Courteney Cox has a new accessory of sorts.

The Cougar Town star was spotted walking around the set of her ABC show Thursday with the help of a cane.

So what’s up? Cox, it turns out, has a bum knee thanks to a recent surgery.

“The minor knee surgery was planned,” a rep for the actress tells PEOPLE. “[The cane] will be written into one episode of Cougar Town but will not affect the production schedule at all.”

The show, which is in production but currently on hiatus, will return to ABC for a special post-Dancing with the Stars episode April 18 (9:30 p.m. ET) and will be back on at its regular timeslot (Wednesdays at 9:30 p.m. ET) two days later.

“[Cox is] working every day,” according to a source, who adds that the series will wrap in Los Angeles the first week of March, then the cast will go to Hawaii to shoot the season finale, which will air in May.
