Abstract：Objective: To investigate the clinical outcome of three-dimensional printing technique for the treatment of femoral intercondylar fractures. Methods: Forty eight patients with femoral intercondylar fractures between January 2015 and September 2015 were randomly divided into treatment group and control group. Mimics software was used to reconstruct fracture model and reduction in treatment group, and preoperative plan was designed based on 3D printing model. Control group’s patients underwent traditional treatment. The surgery duration, blood loss, fluoroscopy time and HSS score were collected. Results: The surgery duration in treatment group (61.25±14.28) min was shorter than that in the control group (79.14±18.43) min, blood loss in treatment group (81.74±23.50) mL was less than that in the control group (106.80±22.75) mL while fluoroscopy time also showed better performance (2.10±0.50 vs. 4.10±0.70), and there was significant difference between two groups (P<0.05). After one-year follow up, the knee function in treatment group was better than that in the control group (P<0.05). Conclusion: Three-dimensional printing technique for the treatment of femoral intercondylar fractures can save surgery duration, reduce blood loss to certain extent, and obtaine better clinical outcome compared to traditional treatment.
