Interventions
|
1. Patients in the Total Hip Arthroplasty group will have the head of their femur removed and replaced with a prosthetic component fixed inside the femoral shaft
2. Patients in the Hip Resurfacing Arthroplasty group will have a resurfacing ‘cap’ placed upon their existing femoral head
Both groups will have a new acetabular (socket) component. The details of both operative procedures will be left to the discretion of the surgeon to increase generalisabilty of the result. All patients will receive standardised rehabilitation after the operation. As part of the research patients will be followed-up for one year post-operation.
