Because the procedure was to be done via laparoscopy, Florimon might miss only two weeks before resuming baseball activities.
"We'll see how that goes, but it sounds like it's going to be arthroscopic, so hopefully he'll only be a couple weeks before he's back doing some things," Twins assistant general manager Rob Antony told MLB.com. "It wasn't ruptured or anything, but it was inflamed so they're going to remove it."
Manager Ron Gardenhire told MLB.com he expects Florimon to be ready for Opening Day.
"[Florimon's] our shortstop," Gardenhire said. "[Jason] Bartlett is here to try and make the club, but Florimon is our shortstop."
Florimon, 27, hit .221 with nine home runs and 44 RBIs in 134 games with the Twins last season.
