The Achilles tendon is the tendon that attaches the gastrocnemius (calf muscles) to the calcaneus bone (back of the heel). It is important in activities that involve plantar
flexion of the ankle (pushing down with the foot or doing heel raises). The Achilles tendon can get inflamed (tendinitis) or it can degenerate/wear out (tendinopathy) with repetitive activities.
Aggravating activities include running and/or repetitive jumping.
The majority of Achilles tendon injuries are due to overuse injuries. Other factors that lead to Achilles tendonitis are improper shoe selection, inadequate stretching prior to engaging in athletics,
a short Achilles tendon, direct trauma (injury) to the tendon, training errors and heel bone deformity. There is significant evidence that people with feet that role in excessively (over-pronate) are
at greater risk for developing Achilles tendinitis. The increased pronation puts additional stress on the tendon, therefore, placing it at greater risk for injury.
Patients with an Achilles tendon rupture frequently present with complaints of a sudden snap in the lower calf associated with acute, severe pain. The patient reports feeling like he or she has been
shot, kicked, or cut in the back of the leg, which may result in an inability to ambulate further. A patient with Achilles tendon rupture will be unable to stand on his or her toes on the affected
side. Tendinosis is often pain free. Typically, the only sign of the condition may be a palpable intratendinous nodule that accompanies the tendon as the ankle is placed through its range of motion
(ROM). Patients with paratenonitis typically present with warmth, swelling, and diffuse tenderness localized 2-6 cm proximal to the tendon's insertion. Paratenonitis with tendinosis. This is
diagnosed in patients with activity-related pain, as well as swelling of the tendon sheath and tendon nodularity.
X-rays are usually normal in patients with Achilles tendonitis, but are performed to evaluate for other possible conditions. Occasionally, an MRI is needed to evaluate a patient for tears within the
tendon. If there is a thought of surgical treatment an MRI may be helpful for preoperative evaluation and planning.
The initial aim of the treatment in acute cases is to reduce strain on the tendon and reduce inflammation until rehabilitation can begin. This may involve, avoiding or severely limiting activities
that may aggravate the condition, such as running or uphill climbs. Using shoe inserts (orthoses) to take pressure off the tendon. Wear supportive shoes. Reducing Inflammation by icing. Taking
non-steroidal anti-inflammatory drugs. Heel cups and heel lifts can be used temporarily to take pressure off the tendon, but must not be used long term as it can lead to a shortening of the calf.
Calf Compression Sleeves. Placing the foot in a cast or restrictive ankle-boot to minimize movement and give the tendon time to heal. This may be recommended in severe cases and used for about eight
Surgery is considered the last resort. It is only recommended if all other treatment options have failed after at least six months. In this situation, badly damaged portions of the tendon may be
removed. If the tendon has ruptured, surgery is necessary to re-attach the tendon. Rehabilitation, including stretching and strength exercises, is started soon after the surgery. In most cases,
normal activities can be resumed after about 10 weeks. Return to competitive sport for some people may be delayed for about three to six months.
Your podiatrist will work with you to decrease your chances of re-developing tendinitis. He or she may create custom orthotics to help control the motion of your feet. He or she may also recommend
certain stretches or exercises to increase the tendon's elasticity and strengthen the muscles attached to the tendon. Gradually increasing your activity level with an appropriate training
schedule-building up to a 5K run, for instance, instead of simply tackling the whole course the first day-can also help prevent tendinitis.
