Things began well for Rossana in 2005, starting with a semifinal appearance in Waikoloa. However, a knee injury kept her out of play from February to October. Upon her return to the ITF circuit, Rossana had fallen over 100 positions on the WTA rankings- from No. 186 to 289. In her return tournament, she impressively reached the semifinals of Pelham, Alabama. In October, she reached the quarterfinals of San Francisco. She won nine matches out of sixteen for the year.

Ranked as low as No. 452, she came through in qualifying, winning seven consecutive matches en route to the final. She was defeated by Edina Gallovits despite Rossana leading 5–0 in the final set and having six match points. Despite the loss, next week Rossana went on to reach the final in Palm Beach Gardens, beating the eighth, fourth and second seeds respectively, before losing in the final. In July she qualified for Cincinnati (Tier III) but lost to world number 26 (at the time) Katarina Srebotnik, after serving for the set at 5–3 in the second set. She reached the quarterfinals in Lexington, Kentucky later in the month, but lost to Stéphanie Dubois, despite leading 4–2 in the final set. She fell in the first round qualifying of the US Open to Erika Takao, in what was her first Grand Slam qualifying match in two years.

Fresh from victory, Rossana quickly flew to Paris for the first time since 2004 to compete in the qualification event of Roland Garros. She caused a stir by easily qualifying, easily winning three straight sets matches. She lost to the 32nd seeded Martina Müller in straight sets in the first round.[2]. Her next tournament was the $75K Přerov, where she reached the quarterfinals in singles, before losing to Sofia Arvidsson in straight sets, and reached the doubles final with her partner Edina Gallovits, where they lost to top seeds in three sets.
