Overview
The Achilles is a large tendon that connects two major calf muscles to the back of the heel bone. If this tendon is overworked and tightens, the collagen fibres of the tendon may break, causing inflammation and pain. This can result in scar tissue formation, a type of tissue that does not have the flexibility of tendon tissue. Four types of Achilles injuries exist, 1) Paratendonitis – involves a crackly or crepitus feeling in the tissues surrounding the Achilles tendon. 2) Proliferative Tendinitis – the Achilles tendon thickens as a result of high tension placed on it. 3) Degenerative Tendinitis – a chronic condition where the Achilles tendon is permanently damaged and does not regain its structure. 4) Enthesis – an inflammation at the point where the Achilles tendon inserts into the heel bone.
Causes
Tendinitis can result from an injury or over-use. Improper stretching prior to exertion or incorrect form during physical activity can also contribute to the development of tendinitis. Some people, including those with ?flat feet,? tight tendons or arthritis, are particularly prone to tendinitis.
Symptoms
Symptoms include pain in the heel and along the tendon when walking or running. The area may feel painful and stiff in the morning. The tendon may be painful to touch or move. The area may be swollen and warm. You may have trouble standing up on one toe.
Diagnosis
Examination of the achilles tendon is inspection for muscle atrophy, swelling, asymmetry, joint effusions and erythema. Atrophy is an important clue to the duration of the tendinopathy and it is often present with chronic conditions. Swelling, asymmetry and erythema in pathologic tendons are often observed in the examination. Joint effusions are uncommon with tendinopathy and suggest the possibility of intra-articular pathology. Range of motion testing, strength and flexibility are often limited on the side of the tendinopathy. Palpation tends to elicit well-localized tenderness that is similar in quality and location to the pain experienced during activity. Physical examinations of the Achilles tendon often reveals palpable nodules and thickening. Anatomic deformities, such as forefoot and heel varus and excessive pes planus or foot pronation, should receive special attention. These anatomic deformities are often associated with this problem. In case extra research is wanted, an echography is the first choice of examination when there is a suspicion of tendinosis. Imaging studies are not necessary to diagnose achilles tendonitis, but may be useful with differential diagnosis. Ultrasound is the imaging modality of first choice as it provides a clear indication of tendon width, changes of water content within the tendon and collagen integrity, as well as bursal swelling. MRI may be indicated if diagnosis is unclear or symptoms are atypical. MRI may show increased signal within the Achilles.
Nonsurgical Treatment
The latest studies on Achilles tendonitis recommend a treatment plan that incorporates the following three components. Treatment of the inflammation. Strengthening of the muscles that make up the Achilles tendon using eccentric exercise. These are a very specific type of exercise that has been shown in multiple studies to be a critical component of recovering from Achilles tendonitis. Biomechanical control (the use of orthotics and proper shoes). Shockwave therapy.
Surgical Treatment
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.
Prevention
Stretching of the gastrocnemius (keep knee straight) and soleus (keep knee bent) muscles. Hold each stretch for 30 seconds, relax slowly. Repeat stretches 2 – 3 times per day. Remember to stretch well before running strengthening of foot and calf muscles (eg, heel raises) correct shoes, specifically motion-control shoes and orthotics to correct overpronation. Gradual progression of training programme. Avoid excessive hill training. Incorporate rest into training programme.
Achilles tendonitis, also sometimes called Achilles tendinitis, is a painful and often debilitating inflammation of the Achilles tendon (heel cord). 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 leg muscles to the foot. The Achilles tendon gives us the ability to rise up on our toes, facilitating the act of walking, and Achilles tendonitis can make walking almost impossible. There are three stages of tendon inflammation, Peritenonitis, Tendinosis, Peritenonitis with tendinosis. Peritenonitis is characterized by localized pain during or following activity. As this condition progresses, pain often develops earlier on during activity, with decreased activity, or while at rest. Tendinosis is a degenerative condition that usually does not produce symptoms (i.e., is asymptomatic). It may cause swelling or a hard knot of tissue (nodule) on the back of the leg. Peritenonitis with tendinosis results in pain and swelling with activity. As this condition progresses, partial or complete tendon rupture may occur. The overall incidence of Achilles tendonitis is unknown. The condition occurs in approximately 6-18% of runners, and also is more common in athletes, especially in sports that involve jumping (e.g., basketball), and in people who do a lot of walking. Achilles tendonitis that occurs as a result of arthritis in the heel is more common in people who are middle aged and older.
The Achilles tendon is the largest tendon in the body. It connects the calf muscles to the heel and is active during almost all activities including walking, jumping, and swimming. This dense tendon can withstand large forces, but can become inflamed and painful during periods of overuse. Pain results from inflammation (tendonitis) or a degenerating tendon (tendinosis). Achilles tendon pathologies include rupture and tendonitis. Many experts now believe, however, that tendonitis is a misleading term that should no longer be used, because signs of true inflammation are almost never present on histologic examination. Instead, the following histopathologically determined nomenclature has evolved. Paratenonitis: Characterized by paratenon inflammation and thickening, as well as fibrin adhesions. Tendinosis: Characterized by intrasubstance disarray and degeneration of the tendon.
