| Scientific title | The Warwick Arthroplasty Trial: a randomised controlled trial of total hip arthroplasty versus resurfacing hip arthroplasty in the treatment of young patients with arthritis of the hip joint |
| Study acronym | WAT |
| Study objectives | There is no difference in hip function in patients with severe arthritis of the hip joint who have undergone a total hip arthroplasty or a resurfacing arthroplasty at one year post-operation. |
| Ethics approval(s) | Approval received from the Coventry Research Ethics Committee on the 9th May 2007 (ref: 07/Q2802/26). |
| Health condition(s) or problem(s) studied | Osteoarthritis of the hip joint |
| Intervention | 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.
