Akillesjänne

Akillesjänne, also known as the Achilles tendon, is a strong fibrous cord that connects the muscles in the back of the calf to the heel bone. This tendon is crucial for locomotion, enabling actions such as walking, running, and jumping by transmitting the force from the calf muscles to the foot.

The Achilles tendon is the largest tendon in the human body and is composed primarily of collagen. Its tensile strength is remarkable, but it is also susceptible to injury due to its location and function. Common injuries include tendinitis, which is inflammation of the tendon, and tendinosis, which involves degeneration of the tendon tissue. These conditions often result from overuse, sudden increases in activity, or improper footwear.

The most severe injury is an Achilles tendon rupture, where the tendon tears completely or partially. This typically occurs during sudden, explosive movements, such as sprinting or jumping, particularly in individuals who are not accustomed to such physical exertion. A rupture often presents with a sudden, sharp pain in the back of the ankle and a feeling or sound of snapping. Surgical intervention is often required for complete ruptures, followed by a lengthy rehabilitation period.

Prevention strategies for Achilles tendon injuries include regular stretching of the calf muscles, gradual progression of exercise intensity, and wearing appropriate footwear that provides adequate support. Strengthening exercises for the calf muscles can also help to improve tendon resilience.
