Methods: A total of 50 postgraduate students undergoing orthopedic clinical rotation training in our hospital were enrolled and randomly divided into an integrated teaching group and a conventional teaching group via the random number table method, with 25 students in each group. The integrated teaching group adopted the PBL teaching method embedded with digital teaching resources, while the control group received conventional single PBL teaching. Before and after the teaching intervention, unified theoretical knowledge examinations, simulated model operation skill assessments, and teaching satisfaction questionnaires were conducted to evaluate the teaching efficacy of the two groups. Results: After the teaching intervention, the scores of theoretical knowledge, practical operation skills, and teaching satisfaction in both groups were significantly higher than those before the intervention (all P < 0.05). Moreover, the integrated teaching group presented remarkably better improvement in all evaluation indicators than the control group, and the between-group differences were statistically significant (all P < 0.05). Conclusion: The digital-resource-embedded PBL model can effectively optimize the theoretical mastery and clinical operative skills of orthopedic postgraduates in microvascular anastomosis training, improve students’ self-directed learning ability, and achieve better teaching outcomes than traditional PBL. This innovative teaching model is worthy of popularization and application in advanced technical training of orthopedic microsurgery.Digital resource embedding, Problem-based learning, Orthopedic postgraduates, Microvascular anastomosis, Surgical skill training
