“It’s just not the way to go forward so unfortunately for the medium-to-long term to feel better I will need surgery.
“I decided to do it. I will be on crutches for many weeks and then out of the game for many months.”
Murray has also had his own setbacks this year, being forced to pull out of the men’s singles event in Tokyo after tearing his quad muscle, though he continued to play in the men’s doubles with Joe Salisbury.
“It was hard and frustrating to have to miss the opportunity to play in another big event again. It was tough because I obviously felt like I had built up some sort of momentum during Wimbledon,” he said.
Speaking ahead of his opening round in Cincinnati, where he will face a qualifier from the strong field of winners who came through, he said: “Since then I have been back and practising and building up. I arrived nice and early on the Monday and have just been preparing since.”
