Laurie plays grumpy protagonist Dr. Gregory House on the TV drama and his character uses a cane to walk.
But the fake injury has started to cause Laurie real pain, and he recently sparked rumours he was prepared to sacrifice his job for the sake of his health.
He said, "The show might last through to series seven, eight or nine but I don't know if I will because I'm starting to lose my knees. It's a lot of hip work. There are things going badly wrong."
However, Laurie, 50, insists he's not quite ready to hang up his stethoscope after six seasons as Dr. House.
His representative assures fans reports of his retirement are "not true" and laughs off claims of his hip trouble, branding them "hysterical".
