Achilles tendinitis describes an inflammatory change of the Achilles tendon without a tear of the tendon. Achilles tendinitis may be acute or chronic. The onset of pain is usually unilateral but may be found bilaterally. Achilles tendinitis is common in the third or fourth decade of life in patients who are active with sports or in jobs that require physical labor. Pain is described at the insertion of the tendon in the heel bone or in the body of the tendon.
Unusual use or overuse of the lower leg muscles and Achilles tendon is usually the cause of Achilles tendinitis. Repetitive jumping, kicking, and sprinting can lead to Achilles tendinitis in both recreational and competitive athletes. Runners, dancers, and athletes over age 65 are especially at risk. Sudden increases in training or competition can also inflame your Achilles tendon. For example, adding hills, stair-climbing, or sprinting to your running workout puts extra stress on your Achilles tendon. Improper technique during training can also strain the tendon. Intense running or jumping without stretching and strengthening your lower leg muscles can put you at risk regardless of your age or fitness level. Running on tight, exhausted, or fatigued calf muscles can put added stress on your Achilles tendon, as your tendon may not be ready to quickly start a workout after a period of inactivity. Direct blows or other injuries to the ankle, foot, or lower leg may pull your Achilles tendon too far and stretch the tissue. A hard contraction of the calf muscles, such as can happen when you push for the final sprint in a race, can strain the tendon. People whose feet roll inward, a condition called overpronation, are particularly at risk. Sometimes, shoes with too much heel cushioning put extra strain on the Achilles tendon.
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.
Laboratory studies usually are not necessary in evaluating and diagnosing an Achilles tendon rupture or injury, although evaluation may help to rule out some of the other possibilities in the differential diagnosis. Imaging studies. Plain radiography: Radiographs are more useful for ruling out other injuries than for ruling in Achilles tendon ruptures. Ultrasonography: Ultrasonography of the leg and thigh can help to evaluate the possibility of deep venous thrombosis and also can be used to rule out a Baker cyst; in experienced hands, ultrasonography can identify a ruptured Achilles tendon or the signs of tendinosis. Magnetic resonance imaging (MRI): MRI can facilitate definitive diagnosis of a disrupted tendon and can be used to distinguish between paratenonitis, tendinosis, and bursitis.
See your doctor or sports physiotherapist for further advice. You may be prescribed anti-inflammatory medicine and a rehabilitation programme. Sometimes, the ankle may be put into a walking boot or cast to immobilise the ankle in the short term. Gentle calf stretching is the first stage of rehabilitation. Don?t stretch to the point of pain. Strengthening the Achilles tendon is the second stage. Your doctor or sports physiotherapist will be able to advise you on exercises for this. Special exercises called eccentric calf raises, that contract the calf muscle as it is lengthening (during the lowering part of the movement), are the standard exercise used in the rehabilitation of Achilles tendon injuries. Sometimes a heel raise or orthotics may be useful. As symptoms resolve, resume normal weight-bearing activities gradually. Avoid running until all tenderness has gone. Swimming or cycling in low gear are good replacement activities.
Most people will improve with simple measures or physiotherapy. A small number continue to have major problems which interfere with their lifestyle. In this situation an operation may be considered. If an operation is being considered, the surgeon will interview you and examine you again and may want you to have further treatment before making a decision about an operation. Before undergoing Achilles tendonitis surgery, London based patients, and those who can travel, will be advised to undergo a scan, which will reveal whether there is a problem in the tendon which can be corrected by surgery. Patients will also have the opportunity to ask any questions and raise any concerns that they may have, so that they can proceed with the treatment with peace of mind.
Suggestions to reduce your risk of Achilles tendonitis include, incorporate stretching into your warm-up and cool-down routines, maintain an adequate level of fitness for your sport, avoid dramatic increases in sports training, if you experience pain in your Achilles tendon, rest the area. Trying to ?work through? the pain will only make your injury worse, wear good quality supportive shoes appropriate to your sport. If there is foot deformity or flattening, obtain orthoses, avoid wearing high heels on a regular basis. Maintaining your foot in a ?tiptoe? position shortens your calf muscles and reduces the flexibility of your Achilles tendon. An inflexible Achilles tendon is more susceptible to injury, maintain a normal healthy weight.
