• Research summary

  This study aims to explore surgeon specific factors during preoperative planning that contribute to the quality of Total Hip Replacement (THR) surgery as measured via postoperative X-ray imaging. Patient reported outcome measures will also be recorded.

  RATIONALE:
  Over 87, 851 primary total hip replacements (THRs) were carried out in the UK in 2014 (National Joint Registry, 2015). The outcome of total hip replacement (THR surgery varies in quality, which in part depends upon the operating surgeon. Just over 5% of THRs done in the UK (recorded in the National Joint Registry) underwent revision due to component malalignment (National Joint Registry, 2014. Research has not yet identified the reasons for outcome variability between surgeons. However, it is thought that multiple factors, both separately, and in combination will determine the outcome of THR surgery, as in other surgical specialties.

  X-ray imaging is an objective measure of outcome quality and could be used to identify and measure differences in surgical outcomes (such as implant positioning and orientation). For this reason, x-ray quality will comprise the key quality metric for THR variation between surgeons.

  IV. STUDY OBJECTIVES
  The specific study objectives are:
  1. To identify objective and measurable indices on postoperative x-ray of THR as outcome metrics of surgical quality.
  2. To map and compare between surgeons' preoperative planning practices for THR surgery.
  3. To link differences in surgical outcomes, as measured through x-ray imaging, to possible differences in preoperative planning practices between surgeons.
