Dr. Steven Shin, the same surgeon who performed Brendan Ryan's late-offseason wrist surgery, operated on Lohse. The right-hander has been bothered by lingering discomfort in his forearm for nearly a year, since first injuring himself when he was hit by a pitch in May 2009.
The procedure, called fascial release surgery, is an unusual one for a baseball player. The Cardinals did not announce any timetable for Lohse's return to baseball, but according to a statement from the club, he will begin physical therapy in about one week.
"This is supposed to be a new and different kind of deal, but I was told with the length of time we're dealing with, it should be before August," manager Tony La Russa said.
