Abstract Objective: To investigate the clinical effect of 3D printing combined with traditional steel plate internal fixation on complex tibial plateau fractures (CTPF). Method: A total of 60 CTPF patients admitted to Jingdezhen Fifth People's Hospital from February 2022 to January 2023 were selected, and divided into the study group (n=30) and the control group (n=30) by random number table method. The control group was treated with traditional steel plate internal fixation, the study group was treated with 3D printing combined with traditional steel plate internal fixation. The clinical indicators, knee joint range of motion (ROM), knee joint function, motor function, and complications of the two groups were compared. Result: The number intraoperative fluoroscopy times and the amount of intraoperative bleeding in the study group were less than those in the control group, and the time of fracture reduction, surgery, and hospitalization were shorter than those in the control group, the differences were statistically significant (P<0.05). Three months after surgery, the ROM of flexion and extension in both groups were increased, the study group were larger than those in the control group, the differences were statistically significant (P<0.05). Three months after surgery, the knee joint scores of hospital for special surgery (HSS) of New York and Fugl-Meyer motor function assessment scale for lower extremity (FMA-LE) scores in both groups were improved, and the study group were higher than those in the control group, the differences were statistically significant (P<0.05). The incidence of complications in the study group (6.67%) was lower than that in the control group (30.00%), the difference was statistically significant (P<0.05). Conclusion: 3D printing combined with traditional steel plate internal fixation for the treatment of CTPF can reduce intraoperative bleeding and fluoroscopy times, shorten fracture reduction and surgical time, promote postoperative recovery, enhance knee joint mobility, improve knee joint function and motor function, and reduce the incidence of complications.
