3D-printing of bones is novel way in preoperative planning giving the surgeon a real-size fracture to evaluate by hand. There are studies from China showing shorter operation time, intraoperative blood loss, and better functional outcome but there are no studies assessing the impact on the preoperative plan.

To assess the effect of 3D-printed proximal tibia fractures in the preoperative plan. Secondarily, to perform subanalysis of the effect divided on operative experience.

Materials and Methods
Data on bicondylar proximal tibia fractures treated with open reduction and internal fixation including dual plating was retrieved for 2019. We included 10 consultants in traumatology to perform a preoperative plan on the basis of CT- scan two times, thereafter the 3D-print, and divided them in to senior consultants and consultants, all specialized in traumatology. Data was entered in an electronic database. We defined a critical change in the preoperative plan as a change in the operative starting point, arthroscopic use, posterior plate, solitary screws, elevation of joint surface through fenestra, and in auto-/allograft use. Minor change was defined as change in length of plates. The surgeons evaluated their confidence after each preoperative plan. Chi-square test was used for categorical group comparison.

There were 10 3D-printed proximal tibia fractures, median age 59 (range 45-79), 5 were female, and 92% were min. Schatzker type 4. The 3D-print lead to a critical change in 27% of the preoperative plans with no difference between junior or senior surgeons (p=0.11). The amount of changes was median 1 (1-5). There were 34% minor changes with no differences among the surgeon groups (p
Interpretation / Conclusion
3D-print of proximal tibia fractures has a significant effect leading to a critical change in 27% of the preoperative plans with no difference due to the surgeons’ experience.
