gnarled - twisted
Something ‘gnarled’ is rough and twisted, typically due to old age or prolonged exposure to bad weather. This term is most commonly used in relation to an old tree that is full of knots and lumps, and a person showing signs of their advanced age on their skin or in the shape of their body. It can also be used in a more figurative sense to refer to somebody who is considered a tough veteran of something.
