Abstract: Objective To evaluate the effect of modularized simulation-based training mode in arthroscopic surgery. Methods Totally 111 refresher physicians who participated in the training of shoulder arthroscopic surgery simulation from April 2018 to October 2019 in Beijing Johnson & Johnson Training Center were recruited. All the participants conducted on-site training record and questionnaire survey. Non-parametric Mann-Whitney U test and T test were used to analyze the obtained data. Results On completion of the training, participants showed significant improvement in the time of grasping and transferring [(202.92±27.86) seconds vs. (123.44±18.93) seconds], for the time of suturing and knotting, the training also witnessed significant decrease [(333.77±24.36) seconds vs. (183.92±14.19) seconds] (all P<0.05). After the training, the times of grasping and transferring shortened [43.5(9.0,60.5)] seconds in tertiary hospital group and [40.0(19.5,147.0)] seconds in non-tertiary hospital group, while the time of suturing and knotting shortened [85.0(60.0,180.0)] seconds in tertiary hospital group and [120.0(60.0,260.0)] seconds in non-tertiary hospital group. There was no significant difference between the refresher physicians come from the tertiary hospitals and non-tertiary hospitals groups regarding the shortened time (all P>0.05). The orthopedics group improve [60.0(23.0,90.0)] seconds in the time of grasping and transferring and the sports medicine group improve [20.0(6.0,60.0)] seconds (P<0.05). For the time of suturing and knotting, [80.0(52.0,172.3)] seconds and [90.0(60.0,275.0)] seconds were improved respectively. The difference was not statistically significant (P>0.05). The refresher physicians satisfaction of the simulation training is 100.0% (111/111). Conclusions The basic surgical skills of refresher physicians from both orthopedics and sports medicine after the training of modular arthroscopic surgery simulation are significantly improved. The method is suitable for refresher physicians from hospitals of different levels and for both orthopedics and sports medicine.
