Tendon injuries can be caused by a sudden stress or trauma and also by untreated inflammation and degeneration.
The tendons perform a very important function within the body, connecting the ends of the muscles to the bones. Unlike the muscles, the tendons degenerate very slowly and if severely damaged, may not degenerate at all.
Of the numerous tendons in the foot, the Achilles tendon is the most frequently ruptured.
Other tendons such as the peroneal tendons can be injured but unlike the Achilles they are more prone to splitting than rupturing completely. Such injuries often require surgical repair.
