VR Simulation and Basic Skills in THA

This prospective randomised clinical trial aims to test if virtual reality (VR) simulation helps acquire basic surgical skills in total hip arthroplasty (THA) by medical students. The main question\[s\] it aims to answer are: 1. Can VR simulation develop the medical students' basic surgical skills and medical knowledge in THA? 2. Will VR simulation become a part of orthopaedic surgical education? Participants will be randomised into two groups (VR and control). 1. They will be asked to watch a very detailed video explaining basic rules and skills in implanting the acetabular cup and femoral stem in THA 2. The VR group will perform at least three VR THA sessions concerning cup (inclination) and stem (version) implantation 3. Then all participants will be asked to implant a cup and a stem in a predefined inclination and version, respectively, in sawbones 4. The mean difference between the predefined and the actual implanted cup inclination and version of the stem will be compared between groups
