Hacknee

Hacknee: noun. A knee with pain that has been caused by overuse. Hacknees are most common amongst footballers, bouncers, seamstresses and anyone who has visited the Burj Dubai when the elevators weren't working. The malady was first identified by famed physician Elizabeth Blackwell, and attesting to the greatness of her life, this discovery was one of the least impressive feats of her career.
