Dodgers reliever Hong-Chih Kuo will undergo surgery on his left elbow for the fifth time in his career on Friday, this time an arthroscopic procedure to remove a loose body. The procedure normally is considered a minor one, and Kuo is expected to be at full strength by the start of spring training. "(But) it's never a minor procedure if it is attached to the elbow of Kuo,'' Dodgers medical-services director Stan Conte said. "We don't expect it to be a big deal, but you kind of hold your breath when it's a surgery involving Kuo.''
