Director Wes Craven is back on his feet, three weeks after undergoing knee replacement surgery.

The Scream filmmaker checked into hospital earlier this month in a bid to have joint problems in his right leg fixed and he spent the holidays hobbling around on crutches.

But Craven reveals he's making a fast recovery and can now walk almost unaided.

In a Twitter.com post on Tuesday, he writes, "Knee update: Today's my 3 week anniversary, and I'm off crutches and on just a cane or nothing! Things That Make Me Smile."
