Typically an overuse
injury, Achilles tendinitis affects the connective tissue between the calf and the heel. When you walk, run or otherwise use your leg to push your body upward, the Achilles tendon is engaged. Using
the tendon frequently and with high intensity often results in tendinitis -- a swollen Achilles tendon that makes it difficult and sometimes painful to continue high-impact activities.
In some cases, Achilles Tendinitis can be caused by physical activity without a proper warm up or trauma, such as falling, to cause an overstressing of the muscle and tendon. Other causes include
repetitive overuse syndrome, such as a job that required frequent heel lifting. Biomechanical causes such as pronation (or fallen arches) will cause the heel (calcaneus) to lean slightly, putting the
undue stress on the Achilles tendon and the calf muscles. Most pain can be felt at the back of the heel or the point at which the calf muscle becomes a tendon three quarters of the distance down from
the knee. Discomfort can be felt especially when jumping or when lifting the heel off the ground. Swelling and redness can often be seen at the back of the heel and touching the area would cause a
tender sensation. In extreme cases, the tendon can become torn or rupture entirely which would cause bruising or an inability to put pressure on the foot.
Gradual onset of pain and stiffness over the tendon, which may improve with heat or walking and worsen with strenuous activity. Tenderness of the tendon on palpation. There may also be crepitus and
swelling. Pain on active movement of the ankle joint. Ultrasound or MRI may be necessary to differentiate tendonitis from a partial tendon rupture.
Studies such as x-rays and MRIs are not usually needed to make the diagnosis of tendonitis. While they are not needed for diagnosis of tendonitis, x-rays may be performed to ensure there is no other
problem, such as a fracture, that could be causing the symptoms of pain and swelling. X-rays may show evidence of swelling around the tendon. MRIs are also good tests identify swelling, and will show
evidence of tendonitis. However, these tests are not usually needed to confirm the diagnosis; MRIs are usually only performed if there is a suspicion of another problem that could be causing the
symptoms. Once the diagnosis of tendonitis is confirmed, the next step is to proceed with appropriate treatment. Treatment depends on the specific type of tendonitis. Once the specific diagnosis is
confirmed, the appropriate treatment of tendonitis can be initiated.
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.
If non-surgical approaches fail to restore the tendon to its normal condition, surgery may be necessary. The foot and ankle surgeon will select the best procedure to repair the tendon, based upon the
extent of the injury, the patient?s age and activity level, and other factors.
A 2014 study looked at the effect of using foot orthotics on the Achilles tendon. The researchers found that running with foot orthotics resulted in a significant decrease in Achilles tendon load
compared to running without orthotics. This study indicates that foot orthoses may act to reduce the incidence of chronic Achilles tendon pathologies in runners by reducing stress on the Achilles
tendon1. Orthotics seem to reduce load on the Achilles tendon by reducing excessive pronation,
