tendon is the thickest and strongest tendon in your body, connecting your calf muscles to the back of your heel. Virtually all of the force generated when you ?toe off? the ground during running is
transmitted by the Achilles, and this force can be as much as three times your body weight. And the faster you run, the more strain you put on the Achilles tendon. As such, it?s prone to injury in
many runners, but particularly those who do a lot of fast training, uphill running, or use a forefoot-striking style. Achilles tendon injuries account for 5-12% of all running injuries, and occur
disproportionately in men. This may be because of the faster absolute speeds men tend to train at, or may be due to other biomechanical factors.
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.
Paratenonitis presents in younger people. Symptoms start gradually and spontaneously. Aching and burning pain is noted especially with morning activity. It may improve slightly with initial activity,
but becomes worse with further activity. It is aggravated by exercise. Over time less exercise is required to cause the pain. The Achilles tendon is often enlarged, warm and tender approximately 1 to
4 inches above its heel insertion. Sometimes friction is noted with gentle palpation of the tendon during ankle motion. Tendinosis presents similarly but typically in middle-aged people. If severe
pain and limited walking ability are present, it may indicate a partial tear of the tendon.
Confirming Achilles tendonitis may involve imaging tests. X-rays provide images of the bones of the foot and leg. Magnetic resonance imaging (MRI) is useful for detecting ruptures and degeneration of
tissue. Ultrasound shows tendon movement, related damage, and inflammation.
In order to treat achilles tendinitis effectively, it is important to complete a thorough examination of the entire lower extremity. Once the true cause is identified, a comprehensive treatment
program can be initiated to reduce inflammation and improve any faulty lower extremity biomechanics. Treatment options may include biomechanical analysis of gait. Splinting/bracing to alleviate the
strain on the tendon. Soft tissue mobilization/manual therapy to decrease inflammation and promote healing of the tendon. Strengthening/flexibility and proprioceptive exercises. Home exercise
program. Modalities for pain and inflammation (i.e. ultrasound, iontophoresis, electrical stimulation, ice). Methods to alter faulty mechanics (i.e taping, orthotics). Education about lifestyle
changes (i.e. proper shoes, activity modification).
In most surgeries, damaged tissue is cleaned out before surgeons make the necessary repairs. However, a new minimally-invasive surgery to repair a torn Achilles tendon actually uses the damaged
tissue to help repair the tear. The percutaneous Achilles repair system, or PARS technique, enables surgeons to better repair a torn Achilles tendon through a smaller incision. This procedure was
recently performed at Houston Methodist Hospital to treat an NFL cornerback, getting him back on field for this season.
Stay in good shape year-round and try to keep your muscles as strong as they can be. Strong, flexible muscles work more efficiently and put less stress on your tendon. Increase the intensity and
length of your exercise sessions gradually. This is especially important if you've been inactive for a while or you're new to a sport. Always warm up before you go for a run or play a sport. If your
muscles are tight, your Achilles tendons have to work harder to compensate. Stretch it out. Stretch your legs, especially your calves, hamstrings, quadriceps, and thigh muscles - these muscles help
stabilize your knee while running. Get shoes that fit properly and are designed for your sport. If you're a jogger, go to a running specialty store and have a trained professional help you select
shoes that match your foot type and offer plenty of support. Replace your shoes before they become worn out. Try to run on softer surfaces like grass, dirt trails, or synthetic tracks. Hard surfaces
like concrete or asphalt can put extra pressure on the joints. Also avoid running up or down hills as much as possible. Vary your exercise routine. Work different muscle groups to keep yourself in
good overall shape and keep individual muscles from getting overused. If you notice any symptoms of Achilles tendonitis, stop running or doing activities that put stress on your feet. Wait until all
the pain is gone or you have been cleared to start participating again by a doctor.
