The king was recovering "better than expected" after a surgeon on Tuesday fitted a temporary replacement for an implant that had got infected, his eighth operation in just over three years, the Quiron Hospital in suburban Madrid said in a statement.
The monarch was able to get up and take several steps in his hospital room, and remained seated for a short period on yesterday, the statement said.
"During the current day it is expected that he will begin to walk in his room with the aid of a walker," it added.
The monarch will need a new operation to receive a permanent prosthetic hip after at least eight weeks fighting off the infection in the surrounding tissue, the surgeon added at a press conference held Tuesday after the surgery was completed.
He predicted Juan Carlos could be up and walking about six weeks after he finally receives the permanent implant.
News that a further operation would be needed after two months to insert a permanent implant kept alive speculation of a possible abdication in favour if his 45-year-old son Felipe, despite palace denials.
