Mixed Reality vs. Traditional Arthroscopic Simulation
10. juni 2026 oppdatert av: Javier Pereira, Universidade da Coruña
Comparative Effectiveness of Mixed Reality Versus Traditional Simulation in Arthroscopic Surgical Training: A Parallel-Group Randomized Trial
This randomized controlled trial evaluates and compares the educational effectiveness of two arthroscopic training platforms: a traditional physical bench-model simulator and an immersive Mixed Reality (MR) simulator.
Medical students and residents undergo a baseline assessment on a physical knee simulator and are then randomized into either the Traditional Simulator Group (TSG) or the Mixed Reality Simulator Group (MRSG).
Participants complete a three-session training protocol focusing on basic psychomotor skills.
Trainees are then evaluated on an anatomical knee task to measure true clinical skill transfer.
Performance is video-recorded and scored by independent, blinded physicians using the validated Arthroscopic Surgical Skill Evaluation Tool (ASSET).

Detaljert beskrivelse
This parallel-group randomized controlled trial aims to evaluate the educational efficacy of Mixed Reality in surgical education. Medical students and residents undergo a baseline assessment on a physical anatomical knee simulator to establish initial skill levels. Following this, participants are randomized into either the Traditional Simulator Group (TSG) or the Mixed Reality Simulator Group (MRSG).
The intervention consists of a three-session training protocol focusing on basic psychomotor skills (specifically horizontal and spatial triangulation) isolated from anatomical clutter. To evaluate true clinical skill transfer, trainees are then tested on an identical anatomical knee task. All performance sessions are video-recorded and subsequently scored by independent, blinded physicians using the validated Arthroscopic Surgical Skill Evaluation Tool (ASSET) to ensure objective outcome measurement.

Aktiv komparator: Traditional Simulator Group (TSG)
Participants train using a traditional physical bench-model simulator.
The system features an enclosed chamber occluded from direct line-of-sight, forcing trainees to rely exclusively on an external video monitor for visual guidance.
The training consists of three individual sessions (maximum 10 minutes each) performing horizontal coordination and spatial triangulation tasks using physical tools.

Eksperimentell: Mixed Reality Simulator Group (MRSG)
Participants train using an immersive Mixed Reality (MR) simulator.
The system uses MR glasses to view holographic images inside the enclosure and provides instructional visual guidance via a virtual monitor, replacing the traditional external video monitor.
The training consists of three individual sessions (maximum 10 minutes each) performing horizontal coordination and spatial triangulation tasks using physical tools.

Perceived Workload Assessed by the SURG-TLX Scale
Tidsramme: Time Frame: Baseline (before intervention; completed immediately after Phase 1 on the same day) and immediately after completion of the intervention (completed immediately after Phase 3 on the same day)
|
Perceived cognitive and physical workload during the evaluation tasks is measured using an adapted Surgery Task Load Index (SURG-TLX).
The questionnaire evaluates six dimensions: mental demands, physical demands, temporal demands, task complexity, situational stress, and distractions using a 5-point Likert scale.
The total score ranges from 6 to 30, with higher scores indicating a higher perceived workload.

Perceived workload during the Phase 2 tasks is measured using an adapted NASA Task Load Index (NASA-TLX).
The questionnaire assesses six dimensions: mental demand, physical demand, temporal demand, performance, effort, and frustration.
Each item is rated on a 5-point Likert scale.
The total score ranges from 6 to 30, with higher scores indicating greater perceived workload.
