Achilles tendinitis. Achilles tendonitis is inflammation of the Achilles tendon, the largest tendon in the body, which runs from the calf to the heel bone. Noninsertional Achilles tendonitis affects fibers in the middle of the tendon. Insertional Achilles tendonitis affects the lower portion of the tendon where it attaches to the heel bone. Both types can result from repetitive stress to the tendon or from overstressing the tendon during exercise. Damaged tendon fibers can calcify and bone spurs can form where the tendon attaches to the bone. Symptoms may include pain and stiffness of the tendon – which may occur from either inactivity (such as first thing in the morning) or after activity – thickening or swelling of the tendon or bone spurs.
Achilles tendonitis is an overuse injury that is common especially to joggers and jumpers, due to the repetitive action and so may occur in other activities that requires the same repetitive action. Most tendon injuries are the result of gradual wear and tear to the tendon from overuse or ageing. Anyone can have a tendon injury, but people who make the same motions over and over in their jobs, sports, or daily activities are more likely to damage a tendon. A tendon injury can happen suddenly or little by little. You are more likely to have a sudden injury if the tendon has been weakened over time. Common causes of Achilles tendonitis include, over-training or unaccustomed use,?too much too soon?. Sudden change in training surface e.g. grass to bitumen. Flat (over-pronated) feet, High foot arch with tight Achilles tendon. tight hamstring (back of thigh) and calf muscles, toe walking (or constantly wearing high heels). Poorly supportive footwear, hill running. Poor eccentric strength.
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.
Your physiotherapist or sports doctor can usually confirm the diagnosis of Achilles tendonitis in the clinic. They will base their diagnosis on your history, symptom behaviour and clinical tests. Achilles tendons will often have a painful and prominent lump within the tendon. Further investigations include US scan or MRI. X-rays are of little use in the diagnosis.
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.
Surgery can be done to remove hardened fibrous tissue and repair any small tendon tears as a result of repetitive use injuries. This approach can also be used to help prevent an Achilles tendon rupture. If your Achilles tendon has already ruptured or torn, Achilles tendon surgery can be used to reattach the ends of the torn tendon. This approach is more thorough and definitive compared to non surgical treatment options discussed above. Surgical reattachment of the tendon also minimizes the change of re-rupturing the Achilles tendon.
Warm up slowly by running at least one minute per mile slower than your usual pace for the first mile. Running backwards during your first mile is also a very effective way to warm up the Achilles, because doing so produces a gentle eccentric load that acts to strengthen the tendon. Runners should also avoid making sudden changes in mileage, and they should be particularly careful when wearing racing flats, as these shoes produce very rapid rates of pronation that increase the risk of Achilles tendon injury. If you have a tendency to be stiff, spend extra time stretching. If you?re overly flexible, perform eccentric load exercises preventively. Lastly, it is always important to control biomechanical alignment issues, either with proper running shoes and if necessary, stock or custom orthotics.
