Cape Town - Andy Murray has revealed that he asked the royal family's surgeon about her credentials, prior to going under the knife to repair a persistent hip injury.
Writing in his BBC Sport column, Murray said that Sarah Muirhead-Allwood was the doctor that he chose to entrust both his career and his comfort to.
And, after declaring himself pain-free and ready to return at Queen's this week, it appears to have been a good decision.
"I knew she had operated on Prince Philip's hip last year and before that on the Queen Mother but I didn't know how that would translate to working on an athlete," Murray said.
"I asked her 'how do I know you're good?' I wasn't doing it to be rude but, in sport, you can tell how good someone is by their ranking.
"But how I do know a surgeon is good? She just said to me 'well, you don't'.
"She was very honest and I admired that. She didn't promise I would get back to playing.
"I didn't want to have someone telling me 'you'll definitely be back and winning Wimbledon in five months' because it wouldn't have been true."
