中文摘要:
      目的:探讨3D打印技术对关节镜前交叉韧带重建手术的辅助价值。方法:对2017年12月-2018年5月收治的15例因运动损伤导致前交叉韧带断裂且需进行韧带重建的患者,术前进行膝关节CT扫描,Mimcs图像处理,通过3D打印膝关节模型,进行模型上股骨骨隧道定位,并进行预手术,测量隧道长度,术前及术后6个月进行膝关节Lysholm 评分以评估膝关节功能。结果:通过3D打印模型预手术,均较准确地定位了前交叉韧带股骨止点,预手术测量股骨骨隧道平均长度为(43.2±2.13) mm,术中测量(43.7±1.75) mm,术后再次CT测量骨隧道长度为(42.4±3.25) mm,差异无显著性意义(P>0.05),术前Lysholm评分(46.2±5.73) 分,术后Lysholm 评分(88.4±6.25) 分,差异有显著性意义(P<0.05)。结论:3D打印模型预手术可以辅助关节镜术中较快速、准确地定位前交叉韧带股骨止点,模型与实体骨隧道契合度高,术后疗效优良。
英文摘要:
      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.
