Paletta joined Boca Juniors at the start of the 2007/08 season. He helped Boca reach the semi-final of the 2008 Copa Libertadores, where the Buenos Aires club lost 5-3 on aggregate to the Brazilians from Fluminense. In July 2010 Paletta left for Italian Serie A club Parma. The Argentinian was clearly more ready now than four years earlier to leave his homeland. He has become a firm fixture in the middle of Parma's defence, making over 100 appearances in three years. Paletta was so impressive that the Italian national team utilised the fact that his great-grandfather, Vicenzo, was born in Crotone, Calabria before he emigrated to Argentina. Paletta made his international debut for Italy in a 1-1 friendly against Spain on 5 March 2014 and played against England in the World Cup in Brazil.
The Argentinian defender played in Serie A 21 times for Parma in the 2013/14 season and added two more appearances in the Coppa Italia. Parma's 6th place finish in the league ought to have seen them qualify for the Europa League Third Qualifying Round. But that place went instead of 7th placed Torino because UEFA refused to give Parma a licence because of an overdue tax debt. With Parma imploding financially, he was sold to AC Milan at the end of the January 2015 transfer window and then loaned to Atalanta for 2015/16, where he played 24 times scoring once.
For 2016/17 Paletta was back with AC Milan and a regular in central defence. However in 2017-18 he was out of favour and played just once, in the Europea League, before moving to Chinese Super League side JS Suning in January 2018. He played 24 times in the league for them in the 2018 season, scoring once and remained there for a second year in 2019.

"Paletta is very tough and he's exactly the sort of player we need who will suit the Premiership. When you talk about the Argentinean defenders I worked with in Valencia, Paletta is more like Roberto Ayala than Mauricio Pellegrino. If you're talking about Liverpool, he's more like Jamie Carragher than Sami Hyypia. This is good because we will have a balance in the style of defenders."
