The 34-year-old club Washington Capitals announces this on Twitter.
“Bäckström will begin his rehabilitation and long recovery process immediately,” Washington writes.
Bäckström operated on the same hip in 2015 but has had recurring problems afterwards. He missed the start of last season due to hip problems and was not back in action until December.
In the end, there were 47 regular season matches and 31 points (6 + 25) for Bäckström.
