Arsenal crock Per Mertesacker is desperate to make the Euros for Germany.
Mertesacker is out for the season with an ankle injury.
Writing on Facebook, Mertesacker said: "My participation in Euro 2012 is not in danger.
"Dr Stockle in Tubingen did the operation on Tuesday evening, attached a piece of bone back to the ankle and patched up the deltoid ligament on the inside of the ankle.
"All went well and I am in Donaustauf, Bavaria, for the physical rehabilitation."
