Amid the slew of injuries that have taken place within the roster, the Boston Celtics cornerstone, Kyrie Irving, might need “maintenance surgery” on his bothersome left knee during the next few years, according to president Danny Ainge per Jared Weiss of CelticsWire.

Irving has missed several games this season to tend to his sore knee, including a double-overtime thriller against the Washington Wizards last night.

Joe Vardon of Cleveland.com had reported that Irving was in need of this cleanup procedure after he had threatened to sit out the season with this same surgery if the Cleveland Cavaliers didn't trade him prior to the start of this season. A method that worked wonders for the All-Star guard upon his arrival in Boston.

Ainge said the team was very much aware of his knee situation upon trading for him, but it could be something manageable with the right monitoring.

The injury stems from the time Irving fractured his kneecap in Game 1 of the 2015 NBA Finals and had season-ending surgery to repair it. The lingering knee soreness is caused by tendinitis from the wear and tear post-procedure, a reason why the Celtics have shut him down for the rest of the week, with a No. 2 seed likely locked up.

Irving’s surgery is likely to be minor in nature, a non-invasive procedure to clean up scar tissue, alleviating the discomfort of the tendinitis, at which point he will have to work on strengthening the joint once again as he gears for another season.
