What time does house come on?

What time does house come on? And does anyone know what
Happened to his knee/leg?

I'm not sure what time it comes on - I dont watch it on TV I just own the season's.

Although:

The Muscle Infarction Affliction

A patient: What made you a cripple?
House: I had an infarction.
The patient: A heart attack?
House: It's what happens when the blood flow is obstructed. If it's in the heart it's a heart attack. If it's in the lungs it's a pulmonary embolism. If it's in the brain it's a stroke. I had it in my thigh muscles.
The patient: Wasn't there something they could do?
House: There was plenty they could do, if they made the right diagnosis, but the only symptom was pain. Not many people get to experience muscle death.
The patient: Did you think you were dying?
House: I hoped I was dying. [#101]
