Abstract

Abstract: Objective To explore the effect of a 3D surgical training system in the teaching of patella fracture surgeries to orthopedic residents. Methods A total of 24 participants from the standardized residency training program at Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, from September 2022 to September 2023, were selected and assigned into two groups using a random number table method, with 12 in the experimental group receiving the course using 3D surgical training system and 12 in the control group receiving traditional instruction. The teaching effectiveness was evaluated using knowledge examination, skills assessment, and satisfaction surveys. T-tests and chi-square tests were used for data analysis. Results In knowledge examination, total scores for the experimental group were (81.42±4.68) and (75.42±6.52) for the control group, with a statistically significant difference (t=2.59,P=0.017). In skills assessment, there were no significant differences between the experimental group and the control group interms of the duration of fracture reduction was (20.25±5.26) minutes for experimental group and (23.67±4.83) minutes for control group , the number of fluoroscopies use was (2.75±1.06) times for experimental group and (3.00±1.28) times for control group, and intraoperative blood loss was (97.92±10.10) ml for experimental group and (100.40±7.82) ml for control group (P>0.05). The time taken for the tension band was (32.92±6.20) minutes for the experimental group and (38.42±3.63) minutes for the control group, a statistically significant difference (t=2.65, P=0.015). The overall surgical duration was (86.17±11.42) minutes for the experimental group and (100.20±12.22) minutes for the control group, with a statistically significant difference (t=2.90, P=0.008).After completing all assessment components, the control group participants joined the experimental group′s course and participated in a satisfaction survey.satisfaction survey showed that 22(91.7%) were willing to recommend the teaching method, and 20(83.4%) found the teaching method impressive. Conclusions The application of the 3D surgical training system helped improve the theoretical knowledge acquisition of orthopedic residents in patella fracture surgery training and reduced the overall surgical time, and achieved high levels of teaching satisfaction and effectiveness.
