The Brooklyn Nets professional basketball player, Allen Crabbe has not played since December 12, 2018  due to a right knee injury that occurred during a game against the Philadelphia 76ers. His right leg got tangled with 76ers center Amir Johnson, while taking a shot.  This knee injury was particularly frustrating to Allen, given that  it occurred during his first game after coming back from a left ankle sprain that  occurred in the pre-season.

It’s difficult to tell from media reports what the problem is with his knee.  One report described it as inflammation of a “fat pad”, but that’s not a common knee injury or diagnosis.

Media reports describe removal of the “excess fluid” out of his swollen right knee. There is almost never a good reason for doing this.  It’s difficult to make sense of what is going on.

Adding to the puzzlement, according to his coach, Crabbe will not have  surgery.

It is not clear how many more games Allen will be missing and whether he will be back any time this season.
