The 65-year-old 'Bat Out of Hell' singer underwent a knee replacement procedure in November and has spent months undergoing gruelling physiotherapy treatment in time to be ready for his UK tour, which kicks off later this week.
However, Meat Loaf has now revealed he is facing further surgery because his other knee also needs replacing, reported Contactmusic.
"I've had a knee replacement. I've got to have the other one replaced," he said.
Meat Loaf said that it will take him around a year to fully recover from the first operation.
