What caused Dr. Gregory House’s permanent limp in House, M.D.?

A quadriceps muscle infarction caused Dr. Gregory House’s permanent limp in House, M.D.

Before the series begins, a blood clot cuts off circulation to part of the quadriceps muscle in House’s right leg. The resulting muscle death, or infarction, leaves him with chronic pain and a lasting limp. He later relies on a cane and takes pain medication, especially Vicodin, to manage the consequences.

The show reveals the history through flashbacks and conversations rather than presenting it all at once. House initially allowed doctors to amputate, but his former partner Stacy Warner helped arrange a less drastic procedure. Surgeons removed the dead muscle instead, preserving his leg but leaving substantial damage.

The injury is often incorrectly described as a bone fracture or a simple sports injury. It was a vascular problem affecting muscle tissue, and the resulting pain and disability are central to House’s personality and medical outlook. His own experience also shapes his resistance to conventional assumptions about patients.
