Details of joint replacement surgeries are being added to an orthopaedic register, health officials said.
They said Jersey had joined the National Joint Register, which looks at data on joint replacement surgeries to improve outcomes for patients.
It already has records of 4.5 million operations performed in England, Wales, Northern Ireland, the Isle of Man and Guernsey, with an estimated 250,000 added each year.
Health and Care Jersey said it had joined the register to help “enhance orthopaedic care” for patients at home and benefit from research and innovation.
