Britain's former world number one Andy Murray says he hopes to prove to other athletes they can still compete at the highest level with a metal hip.
Murray, 33, is making his latest comeback after having the hip resurfacing operation in January 2019.
He beat world number seven Alexander Zverev in the Western and Southern Open, before losing to Milos Raonic.
"Hopefully I have inspired some people who have got these issues and might have the operation," said the Scot.
"To try and show that you can keep going."
Murray is the first player to return to singles after the operation, which sees the femur head capped with metal and put into an artificial socket.
