Achilles tendonitis is inflammation and tendonosis is degeneration and irregular healing of the achilles tendon. The achilles tendon is the large tendon located in the back of the leg that inserts into the heel. The pain caused by achilles tendonitis/osis can develop gradually without a history of trauma. The pain can be a shooting pain, burning pain, or even an extremely piercing pain. Achilles tendonitis/osis should not be left untreated due to the danger that the tendon can become weak and rupture requiring surgery.
The calf is under a lot of strain when running: it is not only put on stretch during landing of the foot, but it also has to produce the tension needed to support body weight and absorb the shock of landing. This is what is called an ?eccentric load?. Excessive eccentric loading – either by way of a dramatic increase in mileage, or excessive hill running, or faulty running posture – could very well be the cause of a runner?s achilles tendinitis. The calf strain translates downward into the achilles tendon where it attaches to the heel, and inflammation ensues. Inflammation then causes scarring and fibrosis of tissues, which in turn inflicts pain upon stretching or use. Risk factors for Achilles tendinitis also include spending prolonged amounts of time standing or walking.
Gradual onset of pain and stiffness over the tendon, which may improve with heat or walking and worsen with strenuous activity. Tenderness of the tendon on palpation. There may also be crepitus and swelling. Pain on active movement of the ankle joint. Ultrasound or MRI may be necessary to differentiate tendonitis from a partial tendon rupture.
In diagnosing Achilles tendonitis or tendonosis, the surgeon will examine the patient?s foot and ankle and evaluate the range of motion and condition of the tendon. The extent of the condition can be further assessed with x-rays or other imaging modalities.
More often than not, Achilles tendonitis can be treated without surgery. However, recovery may take a few months. The following will can help you recover and get back in the game. Rest is always the most important thing when recovering from an injury. Your body needs a break to heal. While taking time off from exercise is recommended, if you just can?t ditch all physical activities, switch to more low-impact ones while you?re recovering. When resting your Achilles, try biking, swimming or using an elliptical machine until you?re fully healed. Icing the injured area of your Achilles tendon throughout the day can help to reduce the swelling and pain. However, try not to ice it for more than 20 minutes at a time. Non-steroidal anti-inflammatory medication is recommended to help reduce the swelling and pain associated with Achilles tendonitis. These include such drugs as ibuprofen and naproxen. While they will reduce swelling, the do not reduce the thickening for the tendon. If you find yourself taking these medications for more than a month, speak with your doctor.
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.
A 2014 study looked at the effect of using foot orthotics on the Achilles tendon. The researchers found that running with foot orthotics resulted in a significant decrease in Achilles tendon load compared to running without orthotics. This study indicates that foot orthoses may act to reduce the incidence of chronic Achilles tendon pathologies in runners by reducing stress on the Achilles tendon1. Orthotics seem to reduce load on the Achilles tendon by reducing excessive pronation,
