LOS ANGELES (AP) Actor George Hamilton is having his right knee replaced.

His publicist, Jeffrey Lane, said the elective surgery was being performed Thursday in Chicago.

He said the 69-year-old Hamilton first injured his knee while starring in "Chicago" on Broadway, and decided to have his knee replaced after he injured it a second time when he competed on the second season of ABC's "Dancing with the Stars" in 2006.

Hamilton is expected to return to Los Angeles next week.
