In House M.D., which episode reveals the story behind House’s leg injury?

“Three Stories” reveals the story behind House’s leg injury in House M.D.

The episode is the season-one installment “Three Stories,” which aired in May 2005. Its structure follows House teaching medical students while presenting three apparently separate diagnostic cases. The unusual format lets the episode explore how doctors interpret symptoms, evidence, and uncertainty.

The final story explains that House suffered an infarction in the quadriceps muscle of his right thigh. The injury caused permanent damage and chronic pain, leading to his dependence on a cane and Vicodin. Stacy Warner, House’s former partner, becomes part of the account because she made a difficult decision about treatment while House was incapacitated.

“Three Stories” is frequently singled out as one of the series’ most important early episodes. It won the Primetime Emmy Award for Outstanding Writing for a Drama Series, making it a notable example of the show’s blend of medical mystery and character history.
