Which are the Primary Treatments And Causes Of Achilles Tendinitis
Overview
Achilles tendinitis is an overuse injury of the Achilles (uh-KIL-eez) tendon, the band of tissue that connects calf muscles at the back of the lower leg to your heel bone. Under too much stress, the tendon tightens and is forced to work too hard. This causes it to become inflamed (that?s Achilles 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. Achilles tendinitis most commonly occurs in runners who have suddenly increased the intensity or duration of their runs. It?s also common in middle-aged people who play sports, such as tennis or basketball, only on the weekends. Most cases of Achilles tendinitis can be treated with relatively simple, at-home care under your doctor?s supervision. Self-care strategies are usually necessary to prevent recurring episodes. More-serious cases of Achilles tendinitis can lead to tendon tears (ruptures) that may require surgical repair.
Causes
There are hundreds of tendons scattered throughout our body, but it tends to be a small handful of specific tendons that cause problems. These tendons usually have an area of poor blood supply that leads to tissue damage and poor healing response. This area of a tendon that is prone to injury is called a "watershed zone," an area when the blood supply to the tendon is weakest. In these watershed zones, they body has a hard time delivering oxygen and nutrients necessary for tendon healing, that's why we see common tendon problems in the same parts of the body. Tendonitis is most often an overuse injury. Often people begin a new activity or exercise that causes the tendon to become irritated. Tendon problems are most common in the 40-60 year old age range. Tendons are not as elastic and forgiving as in younger individuals, yet bodies are still exerting with the same force. Occasionally, there is an anatomical cause for tendonitis. If the tendon does not have a smooth path to glide along, it will be more likely to become irritated and inflamed. In these unusual situations, surgical treatment may be necessary to realign the tendon.
Symptoms
Symptoms of Achilles tendinitis and tendinosis include recurring localized heel pain, sometimes severe, along the achilles tendon during or after exercise. Pain often begins after exercise and gradually worsens. Morning tenderness or stiffness about an inch and a half above the point where the Achilles tendon is attached to the heel bone. Sluggishness in your leg. Mild to severe swelling. Stiffness that generally diminishes as the tendon warms up with use.
Diagnosis
A podiatrist can usually make the diagnosis by clinical history and physical examination alone. Pain with touching or stretching the tendon is typical. There may also be a visible swelling to the tendon. The patient frequently has difficulty plantarflexing (pushing down the ball of the foot and toes, like one would press on a gas pedal), particularly against resistance. In most cases X-rays don't show much, as they tend to show bone more than soft tissues. But X-rays may show associated degeneration of the heel bone that is common with Achilles Tendon problems. For example, heel spurs, calcification within the tendon, avulsion fractures, periostitis (a bruising of the outer covering of the bone) may all be seen on X-ray. In cases where we are uncertain as to the extent of the damage to the tendon, though, an MRI scan may be necessary, which images the soft tissues better than X-rays. When the tendon is simply inflamed and not severely damaged, the problem may or may not be visible on MRI. It depends upon the severity of the condition.
Nonsurgical Treatment
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.
Surgical Treatment
Chronic Achilles tendon tears can be more complicated to repair. A tendon that has torn and retracted (pulled back) into the leg will scar in the shortened position over time. Restoring normal tendon length is usually not an issue when surgery is performed within a few weeks of the injury. However, when there has been a delay of months or longer, the treatment can be more complicated. Several procedures can be used to add length to a chronic Achilles tear. A turndown procedure uses tissue folded down from the top of the calf to add length to the Achilles tendon. Tendon transfers from other tendons of the ankle can also be performed to help restore function of the Achilles. The results of surgery in a chronic situation are seldom as good as an acute repair. However, in some patients, these procedures can help restore function of a chronically damaged Achilles.
Prevention
Stay in good shape year-round and try to keep your muscles as strong as they can be. Strong, flexible muscles work more efficiently and put less stress on your tendon. Increase the intensity and length of your exercise sessions gradually. This is especially important if you've been inactive for a while or you're new to a sport. Always warm up before you go for a run or play a sport. If your muscles are tight, your Achilles tendons have to work harder to compensate. Stretch it out. Stretch your legs, especially your calves, hamstrings, quadriceps, and thigh muscles - these muscles help stabilize your knee while running. Get shoes that fit properly and are designed for your sport. If you're a jogger, go to a running specialty store and have a trained professional help you select shoes that match your foot type and offer plenty of support. Replace your shoes before they become worn out. Try to run on softer surfaces like grass, dirt trails, or synthetic tracks. Hard surfaces like concrete or asphalt can put extra pressure on the joints. Also avoid running up or down hills as much as possible. Vary your exercise routine. Work different muscle groups to keep yourself in good overall shape and keep individual muscles from getting overused. If you notice any symptoms of Achilles tendonitis, stop running or doing activities that put stress on your feet. Wait until all the pain is gone or you have been cleared to start participating again by a doctor.
