Emergency and high risk orthopaedic services will no longer be available at an East Sussex hospital.
East Sussex Healthcare has transferred the services from Eastbourne District General Hospital to the Conquest Hospital in Hastings.
The move is part of a reorganisation that the trust has said will improve services for patients.
During the public consultation process, campaigners said services should be available in both hospitals.
'Needed in a hurry'
Dr Andy Slater, medical director at the trust, said: "By having all emergency and high risk orthopaedics based on one site, we now have more surgeons available to carry out planned procedures and an on-call surgeon to deal with any patients needing emergency care.
"This means we will be able to reduce the number of planned operations that we have to cancel and treat people more quickly, which in turn will improve their recovery."
As part of the restructuring, East Sussex Healthcare NHS Trust said it wanted to centralise stroke services at Eastbourne District General Hospital.
Previously, Liz Walke, who chairs Eastbourne campaign group Save the DGH, said: "These are services that are needed in a hurry and they should be provided at both hospitals."
The trust said most planned operations and outpatient clinics would continue to operate at both hospitals, which also have their own accident and emergency departments.
