3D printing femoral tunnel precise positioning method combined with LARS artificial ligament grafts in the anterior cruciate ligament reconstruction surgery

目的评价应用3D打印股骨隧道定位器精确定位结合LARS人工韧带移植在前交叉韧带(ALC)重建手术的临床效果。方法选取2013年10月至2016年8月接受关节镜下应用LARS人工韧带重建ACL的患者42例,其中,应用3D打印股骨定位器的21例患者为3D组,术中应用传统定位器进行股骨隧道定位21例患者为对照组。评估两组平均手术时间、术后膝关节X线影像、术后并发症及膝关节功能评分。结果与对照组比较,3D组平均手术时间短、术后并发症少。两组间膝关节功能评分比较,术后1周有明显差异(P<0.05),术后3月无统计学差异(P>0.05)。结论应用3D打印个性化股骨隧道定位法定位人工韧带股骨隧道位置,可精准定位术前评估的最佳位点,明显缩短手术时间,减少术后膝关节并发症的发生,达到快速康复的目的。

Objective To explore the efficacy of 3D printing femoral tunnel precise positioning method combined with LARS artificial ligament grafts in the anterior cruciate ligament（ ACL） reconstruction surgery. Methods A retrospective study was performed on42 patients underwent arthroscopic ACL reconstruction combined with LARS artificial ligament from October 2013 to August 2016. Among the patients,21 cases were performed 3D printing femoral tunnel located method preoperatively as 3D group,26 cases with traditional femoral locater as control group. The average operation time,postoperative knee X-ray optical imaging,postoperative complications and knee function score between the two groups were assessed. Results Compared with the control group,there was shorter average operation time and less postoperative complications in 3D group. Lysholm knee function score comparison between the two groups,there was significant difference（ P〈0. 05） in 1 week postoperatively,no statistical difference in 3 months postoperatively（ P〈0. 05）.Conclusion 3D printing femoral locater auxiliary method in ACL reconstruction surgery can precisely location the best femoral site,significantly shorten the operation time,reduce the postoperative complications and achieve the goal of fast rehabilitation.
