In House M.D., which character uses a cane because of a leg injury?

Gregory House uses a cane because of a leg injury in House M.D.

House suffers chronic pain and impaired mobility after an infarction in the quadriceps muscle of his right leg. The injury leads to extensive tissue damage, and he relies on a cane while taking medication to control severe pain.

The cane is one of the character’s most recognizable visual details, but it also has a medical and dramatic purpose. House’s physical disability affects his daily life, contributes to his dependence on pain medication, and shapes how he relates to patients experiencing chronic illness.

The show later depicts changes in House’s treatment and pain-management choices. Those storylines should not be confused with the original cause of his limp: the infarction and resulting damage occurred before the main events of the series.
