Former British number one Laura Robson has had hip surgery for a second time "after months of struggling".

The 25-year-old, who first had hip surgery in June 2018, returned to action in February but has not played since retiring during a match in April.

"A decision was made this week to have another hip surgery & try fix the pain for good," Robson posted on Instagram.

"Very much hope to be back on court soon but in the meantime I can't wait to walk my dog without limping."

Her injury issues echo those of former world number one Andy Murray, who in October won his first singles title since having career-saving hip surgery in January.

Robson reached the fourth round at Wimbledon in 2013 and was ranked world number 27 in the same year, but her career has subsequently been plagued by injury.

She had surgery on her wrist in 2014, which kept her out for 17 months, and has suffered with a hip problem in recent years.

Robson has not revealed whether she has undergone the same procedure again, or how long she is expected to be out of action.
