Abstract:

Objective To investigate the feasibility and effect of  3D-printed navigational templates of tibial tunnel on the anterior cruciate ligament reconstruction. Methods 56 patients of anterior cruciate ligament reconstruction from January 2015 to May 2016 in the orthopaedics department of the Affiliated Hospital of Putian University were selected and randomized into two groups: the control group and the 3D-printed group. The surgical duration and the number of intraoperative tibial tunnel location were recorded and analyzed. The IKDC knee function score, the Lysholm score on the postoperative 6th and 9th months, and the range of motion(ROM) of knee 9 months after operation were examined. The data were analyzed by chi-square test and two-sample t-tests. Results Fifty-two patients were included in the analysis(27 case in control group and 25 cases in the 3D-printed group). There were significant differences in the surgical duration and the number of intraoperative tibial tunnel location(t=4.186,P<0.05;t=3.069,P<0.05). The IKDC knee function score ,the Lysholm score on the postoperative 6th  and 9th months, and ROM of knee 9 months after operation showed no significant difference between the two groups(P>0.05). Conclusion It was a viable alternative to use the 3D-printed navigational template of tibial tunnel for anterior cruciate ligament reconstruction.
