Just mentioning a ruptured Achilles tendon would make anyone wince. Tendon injuries are well known for their lengthy, difficult and often incomplete healing processes. Sudden or repetitive motion, experienced by athletes and factory workers, for example, increases the risk of tears or ruptures in the tendons; thirty percent of all people will have a tendon injury, with the risk being highest in women. What’s more, those who suffer from these injuries are more prone to further injuries at the site or never recover fully.
