Asked if he would need to be careful if he played for England against Estonia on Saturday, he told Sky Sports News: "Not at all.
"No doubt the manager from here will say that and maybe the fans will say that but if I had to look after myself, I wouldn't have made myself available for today.
"The surgeon's advice is what I'll look at more than anything else and she said that I can push it as hard as I want - it's stronger now than it was before the operation."
Owen even thought he should have started against Everton instead of playing just 16 minutes after coming on as a substitute for Nigeria international Obafemi Martins.
The 27-year-old added: "To play a game eight days after surgery - I've still got the stitches in - I've put in a lot of hard work.
"I was disappointed not to start, I've been training fully since Thursday
"I've not missed much training and I felt ready to start but the manager obviously wanted to leave me out and bring me on from the bench."
