Mechanism on Injury
There are a few ways that an Achilles tendon rupture can occur.
One way would be as shown in the picture to the immediate left. This type is called acute force trauma. Rarely do we see examples in normal life of someone actually cutting your Achilles tendon.
The most common mechanisms of injury include sudden forced plantar flexion of the foot, unexpected dorsiflexion of the foot, and violent dorsiflexion of a plantar flexed foot. Other mechanisms include direct trauma and, less frequently, attrition of the tendon as a result of longstanding peritenonitis with or without tendinosis.
