Hip replacement is a common procedure but patients vary in how well their hip works after surgery. The type of hip implant used may affect how successful the surgery is, but there is no clear evidence on which is the best type of implant. We wish to undertake a trial of two types of implant. This application is for a feasibility study to see if the full trial is possible. Sixty patients from a two hospitals will receive either a ‘cemented’ or a ‘hybrid’ hip replacement. Patients’ hip function will be assessed at 6 weeks and 6 months later using standard questionnaires. Our main outcome is the rate of recruitment. We want to know how many patients will agree to take part, how long recruitment will take, and whether patients will complete the follow-up assessments after surgery. We will also learn how many patients will be needed for the full trial. In interviews, we will ask patients about their experiences of the trial and their reasons for taking part; we will also ask people who declined about their thoughts. We will ask surgeons about their willingness to take part in a trial and about any barriers there might be to changing their surgery practice following the full trial results. This topic of research has been discussed with patients at our patient and public involvement (PPI) group and we have received positive feedback that it is important and that patients would be happy to take part. The PPI group will be involved throughout the study, giving guidance with patient information sheets and letters. We will present the findings in scientific meetings and peer reviewed journals and share with professional bodies. Our PPI group will advise on sharing the research.
