Abstract：Objective To compare the clinical efficacy of traditional surgery and surgery assisted by 3D printing technology in the treatment of complex tibial plateau fractures.Methods A retrospective analysis was per-formed on 51 cases of complex tibial plateau fractures at Department of Orthopedics of Wuhan General Hospital of PLA from Dec.2013 to Sep.2016.According to the Schazker classification,33 cases were typeⅤand 18 cases wereⅥ.These patients were divided into two groups as 3D printing assisted operation group and traditional operation group,according to whether 3D printing technology was applied.The 3D printing assisted operation group included 12 males and 7 females(aging from 21 to 65 years,mean age 44.7),and the traditional operation group included 19 males and 13 females(aging from 19 to 62 years,mean age 47.1).Operation time,blood loss,and times of intra-op-erative fluoroscopy were recorded.Through the follow-up,the recovery of patients was observed by Rasmussen score and the HSS knee function score.Results All the patients were followed up for 11 to 22 months.The average op-eration time,average amount of blood loss,and the times of intra-operative fluoroscopy for 3D model group was (97.7 ±13.7)minutes,(207.4 ±41.7)mL,(4.6 ±1.5)times,and for traditional surgery group was(110.5 ± 17.7)minutes,(291.1 ±5.2)mL,(6.4 ±1.7)times,respectively.There was statistically significant difference between the traditional surgery group and 3D model group(P<0.05),but the difference in 6-month post-operation Rasmussen score and HSS score had no statistical significance.Conclusion Compared with traditional surgery,3D printing technology assisted operation for complex tibial plateau fractures can significantly reduce operative time,re-duce operative bleeding and fluoroscopy times,but fail to improve knee joint function at 6 months after operation.
