Pötzsch represented the GDR (East Germany) in the ladies events at international championships. Her first coach was Brigitte Schellhorn.[1] After Pötzsch was admitted into a sports academy, Gabriele Seyfert was assigned as her coach and later, Seyfert's mother, Jutta Müller, took over coaching duties.[1] She was the Olympic Champion in 1980 and world champion in 1978 and 1980. She also won the European title four times, from 1977 to 1980; and the East German title five times, from 1976 to 1980. In 1981, she announced her retirement, saying in 2011, "I had knee problems and I was not motivated because I had reached all my goals" but she said she later regretted her decision.[1]
Pötzsch was a judge at international skating events in the late 1980s but the ISU banned her after she appeared in Skates of Gold shows and Katarina Witt's film, Carmen.[1] The ISU restored her eligibility in 1994, along with that of professional skaters.[1] In the 1990s, Pötzsch worked at a bank but quit her job in 1999 in order to coach.[1] She coaches in Chemnitz, Germany, and in 2004 became an ISU technical specialist.[1] Her students include Daniel Dotzauer, the 2010 German Championships bronze medalist, and Sandy Hoffmann.
