Assessing impingement risk and patient outcomes after total hip arthroplasty with optimized acetabular cup placement

Total hip replacement usually provides good outcomes for patients. Sometimes, if one part of the artificial hip is placed incorrectly, it can cause the hip to dislocate and require a second surgery to fix the implant. New computer software has been developed by our partner to guide the surgeon during the operation to place the artificial hip in the best spot for each patient. We will use x-rays taken with the patient in different leg positions after surgery to see if using this software will lower the risk of the hip dislocating, compared to patients who had hip replacement without the software. CT imaging will be conducted to gain a better understanding of possible bone and muscle quality factors influencing dislocation. Patients will also complete a questionnaire asking about their outcomes. If patients who had hip replacement with the software have better outcomes and less dislocation risk, this will provide evidence the partner can use to help support the use of the software more routinely in our healthcare system.
