Wall is expected to miss six weeks and will not play in next month's NBA All-Star Game.
The surgery will be performed by the head team physician for the Cleveland Cavaliers, Dr. Richard D. Parker, the same specialist who performed Wall's double knee procedure in May 2016, and with whom he consulted for his November treatment.
So just how bad is this for the Wizards? Those numbers are all down from a season ago.

That put the pressure on the Thunder to score, but they were unable to. It looks like (yet again), a team only needs to stay a game or two above.500 to make the playoffs in the East.
The 29-year-old Love has missed only one game this season, and he's the Cavs' second-leading scorer behind LeBron James.
Moving forward, Adam Silver will need to replace Wall in the All-Star Game (as he did Cousins with Paul George). Wall's absence simply isn't going to help matters.
With Wall sidelined, the Wizards are exceptionally thin at point guard. Regardless of record, having Wall and Beal makes the Wizards a unsafe team that should never be overlooked. Moreover, with the trade deadline just ten days away and the Wizards having little wiggle room with salary it could be a tricky prospect for the Wizards brain trust.
The team has boasted one of the more consistent starting units in the National Basketball Association.
Yet the Wizards' remaining schedule features opponents that boast a composite 55% winning percentage, the most hard of any team in the Eastern conference.
It's ironic that the Wizards' main goal right now is to maintain their play while Wall is out, because most people watching them understand maintaining their play means losing early in the playoffs again.
