Inflammation of the Achilles tendon.The Achilles is the large tendon connecting the two major calf muscles, gastrocnemius and soleus, to the back of the heel bone. Under too much stress, the tendon tightens and is forced to work too hard. This causes it to become inflamed (that is tendinitis), and, over time, can produce a covering of scar tissue, which is less flexible than the tendon. If the inflamed Achilles continues to be stressed, it can tear or rupture.
Possible factors leading to the development of Achilles tendonitis include the following. Implementing a new exercise regiment such as running uphill or climbing stairs. Change in exercise routine, boosting intensity or increasing duration. Shoes worn during exercise lack support, either because the soles are worn out or poor shoe design. Omitting proper warm-up prior to strenuous exercise. Running on a hard or uneven surface. Deformation in foot such as a flat arch, or any anatomic variation that puts unnecessary strain on the Achilles tendon.
The pain associated with Achilles tendinitis typically begins as a mild ache in the back of the leg or above the heel after running or other sports activity. Episodes of more severe pain may occur after prolonged running, stair climbing or sprinting. You might also experience tenderness or stiffness, especially in the morning, which usually improves with mild activity. If you experience persistent pain around the Achilles tendon, call your doctor. Seek immediate medical attention if the pain or disability is severe. You may have a torn (ruptured) Achilles tendon.
A thorough subjective and objective examination from a physiotherapist is usually sufficient to diagnose an Achilles injury such as Achilles tendonitis. Occasionally, further investigations such as an Ultrasound, X-ray or MRI scan may be required to assist with diagnosis and assess the severity of the condition.
Conservative management of Achilles tendinosis and paratenonitis includes the following. Physical therapy. Eccentric exercises are the cornerstone of strengthening treatment, with most patients achieving 60-90% pain relief. Orthotic therapy in Achilles tendinosis consists of the use of heel lifts. Nonsteroidal anti-inflammatory drugs (NSAIDs): Tendinosis tends to be less responsive than paratenonitis to NSAIDs. Steroid injections. Although these provide short-term relief of painful symptoms, there is concern that they can weaken the tendon, leading to rupture. Vessel sclerosis. Platelet-rich plasma injections. Nitric oxide. Shock-wave therapy. Surgery may also be used in the treatment of Achilles tendinosis and paratenonitis. In paratenonitis, fibrotic adhesions and nodules are excised, freeing up the tendon. Longitudinal tenotomies may be performed to decompress the tendon. Satisfactory results have been obtained in 75-100% of cases. In tendinosis, in addition to the above procedures, the degenerated portions of the tendon and any osteophytes are excised. Haglund?s deformity, if present, is removed. If the remaining tendon is too thin and weak, the plantaris or flexor hallucis longus tendon can be weaved through the Achilles tendon to provide more strength. The outcome is generally less favorable than it is in paratenonitis surgery.
In cases of severe, long-term Achilles tendonitis the sheath may become thick and fibrous. In these cases surgery may be recommended. Surgery aims to remove the fibrous tissue and repair any tears in the tendon. A cast or splint will be required after the operation and a recovery program including physiotherapy, specific exercises and a gradual return to activity will be planned.
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.
