Why Is Courteney Cox Walking With A Cane??

This is an odd sight!
Courteney Cox was spotted walking around with a cane on the Cougar Town set on Thursday.
Is it for a CT storyline??
Turns out, Courteney recently underwent minor knee surgery, but is already back to work! Producers say that the cane will even be written in of of the episodes.
What a trooper!
Get better, hon!
