Achilles tendinosis (also known as Achilles tendinopathy) is a soreness and stiffness that comes on gradually and continues to worsen until treated. It is a common injury among middle and long distance runners. The severity of Achilles tendinosis can be broken down into four stages, each of which can be measured in terms of how the Achilles tendon feels during exercise, the amount of stiffness and creaking, and Achilles tendon?s soreness to the touch (the Achilles tendon pinch test). The four stages, or grades, are, No pain during exercise, but there is some discomfort in the morning when first getting out of bed. The stiffness and creaking go away after a few minutes and are fine the rest of the day. Lightly pinching the Achilles tendon with the forefinger and thumb in the morning or after exercise will probably indicate soreness. Pain during exercise or running, but performance is not affected. The stiffness and creaking continue to appear when first getting out of bed and continue to disappear shortly afterward. Lightly pinching the Achilles tendon with the forefinger and thumb in the morning or after exercise will indicate soreness. Pain during exercise or running that is detrimental to performance. The stiffness and creaking continue to appear when first getting out of bed, but may continue for some time and reappear at other points during the day. Lightly pinching the Achilles tendon with the forefinger and thumb in the morning or after exercise will indicate soreness. Hurts too much to exercise or run. The stiffness and creaking continue to appear when first getting out of bed, but may continue for most of the day. Lightly pinching the Achilles tendon with the forefinger and thumb at almost any time of day will indicate soreness.
Achilles tendonitis is an overuse injury. Too much too soon is the common cause of overuse injuries, however other factors can contribute to developing the condition. An increase in activity, either distance, speed or a sudden change to running up hills. As a rule of thumb distance runners should increase their mileage by no more than 10% per week. A change of footwear or training surface for example suddenly running on soft sand can cause the heel to drop lower than normal making the tendon stretch further than it is used to. Weak calf muscles can tighten or go into partial spasm which again increases the strain on the achilles tendon by shortening the muscle. Running up hills – the achilles tendon has to stretch more than normal on every stride. This is fine for a while but will mean the tendon will fatigue sooner than normal. Overpronation or feet which roll in when running can place an increased strain on the achilles tendon. As the foot rolls in (flattens) the lower leg also rotates inwards which places twisting stresses on the tendon. Wearing high heels constantly shortens the tendon and calf muscles. When exercising in flat running shoes, the tendon is stretched beyond its normal range which places an abnormal strain on the tendon.
Paratenonitis presents in younger people. Symptoms start gradually and spontaneously. Aching and burning pain is noted especially with morning activity. It may improve slightly with initial activity, but becomes worse with further activity. It is aggravated by exercise. Over time less exercise is required to cause the pain. The Achilles tendon is often enlarged, warm and tender approximately 1 to 4 inches above its heel insertion. Sometimes friction is noted with gentle palpation of the tendon during ankle motion. Tendinosis presents similarly but typically in middle-aged people. If severe pain and limited walking ability are present, it may indicate a partial tear of the tendon.
Confirming Achilles tendonitis may involve imaging tests. X-rays provide images of the bones of the foot and leg. Magnetic resonance imaging (MRI) is useful for detecting ruptures and degeneration of tissue. Ultrasound shows tendon movement, related damage, and inflammation.
In order to treat the symptoms, antiflogistics or other anti-inflammatory therapy are often used. However these forms of therapy usually cannot prevent the injury to live on. Nevertheless patients will always have to be encouraged to execute less burdening activities, so that the burden on the tendon decreases as well. Complete immobilisation should however be avoided, since it can cause atrophy. Passive rehabilitation, Mobilisations can be used for dorsiflexion limitation of the talocrural joint and varus- or valgus limitation of the subtalar joint. Deep cross frictions (15 min). It?s effectiveness is not scientifically proven and gives limited results. Recently, the use of Extracorporal Shock Wave Therapy was proven. Besides that, the application of ice can cause a short decrease in pain and in swelling. Even though cryotherapy 2, 5 was not studied very thoroughly, recent research has shown that for injuries of soft tissue, applications of ice through a wet towel for ten minutes are the most effective measures. Active rehabilitation, An active exercise program mostly includes eccentric exercises. This can be explained by the fact that eccentric muscle training will lengthen the muscle fibres, which stimulates the collagen production. This form of therapy appears successful for mid-portion tendinosis, but has less effect with insertion tendinopathy. The sensation of pain sets the beginning burdening of the patient and the progression of the exercises.
For paratenonitis, a technique called brisement is an option. Local anesthetic is injected into the space between the tendon and its surrounding sheath to break up scar tissue. This can be beneficial in earlier stages of the problem 30 to 50 percent of the time, but may need to be repeated two to three times. Surgery consists of cutting out the surrounding thickened and scarred sheath. The tendon itself is also explored and any split tears within the tendon are repaired. Motion is started almost immediately to prevent repeat scarring of the tendon to the sheath and overlying soft tissue, and weight-bearing should follow as soon as pain and swelling permit, usually less than one to two weeks. Return to competitive activity takes three to six months. Since tendinosis involves changes in the substance of the tendon, brisement is of no benefit. Surgery consists of cutting out scar tissue and calcification deposits within the tendon. Abnormal tissue is excised until tissue with normal appearance appears. The tendon is then repaired with suture. In older patients or when more than 50 percent of the tendon is removed, one of the other tendons at the back of the ankle is transferred to the heel bone to assist the Achilles tendon with strength as well as provide better blood supply to this area.
As with all injuries, prevention is your best defense especially with injuries that are as painful and inconvenient as Achilles tendonitis. Options for how to prevent Achilles tendonitis include, stretching- Stretching properly, starting slowly, and increasing gradually will be critical if you want to avoid Achilles tendonitis. To help maintain flexibility in the ankle joint, begin each day with a series of stretches and be certain to stretch prior to, and after, any exercise or excessive physical activity. Orthotics and Heel Support- Bio-mechanically engineered inserts and heel cups can be placed in your shoes to correct misalignments or bolster the support of your foot and are available without a prescription. The temporary heel padding that these provide reduces the length that the Achilles tendon stretches each time you step, making it more comfortable to go about your daily routine. Proper Footwear- Low-heeled shoes with good arch support and shock absorption are best for the health of your foot. Look into heel wedges and other shoe inserts to make sure that your everyday foot mechanics are operating under ideal conditions.
