Achilles tendinitis is an inflammation of your Achilles tendon. It?s quite common in people who have psoriatic arthritis, reactive arthritis or ankylosing spondylitis. It can also occur as an over-use injury in people who take part in excessive exercise or exercise that they?re not used to.
Achilles tendinitis is caused by repetitive or intense strain on the Achilles tendon, the band of tissue that connects your calf muscles to your heel bone. This tendon is used when you walk, run, jump or push up on your toes. The structure of the Achilles tendon weakens with age, which can make it more susceptible to injury – particularly in people who may participate in sports only on the weekends or who have suddenly increased the intensity of their running programs.
In most cases, symptoms of Achilles tendonitis, also sometimes called Achilles tendinitis, develop gradually. Pain may be mild at first and worsen with continued activity. Repeated or continued stress on the Achilles tendon increases inflammation and may cause it to rupture. Partial or complete rupture results in traumatic damage and severe pain, making walking virtually impossible and requiring a long recovery period. Patients with tendinosis may experience a sensation of fullness in the back of the lower leg or develop a hard knot of tissue (nodule).
To confirm the diagnosis and consider what might be causing the problem, it?s important to see your doctor or a physiotherapist. Methods used to make a diagnosis may include, medical history, including your exercise habits and footwear, physical examination, especially examining for thickness and tenderness of the Achilles tendon, tests that may include an x-ray of the foot, ultrasound and occasionally blood tests (to test for an inflammatory condition), and an MRI scan of the tendon.
NSAIDS like ibuprofen are often prescribed to help manage the pain and inflammation. Steroids are often recommended when patients do not respond to NSAID treatment. They are often most effective when injected directly into the inflamed and swollen area. Physiotherapy is a great way to stretch and strengthen the Achilles tendon. A good physical therapist will also teach the patient techniques which give better foot support during exercise (taping, wrapping, etc?). Orthotics, assistive devices and insoles can be used to cushion and cradle the arch of the foot during the healing process. Shock Wave Therapy. This is the newest form of treatment and uses concentrated sound waves to stimulate healing in the affected area. This form of treatment is reserved for heel pain that is unresponsive to other forms of treatment.
Open Achilles Tendon Surgery is the traditional Achilles tendon surgery and remains the ‘gold standard’ of surgery treatments. During this procedure one long incision (10 to 17 cm in length) is made slightly on an angle on the back on your lower leg/heel. An angled incision like this one allows for the patient’s comfort during future recovery during physical therapy and when transitioning back into normal footwear. Open surgery is performed to provide the surgeon with better visibility of the Achilles tendon. This visibility allows the surgeon to remove scar tissue on the tendon, damaged/frayed tissue and any calcium deposits or bone spurs that have formed in the ankle joint. Once this is done, the surgeon will have a full unobstructed view of the tendon tear and can precisely re-align/suture the edges of the tear back together. An open incision this large also provides enough room for the surgeon to prepare a tendon transfer if it’s required. When repairing the tendon, non-absorbale sutures may be placed above and below the tear to make sure that the repair is as strong as possible. A small screw/anchor is used to reattach the tendon back to the heel bone if the Achilles tendon has been ruptured completely. An open procedure with precise suturing improves overall strength of your Achilles tendon during the recovery process, making it less likely to re-rupture in the future.
Regardless of whether the Achilles injury is insertional or non-insertional, a great method for lessening stress on the Achilles tendon is flexor digitorum longus exercises. This muscle, which originates along the back of the leg and attaches to the tips of the toes, lies deep to the Achilles. It works synergistically with the soleus muscle to decelerate the forward motion of the leg before the heel leaves the ground during propulsion. This significantly lessens strain on the Achilles tendon as it decelerates elongation of the tendon. Many foot surgeons are aware of the connection between flexor digitorum longus and the Achilles tendon-surgical lengthening of the Achilles (which is done to treat certain congenital problems) almost always results in developing hammer toes as flexor digitorum longus attempts to do the job of the recently lengthened tendon. Finally, avoid having cortisone injected into either the bursa or tendon-doing so weakens the tendon as it shifts production of collagen from type one to type three. In a recent study published in the Journal of Bone Joint Surgery(9), cortisone was shown to lower the stress necessary to rupture the Achilles tendon, and was particularly dangerous when done on both sides, as it produced a systemic effect that further weakened the tendon.
