Causes of Achilles Tendinitis Rupture

Achilles tendinitis rupture occurs when the Achilles tendon, which connects the calf muscles to the heel bone, is torn or ruptured. There are several factors that can contribute to the development of this condition.

Overuse and repetitive strain

One of the main causes of Achilles tendinitis rupture is overuse and repetitive strain on the tendon. This occurs when the tendon is subjected to excessive stress or pressure over a prolonged period of time. This can happen in individuals who engage in activities that involve repetitive jumping, running, or lunging motions, such as athletes or dancers. The constant strain on the tendon can eventually weaken it, making it more susceptible to rupture.

Age-related degeneration

As we get older, our tendons naturally become weaker and more prone to injury. This is known as age-related degeneration. The Achilles tendon is no exception to this process. With age, the tendon loses some of its elasticity and strength, making it more susceptible to rupture. This is why Achilles tendinitis rupture is more common in individuals over the age of 30.

Sports and physical activities

Participating in certain sports or physical activities can increase the risk of Achilles tendinitis rupture. Sports that involve quick, explosive movements, such as basketball, tennis, and soccer, put a lot of strain on the Achilles tendon. Additionally, activities that require sudden changes in direction or intense jumping can also contribute to the development of this condition.

Improper footwear

Wearing inappropriate footwear can also contribute to the development of Achilles tendinitis rupture. Shoes that do not provide proper support or cushioning can increase the stress and strain on the Achilles tendon. Additionally, shoes that do not fit properly or have worn-out soles can also contribute to the development of this condition.
