What Is the Achilles Tendon?
The Achilles tendon runs down the back of the lower leg and connects the calf muscle to the heel bone. Also called the “heel cord,” the Achilles tendon facilitates walking by helping to raise the heel off the ground. It is the largest tendon in the body transmitting and pro-pulsing your entire body weight during walking/climbing stairs and 2-3x your total body weight in running.
Achilles Tendonitis and Achilles Tendonosis
Achilles tendonitis is an inflammation of the Achilles tendon. This inflammation is typically short-lived. Over time, if not resolved, the condition may progress to a degeneration of the tendon (Achilles tendonOSIS), in which the tendon loses its organized structure and is likely to develop microscopic tears. Over time, these microscopic tears evolve into chronic degeneration (with or without pain) which may finally result in partial or complete rupture of the tendon.
As “overuse” disorders, Achilles tendonitis and tendonosis are usually caused by a sudden increase of a repetitive activity involving the Achilles tendon. Such activity puts too much stress on the tendon too quickly, leading to micro-injury of the tendon fibers. Due to this ongoing stress on the tendon, the body is unable to repair the injured tissue. The structure of the tendon is then altered, resulting in continued pain. Athletes are at high risk for developing disorders of the Achilles tendon. Achilles tendonitis and tendonosis are also common in individuals whose work puts stress on their ankles and feet, such as laborers, as well as in “weekend warriors”—those who are less conditioned and participate in athletics only on weekends or rather infrequently. In addition, people with excessive pronation (flattening of the arch) have a tendency to develop Achilles tendonitis and tendonosis due to the greater demands placed on the tendon when walking. If these individuals wear shoes without adequate stability, their over-pronation could further aggravate the Achilles tendon.
The symptoms associated with Achilles tendonitis and tendonosis include:
- Pain—aching, stiffness, soreness, or tenderness—within the tendon. This may occur anywhere along the tendon’s path, beginning with the tendon’s attachment directly above the heel upward to the region just below the calf muscle. Often pain appears upon arising in the morning or after periods of rest, then improves somewhat with motion but later worsens with activity.
- Tenderness, or intense pain, when the sides of the tendon are squeezed.
- When the disorder progresses to degeneration, the tendon may become enlarged and develop nodules in the area where the tissue is damaged.
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.
Treatment approaches for Achilles tendonitis or tendonosis are selected on the basis of how long the injury has been present and the degree of damage to the tendon. In the early stage, when there is sudden (acute) inflammation, one or more of the following options may be recommended:
- Night splints
- Physical therapy
When is Surgery Needed?
If non-surgical approaches fail to restore the tendon to its normal condition, surgery may be necessary. The foot and ankle surgeon will select the best procedure to repair the tendon, based upon the extent of the injury, the patient’s age and activity level, and other factors.
To prevent Achilles tendonitis or tendonosis from recurring after surgical or non-surgical treatment, the foot and ankle surgeon may recommend strengthening and stretching of the calf muscles through daily exercises. Wearing proper shoes for the foot type and activity is also important in preventing recurrence of the condition.[/vc_column_text][/vc_column][/vc_row]
