Abstract
Objective To validate the low-cost model for arthroscopy training and analyze the acceptance
and usefulness of the developed simulator in medical teaching and training.
Method Ten medical students, ten third-year orthopedic residents, and ten shoulder surgeons
performed predetermined tasks on a shoulder simulator twice. The parameters used were
time to complete the tasks, number of looks at the hands, GOALS score (Global Operative
Assessment of Laparoscopic Skills) and comparison between groups and within groups.
An adapted Likert scale was applied addressing the individuals' impressions about
the simulator and its applicability.
Results In the intergroup comparison, the shoulder surgeons had better scores and times than
the other groups. When the tasks were repeated, the group of surgeons had a 59% improvement
in time (p < 0.05), as did the group of medical students. In the GOALS score, shoulder
surgeons had consistently better scores than the other groups. And when we evaluated
the evolution from the first to the second test, the group of surgeons and the group
of academics had a statistically significant improvement (p < 0.05). In terms of lookdowns,
there was a decrease in all groups. There was consensus that the simulator is useful
in training.
Conclusion The simulator developed allowed the differentiation between individuals with different
levels of training in arthroscopic surgery. It was accepted by 100% of the participants
as a useful tool in arthroscopic shoulder surgical training.
