• Research summary

  BACKGROUND
  Total hip replacement (THR) is a successful operation for the majority of people. However, more than 10% of patients remain with pain in the operated hip one year after their operation and more than 6% are dissatisfied with their surgery.

  The most common method to complete a hip replacement uses the posterior approach (PA), which involves cutting and repairing three tendons. Modified versions of the PA have been developed where only one or two tendons are cut. However, cutting fewer tendons can limit the visibility and access to the hip joint, and can make positioning the THR more challenging. Robotic-assisted surgery allows accurate positioning of the THR. This may compensate for the reduced visibility of the hip joint when fewer tendons are cut.

  PROJECT AIM
  We will compare the outcome of THR completed using a standard PA where three tendons are cut, with modified versions where either two tendons, or only one tendon is cut. All surgery will use robotic assistance, so the only difference between groups will be the number of tendons that are cut. This will allow us to assess if cutting fewer tendons is beneficial to patients.

  PATIENT AND PUBLIC INVOLVEMENT AND ENGAGEMENT (PPIE)
  A PPIE workshop was held, pilot data was collected (n=17) to inform the number of patients needed for this study, and activity data (n-13) was used to refine activity monitoring methods. Further discussions led the PPIE group to recommend specific patient reported outcome measures and activity monitoring parameters that will be used in this study.

  PROMOTING RESULTS
  The study results will be shared with orthopaedic community through academic journals and conferences, and the Exeter Hip Unit training and teaching programmes. Results will be shared with the wider public through the PPI group, the Hip Unit website and social media accounts, and public engagement activities.
