Three-time grand slam champion Andy Murray has undergone hip surgery and is determined to return to action in time for this year’s Wimbledon.

The 30-year-old Briton, who has not played a competitive match for six months and last week withdrew from the Australian Open, posted an update on Facebook.

“Today I underwent successful right hip surgery at the St Vincent Hospital in Melbourne,” Murray said.

“I’d like to thank Dr John O’Donnell and all of the staff for looking after me. I look forward to returning to competitive tennis during the grasscourt season.

“Thanks to everyone for all the well wishes and support over the last few days. I’ll come back from this.”

Murray, though, accepts he will have to reduce his workload on court.

“I’m certainly not going to be putting in the same amount of tournaments and effort to try to get to No. 1,” he told British media. “I’ll certainly be more considered in the amount of tournaments I play, even though I play a conservative schedule anyway in comparison to most of the players on the tour.

“I’ll be playing a reduced schedule, and then focusing more on trying to win major events and big tournaments rather than trying to achieve certain ranking goals.”

Murray said he can get himself back to “95 per cent of my best.”

“I believe that’s enough to compete at the highest level,” he added. “No question.”

Murray, who ended 2016 as world No.1, has slipped to 19th in the rankings.
