Achilles tendinitis is when the tendon that connects the back of your leg to your heel becomes swollen and painful near the bottom of the foot. This tendon is called the Achilles tendon. It is used for walking, running, and jumping.
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.
There will be a gradual onset of achilles tendon pain over a period of weeks, or even months. The pain will come on during exercise and is constant throughout the training session. Pain will be felt in the achilles tendon when walking especially up hill or up stairs. This is because the achilles is having to stretch further than normal. There is likely to be stiffness in the Achilles tendon especially in the morning or after a long period of rest. This is thought to be due to adhesions between the tendon sheath and the tendon itself. Nodules or lumps may be found in the achilles tendon, particularly 2-4cm above the heel and the skin will appear red. Pain and tenderness will be felt when pressing in on the achilles tendon which is likely to appear thickened or swollen. A creaking sensation may be felt when press the fingers into the sides of the tendon and moving the ankle.This is known as crepitus.
A doctor examines the patient, checking for pain and swelling along the posterior of the leg. The doctor interviews the patient regarding the onset, history, and description of pain and weakness. The muscles, tissues, bones, and blood vessels may be evaluated with imaging studies, such as X-ray, ultrasound, or MRI.
If you have ongoing pain around your Achilles tendon, or the pain is severe, book an appointment with your family physician and ask for a referral to a Canadian Certified Pedorthist. Your Pedorthist will conduct a full assessment of your feet and lower limbs and will evaluate how you run and walk. Based on this assessment, your Pedorthist may recommend a foot orthotic to ease the pressure on your Achilles tendon. As Achilles tendinitis can also be caused by wearing old or inappropriate athletic shoes for your sport, your Pedorthist will also look at your shoes and advise you on whether they have appropriate support and cushioning. New shoes that don?t fit properly or provide adequate support can be as damaging as worn out shoes.
Treating this surgically, there are numerous methods to repair the tendon. Most commonly, Achilles tendon is exposed through an incision at the back of the ankle. After identifying both ends of ruptured tendon, the edges got trimmed and then both ends were sutured together with optimal tension. To get a better outcome with fixation, an anchor may have to be in place in calcaneus, provided the rupture is very low. Care must be taken to avoid injuries to the nerves located adjacent to the tendon.
Maintaining strength and flexibility in the muscles of the calf will help reduce the risk of tendinitis. Overusing a weak or tight Achilles tendon makes you more likely to develop tendinitis.
