyond its normal range which places an abnormal strain on the tendon.
Patients with an Achilles tendon rupture frequently present with complaints of a sudden snap in the lower calf associated with acute, severe pain. The patient reports feeling like he or she has been
shot, kicked, or cut in the back of the leg, which may result in an inability to ambulate further. A patient with Achilles tendon rupture will be unable to stand on his or her toes on the affected
side. Tendinosis is often pain free. Typically, the only sign of the condition may be a palpable intratendinous nodule that accompanies the tendon as the ankle is placed through its range of motion
(ROM). Patients with paratenonitis typically present with warmth, swelling, and diffuse tenderness localized 2-6 cm proximal to the tendon's insertion. Paratenonitis with tendinosis. This is
diagnosed in patients with activity-related pain, as well as swelling of the tendon sheath and tendon nodularity.
To confirm the diagnosis and consider what might be causing the problem, it?s important to see your doctor or a physiotherapist. Methods used to make a diagnosis may include, medical history,
including your exercise habits and footwear, physical examination, especially examining for thickness and tenderness of the Achilles tendon, tests that may include an x-ray of the foot, ultrasound
and occasionally blood tests (to test for an inflammatory condition), and an MRI scan of the tendon.
As with most soft tissue injuries the initial treatment is RICE - Rest, Ice, Compression and Elevation. In the early phase you?ll be unable to walk without a limp, so your Achilles tendon needs some
active rest from weight-bearing loads. You may need to be non or partial-weight-bearing, utilise crutches, a wedged achilles walking boot or heel wedges to temporarily relieve some of the pressure on
the Achilles tendon. Your physiotherapist will advise you on what they feel is best for you. Ice is a simple and effective modality to reduce your pain and swelling. Please apply for 20-30 minutes
each 2 to 4 hours during the initial phase or when you notice that your injury is warm or hot. Anti-inflammatory medication (if tolerated) and natural substances eg arnica may help reduce your pain
and swelling. However, it is best to avoid anti-inflammatory drugs during the initial 48 to 72 hours when they may encourage additional bleeding. Most people can tolerate paracetamol as a pain
reducing medication. As you improve a kinesio style supportive taping will help to both support the injured soft tissue.
If non-surgical treatment fails to cure the condition then surgery can be considered. This is more likely to be the case if the pain has been present for six months or more. The nature of the surgery
depends if you have insertional, or non-insertional disease. In non-insertional tendonosis the damaged tendon is thinned and cleaned. The damage is then repaired. If there is extensive damage one of
the tendons which moves your big toe (the flexor hallucis longus) may be used to reinforce the damaged Achilles tendon. In insertional tendonosis there is often rubbing of the tendon by a prominent
part of the heel bone. This bone is removed. In removing the bone the attachment of the tendon to the bone may be weakened. In these cases the attachment of the tendon to the bone may need to be
reinforced with sutures and bone anchors.
Achilles tendinitis cannot always be prevented but the following tips will help you reduce your risk. If you are new to a sport, gradually ramp up your activity level to your desired intensity and
duration. If you experience pain while exercising, stop. Avoid strenuous activity that puts excessive stress on your Achilles tendon. If you have a demanding workout planned, warm up slowly and
thoroughly. Always exercise in shoes that are in good condition and appropriate for your activity or sport. Be sure to stretch your calf muscles and Achilles tendon before and after working out. If
you suffer from Achilles tendinitis make sure you treat it properly and promptly. If self-care techniques don?t work, don?t delay. Book a consultation with a foot care expert or you may find yourself
sidelined from your favourite sports and activities.
