She currently holds four Guinness World Records, the fourth in recognition of her landed quadruple flip at the 2019 ISU Grand Prix Final.

[26] Trusova debuted internationally in August 2017 at a 2017–18 ISU Junior Grand Prix (JGP) competition in Brisbane, Australia.

Ranked first in both the short program and free skate, she won the gold medal ahead of teammate Anastasia Gulyakova.

Her total score of 197.69 points was the third highest ever achieved by a women's single skater on the junior level at the time, behind only Alina Zagitova and Marin Honda.

[30] In January 2018, Trusova won the gold medal at the 2018 Russian Junior Championships after placing first in the short program and third in the free skate.

[31] In March 2018, Trusova competed at the 2018 Junior Worlds, where she won the gold medal after placing first in both the short program and free skate.

She ranked first in both the short program and the free skate and won the gold medal by 30 points over silver medalist Kim Ye-lim.

Again she placed first in both the short program and free skate, winning the gold medal by 33 points over silver medalist and teammate Alena Kanysheva.

[39] Trusova made her international senior debut at the 2019 CS Ondrej Nepela Memorial, where she won the gold medal and set several new world records.

She earned 14.72 points for her quadruple Lutz, a new record for the highest valued single jump by a female skater which was phenomenal.

Skating in the short program, Trusova opted to attempt the triple Axel in competition for the first time but underrotated it and fell.

On May 6, 2020, it was announced by Russian media outlets Nevasport and Sport24 that Trusova had decided to part ways with coach Eteri Tutberidze in favor of joining Evgeni Plushenko's academy.

[53] At the second stage of the Russian Cup held in Moscow, Trusova made a mistake on her triple Axel jump in the short program and placed third behind Kamila Valieva and Daria Usacheva.

[55] She encountered similar problems in the free skate, falling four times and receiving negative grades of execution on two other jumping passes.

Her final score of 198.93 saw her drop down to fourth place, unprecedented for Trusova in international competition, and her first off-podium finish since the 2017 Russian Junior Championships.

[60] Trusova was selected to compete for the Russian Federation at the 2021 World Championships in March 2021 in Stockholm, where she was considered a favorite to make the podium.

[61] In the short program, Trusova placed twelfth after putting a hand down on her triple Lutz due to overrotation, consequently failing to execute the second part of her jump combination.

[64] Trusova picked music from the American film Cruella for her free program, having watched it three times beforehand and persuading her coaches.

[65] The following week, Trusova competed at the 2021 U.S. Classic at the Skating Club of Boston, where she made mistakes on four out of five planned quads but narrowly took the gold medal over South Korean skater Park Yeon-jeong.

[66] In late October, it was reported that Trusova had suffered a leg injury shortly before the 2021 Skate America, which did not allow her to train at her maximum.

Despite the injury, Trusova decided to compete and placed first in the short program with a personal best of 77.69 and won the free skate by opening with a quad Lutz.

[68] Returning to competition at the 2022 Russian Championships, Trusova placed fifth in the short program after botching her triple Axel attempt.

[76] Trusova opened her fourth senior season at the September 2022 Russian test skate event held in Moscow.

On 1 October, it was reported by TASS that Trusova had again decided to part ways with coaches Eteri Tutberidze, Daniil Gleikhengauz, and Sergei Dudakov, this time in favor of joining Svetlana Sokolovskaya's group at CSKA.

At the fifth stage of the Russian Grand Prix held in Samara, Trusova ranked third in the short program after singling what was intended to be a double axel.

These are trial runs for me, I haven’t decided yet whether I'll come back.” It was announced in October 2024 that Ignatova would not make a comeback in the upcoming competitive season.

An article written by RIA Novosti explained that although Ignatova would continue to train at the Angels of Plushenko Academy, she did not intend to skate competitively during the 2024-2025 season.

Trusova's skating technique is distinguished by her ability to compete with a significant repertoire of quad jumps unrivaled by other female competitors as of 2022.

[13] A few weeks later, she was the first female skater to land a quadruple Lutz jump in international competition, ratified at the 2018 JGP Armenia.
