At the age of 31, Krantzcke died from a heart attack while jogging.

Krantzcke, a tall right-handed player, achieved much junior success including winning the Australian junior singles title in 1966.

Her most successful season came in 1969/70. After reaching the US Open quarterfinals, she reached the semifinals at the Australian Open and the French Open and then reached the quarterfinals at Wimbledon. At these tournaments, she upset highly ranked players like Virginia Wade, Françoise Dürr, and Judy Tegart Dalton.

During this time, she also combined with Dalton to win the Federation Cup for Australia, remaining undefeated in singles and doubles on the German clay.

After Wimbledon in 1970, 'Kran' took eighteen months off the tour after discovering she was hypoglycemic.

On returning to the tour, she was never able to get back to her best form. She continued to do well in her home Australian championship and reached the semi-finals for the second time in 1977. During her career she defeated Margaret Court, Evonne Goolagong Cawley four times, Billie Jean King twice, Kerry Melville Reid four times, and Virginia Wade. At the New South Wales Open in 1974 Krantzcke defeated Evonne Goolagong Cawley in the final 6–2, 6–3 and at Strathfield in 1969 she defeated Evonne Goolagong Cawley in the final 6–3, 6–4.

While playing on the Challenger circuit in the US in 1977, Krantzcke suffered a heart attack while jogging. In response to her untimely death, the WTA instituted the Karen Krantzcke Sportsmanship Award which is still awarded annually to a female professional tennis player.

A street in the Canberra suburb of Nicholls, Australian Capital Territory, Krantzcke Crescent, is named after the tennis star.

Krantzcke played twice in Federation Cup for Australia; in 1966 and 1970. She also represented Australia in the Bonne Bell Cup in 1974.
