Achilles tendonitis (tendinitis), is a painful and often debilitating inflammation of the Achilles tendon than can progress into degeneration which we call Achilles Tendinosis. The Achilles tendon is the largest and strongest tendon in the body. It is located in the back of the lower leg, attaches to the heel bone (calcaneus), and connects the calf muscles to the heel bone. In most cases, Achilles tendonopathy's are overuse injuries are more common among athletes and people who train heavily, however it can also occur in people who are less active. Achilles Tendonitis can vary in severity from a mild pain in the tendon during a particular activity to more severe cases when any form of activity that puts strain on this ligament, even standing or walking, can cause pain.
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.
Patients with this condition typically experience pain in the region of the heel and back of the ankle. In less severe cases, patients may only experience an ache or stiffness in the Achilles region that increases with rest (typically at night or first thing in the morning) following activities which place stress on the Achilles tendon. These activities typically include walking or running excessively (especially uphill or on uneven surfaces), jumping, hopping, performing heel raises or performing calf stretches. The pain associated with this condition may also warm up with activity in the initial stages of injury. As the condition progresses, patients may experience symptoms that increase during sport or activity, affecting performance. Pain may also increase when performing a calf stretch or heel raise (i.e. rising up onto tip toes). In severe cases, patients may walk with a limp or be unable to weight bear on the affected leg. Patients with Achilles tendonitis may also experience swelling, tenderness on firmly touching the Achilles tendon, weakness and sometimes palpable thickening of the affected Achilles tendon when compared with the unaffected side.
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.
In addition to stretching, using a foam roller and getting regular massage to keep the joint mobile can help prevent any problems from starting. If you start to feel inflammation in your tendon or have Achilles tendinitis once, it isn?t necessarily the end of the world. Let it rest and recover, which can sometimes take as long as four to six weeks if you waited until the pain was acute. The real problem is if Achilles tendinitis becomes an ongoing injury. If it keeps recurring, then it?s time for the perpetually injured to examine what they?re doing to cause the problem.
For paratenonitis, a technique called brisement is an option. Local anesthetic is injected into the space between the tendon and its surrounding sheath to break up scar tissue. This can be beneficial in earlier stages of the problem 30 to 50 percent of the time, but may need to be repeated two to three times. Surgery consists of cutting out the surrounding thickened and scarred sheath. The tendon itself is also explored and any split tears within the tendon are repaired. Motion is started almost immediately to prevent repeat scarring of the tendon to the sheath and overlying soft tissue, and weight-bearing should follow as soon as pain and swelling permit, usually less than one to two weeks. Return to competitive activity takes three to six months. Since tendinosis involves changes in the substance of the tendon, brisement is of no benefit. Surgery consists of cutting out scar tissue and calcification deposits within the tendon. Abnormal tissue is excised until tissue with normal appearance appears. The tendon is then repaired with suture. In older patients or when more than 50 percent of the tendon is removed, one of the other tendons at the back of the ankle is transferred to the heel bone to assist the Achilles tendon with strength as well as provide better blood supply to this area.
As with all injuries, prevention is your best defense especially with injuries that are as painful and inconvenient as Achilles tendonitis. Options for how to prevent Achilles tendonitis include, stretching- Stretching properly, starting slowly, and increasing gradually will be critical if you want to avoid Achilles tendonitis. To help maintain flexibility in the ankle joint, begin each day with a series of stretches and be certain to stretch prior to, and after, any exercise or excessive physical activity. Orthotics and Heel Support- Bio-mechanically engineered inserts and heel cups can be placed in your shoes to correct misalignments or bolster the support of your foot and are available without a prescription. The temporary heel padding that these provide reduces the length that the Achilles tendon stretches each time you step, making it more comfortable to go about your daily routine. Proper Footwear- Low-heeled shoes with good arch support and shock absorption are best for the health of your foot. Look into heel wedges and other shoe inserts to make sure that your everyday foot mechanics are operating under ideal conditions.
