At the 2007 World Championships, Lysacek made his first attempt at landing a quadruple jump in the short program. He attempted a quad-triple, but stepped out of the quad and put his hand down, and followed it with a double. He placed fifth in the short program and earned himself his first new short program personal best in two years. In the long program, he completed a quadruple toe-loop as the first part of a quad-triple combination, but lost control of the landing, adding a three turn after it, and was unable to complete the following triple as intended. He performed a double loop instead of a planned triple loop and placed fifth once again in the long program, placing fifth over all.
