Dr. Peter Asnis performed the procedure at Massachusetts General Hospital.
Buchholz, who pitched six innings in Boston’s final game against the Yankees on Sunday, finished the season with an 8-11 record and 5.34 ERA -- the worst ERA of any starter in the league. According to GM Ben Cherington, Buchholz pitched with the injury during the season.
“This is something that he's had some off-and-on symptoms for some time now,” Cherington said on Sunday. “Not something that prevents him from pitching, but we just want to use the offseason to take care of this. It's a relatively routine procedure. Pretty quick recovery, shouldn't affect his offseason."
Cherington maintained that the meniscus issue had no impact on Buchholz's performance.
"It was not a debilitating issue," Cherington said. "It was something that he managed. I think he would tell you that it did not affect him. We're just trying to be proactive so that it doesn't turn into something bigger."
