What Leads To Achilles Tendon Pain
Overview
Inflammation of the Achilles tendon.The Achilles is the large tendon connecting the two major calf muscles, gastrocnemius and soleus, to the back of the heel bone. Under too much stress, the tendon tightens and is forced to work too hard. This causes it to become inflamed (that is tendinitis), and, over time, can produce a covering of scar tissue, which is less flexible than the tendon. If the inflamed Achilles continues to be stressed, it can tear or rupture.
Causes
The calf is under a lot of strain when running: it is not only put on stretch during landing of the foot, but it also has to produce the tension needed to support body weight and absorb the shock of landing. This is what is called an ?eccentric load?. Excessive eccentric loading - either by way of a dramatic increase in mileage, or excessive hill running, or faulty running posture - could very well be the cause of a runner?s achilles tendinitis. The calf strain translates downward into the achilles tendon where it attaches to the heel, and inflammation ensues. Inflammation then causes scarring and fibrosis of tissues, which in turn inflicts pain upon stretching or use. Risk factors for Achilles tendinitis also include spending prolonged amounts of time standing or walking.
Symptoms
Most cases of Achilles tendonitis start out slowly, with very little pain, and then grow worse over time. Some of the more common symptoms include mild pain or an ache above the heel and in the lower leg, especially after running or doing other physical activities, pain that gets worse when walking uphill, climbing stairs, or taking part in intense or prolonged exercise, stiffness and tenderness in the heel, especially in the morning, that gradually goes away, swelling or hard knots of tissue in the Achilles tendon, a creaking or crackling sound when moving the ankle or pressing on the Achilles tendon, weakness in the affected leg.
Diagnosis
A podiatrist can usually make the diagnosis by clinical history and physical examination alone. Pain with touching or stretching the tendon is typical. There may also be a visible swelling to the tendon. The patient frequently has difficulty plantarflexing (pushing down the ball of the foot and toes, like one would press on a gas pedal), particularly against resistance. In most cases X-rays don't show much, as they tend to show bone more than soft tissues. But X-rays may show associated degeneration of the heel bone that is common with Achilles Tendon problems. For example, heel spurs, calcification within the tendon, avulsion fractures, periostitis (a bruising of the outer covering of the bone) may all be seen on X-ray. In cases where we are uncertain as to the extent of the damage to the tendon, though, an MRI scan may be necessary, which images the soft tissues better than X-rays. When the tendon is simply inflamed and not severely damaged, the problem may or may not be visible on MRI. It depends upon the severity of the condition.
Nonsurgical Treatment
Physical therapy is the first and most useful defense for achilles tendonitis because of the two presentations outlined above. Treatments for the two types are quite different in approach. Midsubstance tendinitis responds well to stretching, whereas insertional tendnitis tends to be aggravated more by it. Depend on your trusted physical therapist to differentiate between the two and follow their guidelines on exercises and running modifications. Running gait patterns that show excessive ?sinking postures? tend to point to the source of achilles tendon problems. Altering your gait in the midstance phase of the cycle can reduce the load on the tendon dramatically and thereby reduce pain. Rely on your running physical therapist for proper guidance on altering your gait the right way. Stride Strong?s Portland Running Clinic gait analysis can identify and fix potential issues before pain sets in. Icing at the onset of acute achilles pain (i.e. when the injury is fresh and new) would help control the inflammation. Your next step should be to call our number for an appointment.
Surgical Treatment
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.
Prevention
To prevent Achilles tendonitis or tendonosis from recurring after surgical or non-surgical treatment, the foot and ankle surgeon may recommend strengthening and stretching of the calf muscles through daily exercises. Wearing proper shoes for the foot type and activity is also important in preventing recurrence of the condition.
