"NBC Nightly News" anchor Brian Williams will undergo knee replacement surgery, he announced in an interview Wednesday.

Williams was a guest on "The Late Show with David Letterman" when he announced the procedure, which will repair damage he has dealt with since suffering an injury in a high school football game.

"I'm going in for the knee replacement. I'm going in for the whole titanium thing," he said.

Williams said he has had three prior surgeries since suffering the injury to his right knee in 1977, all of which were unsuccessful. He said the surgeries have left him with arthritis, pins in the knee and a shortened thigh bone.

"I've been living with this leg for a long time, 35 years, so I just want to get it fixed," Williams said.

He told the talk show host and Indianapolis native his left knee is healthy. He did not give a timetable for the surgery.

While the recovery period for the surgery is lengthy, Williams joked about getting back in the anchor chair a little more quickly.

"I want to come back almost a little too early, gooned on medication and I think it will be great viewing," he laughed.

Williams joined NBC News in 1993 and has anchored NBC Nightly News since 2004.
