  • Research summary

    Total hip replacement is one of the most commonly performed surgical procedures, with over 87,000 primary hip replacements and 7900 revision hip replacements carried out in the UK each year. Dislocation following total hip replacement is the most common reason for revision within the first year following surgery. Patients are routinely advised to follow hip precautions to restrict hip movement and are provided with equipment to reduce the risk of dislocation in the first few months following surgery.
    The Dual Mobility hip replacement is an alternative design of hip replacement that has increased stability and lower risks of dislocation compared to the standard designs routinely used across the UK. The Dual Mobility hip has been used for more than 35 years in Europe and America and more recently in the UK for patients who are considered at high risk of dislocation. However the indications for the use of Dual Mobility implants are expanding to include more active people requiring hip replacement. Due to the inherent stability of the implant patients who have a Dual Mobility hip replacement are not routinely instructed to follow the precautions and therefore are able to move their hip without restrictions as comfort allows. However there are potential benefits of the Dual Mobility hip replacement other than a reduced dislocation rate, such as improved patient satisfaction, faster return to activity and potential overall cost savings to the NHS.

    We are carrying out a research study to see if patients receiving a Dual Mobility hip replacement have a better outcome following surgery compared with the current standard hip replacement.
    We are recruiting 100 patients to participate in this study. Half will receive the standard hip replacement, and associated precautions to restrict hip movement. The other half will have the Dual Mobility hip replacement and be advised to move their hip as comfort allows with no restrictions.
    We will then compare patient satisfaction, quality of life and return to functional activity to see if one group does better than the other.
