Abstract：Objective To evaluate the efficacy of application of 3D printing personalized femoral lateral positioning auxiliary method in ACL reconstruction surgery. Methods From January 2015 to August 2016,26 cases were performed 3D printing personalized femoral lateral positioning auxiliary method(3D modeling,ACL femoral printing area location) preoperatively, and were divided into 3D group. All 26 cases whose IKDC knee functional scores were more than 85 points and perrformed conventional method were divided into control group. Postoperative X-ray evaluation method was performed for evaluation be-tween the two groups. Results Surgery in all cases was successful and no complications occurred. Preoperative modeling in 3D group was smooth. Localization lateral femoral tunnel,lateral femoral tunnel length was(42. 6 ± 42. 6) mm,and lateral femoral tunnel length was about ( 39. 2 ± 39. 2 ) mm. There was no statistical significance between the two groups ( P >0. 05). NL/ML,AL/BL,alpha and beta angle differences had no statistical significance(P>0. 05)between the two gorups. Conclusion Application of 3D printing personalized femoral lateral positioning auxiliary method in ACL reconstruction sur-gery will be good to pinpoint femoral anatomic point,control the needle direction,and will be good for tendon bone healing, reducing the probability of “ringing” rear cortex.
