In 1995, Lüdemann would win with Köln the German championship after defeating EV Landshut. He would then rise and establish himself as one of the best defencemen of the DEL, playing a reliable game and showing some excellent offensive abilities. He would become German champion a second time in 2002 after a win over the Adler Mannheim.
Lüdemann played in 132 international games for the German National Team before retiring from international competition. He became in 2006 the player with the most games played for the Kölner Haie with 691, thus passing Peppi Heiß.
