Summary
New visual parameters objectively assess arthroscopic surgical skill, correlating strongly with existing methods. These simple metrics can help evaluate surgical residents
Area of Science:
- Orthopaedic surgery training and assessment
- Surgical skill acquisition and evaluation
Background:
- Reduced working hours impact orthopaedic surgical resident training.
- Concerns exist regarding technical skill acquisition due to decreased clinical exposure.
- Objective surgical skill assessment methods are needed.
Purpose of the Study:
- To determine if novel visual parameters objectively discriminate arthroscopic experience levels.
- To evaluate correlations between new parameters and established skill assessment methods.
Main Methods:
- 27 subjects (novice, resident, expert) performed knee arthroscopy on a simulator.
- Performance assessed using novel parameters: instrument loss, triangulation time, lookdowns.
- Validated methods (global rating scale, motion analysis) were also used.
Main Results:
- All three novel visual parameters showed significant performance differences across experience groups (p < 0.05).
- Novel parameters strongly correlated with validated skill assessment methods (p < 0.0001).
Conclusions:
- Three novel visual parameters demonstrate construct validity for objective arthroscopic performance assessment.
- These parameters are simple, usable in the operating room, and correlate with current validated methods.
