Summary
This research study is focused upon assessing and optimising surgeon's performance during, and patient outcomes following, primary total hip replacement (THR) surgery. The primary research question is to determine if additional simulation training can improve the intra-operative performance of surgical trainees (Residents) during a THR, or the outcome of patients after their THR. The investigators will aim to define an 'expert' standard in performing a primary elective THR, which may be used as a benchmark when assessing surgical trainee performance; and also determine if operative surgeon performance metrics during a THR are correlated with surgical experience, or patient outcomes.
Eligibility Criteria
Inclusion Criteria
- Adult patients diagnosed with primary hip osteoarthritis who have been listed for elective primary Total Hip Replacement within the United Kingdoms National Health Service.
- Total Hip Replacement performed by a surgeon participant as lead surgeon.
Exclusion Criteria
- Patients with complex hip pathology (e.g. previous trauma, hip dysplasia, infection).
- Patients who have had previous surgery on their affected hip.
