Manilow had surgery to remove fluid and repair torn muscles in his hips. He will be in recovery for six weeks and plans to return to the stage in early February.
The 68-year-old entertainer waited until he performed his 1,000th Las Vegas concert and ended his seven-year run at two resorts there before having the surgery.
Manilow had hip surgery the first time back in 2006.
