Ramsey became the third Gunners players to break his leg in five seasons after he was on the receiving end of a strong tackle from Stoke City's Ryan Shawcross last weekend.
Croatia striker Eduardo and fellow midfielder Abou Diaby have also been stricken by serious injury and Rosicky has urged referees to be more vigilant after claiming the Gunners regularly fall victim to heavy-handed tactics from opposing teams.
"I think you cannot blame the player (Shawcross) or to tell that he wanted to break his leg, of course not," Rosicky told Sky Sports News.
"But it's always against us. The teams operate aggressively against us, that's no problem for us, I think everybody copes with that but I think we have to be more protected from the referees.
"Because if you see, for example, how many fouls the opponents can do against us, five, six and after that it's a yellow card.
"We are making one or two fouls and we've got immediately yellow cards.
"So we have to be more protected as well."
