(Pl. Fabellae)

A small accessory bone that is present in the knee joints of roughly 1/3 of individuals. Its exact function or purpose, if indeed it has one, is not known, although the fabella has been associated with a number of knee-related problems.

The bone is so called because, as its Latin-derived name might suggest, it resembles a little bean.

Much as Michael revelled in people's deep-seated disgust for him and always went to lengths to make himself as filthy, grotesque, and loathsome for others as possible, his signature limp and twitchiness- when he wasn't massively exaggerating these things- stemmed mostly from a fabella in his right knee that interfered constantly with various nerves in his leg
