Pop superstar Lady Gaga feared her stage career would be over if she failed to bounce back from hip surgery earlier this year (13). The Born This Way hitmaker was forced to scrap the remainder of her world tour in February (13) after she was diagnosed with the condition synovitis, an inflammation of the joints, and a labral tear. She recently revealed she had actually broken her hip during the trying time and faced a complete hip replacement if she didn't heed doctors' advice to axe her shows and immediately go under the knife. Now Gaga admits her health problems were so serious, it could have spelled the end of her performing career. She tells the BBC, "I think the fear was more before (surgery) that I would never be able to do this again. I was nervous, sure. I mean, when the tour ended, I love my fans more than anything, I love making music and I surely love being a star for everyone, but I more love being an entertainer." The singer admits she wasn't a model patient as she recovered from the setback, but the forced rest did her the world of good: "I was really good at rehab. I really focused and I worked really hard. Even when I was in my wheelchair, sitting at home, I wanted to dance, I wanted to perform, I wanted to sing, I wanted to go out and write music, I wanted to go see things for inspiration, so yeah, they (doctors) had to kind of strap me down a bit (to make me rest), but it was good for me, it was really good for me. I needed that; sometimes God forces you to stop." Gaga made her big stage return at the MTV Video Music Awards in New York last month (Aug13) and performed her first full concert comeback in London on Sunday (01Sep13), but she admits her body is still adjusting to her rigorous dance routines. She says, "I'm reawakening my muscles. I'm dancing the same way I've always danced and going in with no fear, but I can feel my muscles sort of spasming and waking up as I'm dancing and it's kind of exciting. I feel like Frankenstein!"
