BACKGROUND: Virtual knee arthroscopy system has achieved some preliminary research results at home and abroad, but it is still unable to be popularized and applied widely because of the high cost. Therefore, we designed a set of simulation endoscopic equipment, which allows the surgeons to promote surgery skills during virtual surgery. OBJECTIVE: To evaluate the training effect of virtual knee arthroscopy system on surgical skills of the beginning students. METHODS: Twenty-four interns and orthopedists (16 interns with no arthroscopy operating experience; eight experts with arthroscopy operating experience) were selected from five different universities and different hospitals, and 16 interns were randomly divided into training group and control group, eight interns in each group. After system training, the training group was compared with the control group and expert group in the virtual knee arthroscopy system operation and clinical surgery operation, and the results were statistically processed. RESULTS AND CONCLUSION: In the virtual endoscope system operation, there was significant difference in the scores between the control and training groups (P0.001), and also between the control and expert groups (P0.001); however, there was no significant difference in the scores between the training and expert groups (P=0.115). In the clinical knee arthroscopy operation, there were significant differences between the training and control groups (P 0.001), between the control and expert groups (P0.001), and between the training and expert groups (P=0.03). Virtual knee arthroscopy system can serve as beneficial surgery skill training for beginning students and the improvement of virtual operation technique may be related to clinical skills.
