Face and Content Validation of the Sim-K Haptic-Feedback Enhanced Total Knee Replacement Virtual Reality Simulator.
Purpose: Virtual reality simulators for open orthopaedic procedures, such as total knee replacement (TKR), are uncommon compared to arthroscopic or fluoroscopic procedures. The Ossim Sim-K is to our knowledge the first virtual reality TKR simulator with haptic feedback, and we sought to investigate the face and content validity of the first iteration of this device.
Primary Objectives: To assess the content and face validity of this prototype TKR surgery simulator. Face and content validity are two important concepts for scientifically evaluating the simulator. Face validity refers to the realism of the experience whilst content validity is a judgement of the teaching ability of the simulator.
Results: The Sim-K was well received, particularly by inexperienced surgeons with respect to both face and content validity. The Sim-K represents a promising start in the production of a TKR simulator with haptic feedback. With further development this system has the potential to be valuable in the training of orthopaedic surgeons.
