In April 2017, Medvedeva competed on Team Russia at the 2017 World Team Trophy held in Tokyo, Japan. She placed first in the short program with a new world record score of 80.85, becoming the first female skater to break the 80-point mark for the ladies' short program score. She placed first again in the free skate with another world record score of 160.46, becoming the first female skater to break the 160-point mark for the ladies' free skating score. Medvedeva contributed the maximum 24 points and helped Team Russia win their second consecutive silver medal while Team Japan and Team USA won gold and bronze respectively. Even though the combined total score was not given at the event, ISU later ratified her combined world record total score of 241.31; thus, Medvedeva became the first female skater to break the 240-point mark in the combined total score. She stated, "I went out on the ice absolutely calm, there was no shadow of a doubt or lack of confidence in me.”
