Arthroscopic Basic Task Performance in Shoulder Simulator Model Correlates with Similar Task Performance in Cadavers
Background:Attainment of the technical skill necessary to safely perform arthroscopic procedures requires the instruction of orthopaedic surgery residents in basic arthroscopic skills. Although previous studies involving shoulder arthroscopy simulators have demonstrated a correlation between task performance and the level of prior arthroscopic experience, data demonstrating the correlation of simulator performance with arthroscopic skill in a surgical setting are scarce. Our goal was to evaluate the correlation between timed task performance in an arthroscopic shoulder simulator and timed task performance in a cadaveric shoulder arthroscopy model. Methods:Subjects were recruited from among residents and attending surgeons in an orthopaedic surgery residency program. Each subject was tested on an arthroscopic shoulder simulator and objectively scored on the basis of the time taken to complete a standardized object selection program. After an interval of at least two weeks, each subject was then tested on a cadaveric shoulder arthroscopy model designed to replicate the shoulder arthroscopy simulator testing protocol, and the time to completion was again recorded. Both testing protocols involved the simple task of placing a probe on a series of assigned locations in the glenohumeral joint. Spearman rank correlation analysis was performed, and regression analysis was used to determine the predictive ability of the simulator score. Results:The performance time on the simulation program was strongly correlated with the performance time on the cadaveric model (r=0.736, p<0.001). The time required to complete the simulator task was a significant predictor of the time required to complete the cadaveric task (t=4.48, p<0.001). Conclusions:These results demonstrated a strong correlation between performance of basic arthroscopic tasks in a simulator model and performance of the same tasks in a cadaveric model.
