The Red Sox announced that Dustin Pedroia underwent a fifth knee surgery — this one a joint preservation procedure — Tuesday in Vail, Colo. The operation was performed by Dr. Matt Provencher at the Steadman Clinic. Pedroia will begin his rehabilitation in Arizona.
Dr. Christopher Geary, an orthopedic surgeon at Tufts Medical Center who has not treated Pedroia, described this type of operation as “a much bigger procedure’’ than anything Pedroia has had to this point.
“If he was 16, they do either knee replacement or a partial knee replacement,’’ said Geary. “But because of his age , there’s a relatively newer technique where they take what’s called a mega allograft. They take it from a cadaver and plug it in where the cartilage is no good.
“It’s a day-to-day-life procedure; it’s not a going-back-to-playing-sports procedure.
“It’s not compatible with playing high-impact sports.’’
Pedroia was placed on the 60-day injured list May 27 after struggling through a rehab assignment. In 11 games between Triple A Pawtucket and Double A Portland, the second baseman batted .189 (7 for 37) with no extra-base hits, one RBI, one walk, and seven strikeouts before pain in his knee forced him to the injured list again.
Since the end of the 2017 season, Pedroia has played in only nine major league games.
