| Objective: To evaluate the value of 3D printing in arthroscopic anterior cruciate ligament reconstruction.Methods: In 15 cases from December, 2017 to May 2018 of anterior cruciate ligament rupture caused by injury and ligament reconstruction patients, preoperative knee CT scan, Mimcs image processing are accomplished by 3d printing knee joint model to model the femur bone tunnel positioning, and pre-operate, measure the tunnel length, preoperative and postoperative 6 months for knee joint Lysholm score in the evaluation of knee joint function.Results: Preoperative surgery through 3d printing model are more accurately positioning anterior cruciate ligament femoral check points. The mean length of the femoral bone tunnel measured by preoperative surgery was (43.2±2.13) mm, by intraoperative measurement(43.7±1.75) mm, by postoperative CT measurement again (42.4±3.25) mm, and there was no significant difference (P>0.05). Preoperative Lysholm score was (46.2±5.73) points while postoperative Lysholm score was (88.4±6.25) points, and there were significant differences (P<0.05).Conclusion: 3D printed model preoperative surgery can assist in the rapid and accurate positioning of the anterior cruciate ligament femoral insertion during arthroscopy. The fit between the model and the solid bone tunnel is high, and the postoperative efficacy is excellent. |
