Primary outcomePrimary: Surgeon Participant Intra-operative Motion Analysis — 171,967; 172,258; 150,505 Movement counts
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.
