Abstract

Background: Preservation of hamstring tendon insertion at the time of anterior cruciate ligament (ACL) reconstruction is a well-known technique; however, its effect on graft integration is not well studied. The present study was conducted to study the graft integration inside the tibial and femoral tunnels, respectively, after ACL reconstruction using hamstring tendon graft with preserved insertion.

Methods: Twenty-five professional athletes who underwent ACL reconstruction using hamstring tendon graft with preserved tibia insertion were enrolled in the study. Functional outcomes were checked at final follow-up using Lysholm score and Tegner activity scale. Magnetic resonance imaging (MRI) was done at 8 months and 14 months follow-up to study the graft tunnel integration of the ACL graft at both tibial and femoral tunnels.

Results: The mean Fibrous interzone (FI) score (tibial tunnel) decreased from 2.61 (1-5) at 8 months to 2.04 (1-4) at 14 months follow-up (p = 0.02). The mean FI score (femoral side) decreased from 3.04 (2-5) at 8 months to 2.57 (2-4) at 14 months (p = 0.02).

Conclusions: Graft integration occurs early in the tibial tunnel as compared with the femur tunnel with preserved insertion hamstring tendon autograft.

与股骨隧道相比，使用保留插入腘绳肌腱移植物进行前交叉韧带重建后，胫骨隧道内的移植物隧道整合发生得更早。

背景：在前交叉韧带（ACL）重建时保留腘绳肌腱插入部是一项众所周知的技术，但其对移植物整合的影响尚未得到很好的研究。本研究旨在研究使用保留插入部位的腘绳肌腱移植物进行前交叉韧带重建后，移植物分别在胫骨和股骨隧道内的整合情况：方法：25 名专业运动员接受了前交叉韧带重建术，使用保留胫骨插入的腘绳肌腱移植物。最后随访时使用 Lysholm 评分和 Tegner 活动量表检查功能结果。分别在随访 8 个月和 14 个月时进行核磁共振成像（MRI），以研究前交叉韧带移植物在胫骨和股骨隧道内的融合情况：纤维区（FI）平均得分（胫骨隧道）从 8 个月时的 2.61（1-5）降至 14 个月随访时的 2.04（1-4）（P = 0.02）。平均FI评分（股骨侧）从8个月时的3.04（2-5）降至14个月时的2.57（2-4）（P = 0.02）：结论：与保留插入腘绳肌腱自体移植物的股骨隧道相比，胫骨隧道的移植物整合发生得更早。试验注册号：CTRI/2019/07/020320 [注册日期：2019年7月22日]；http://www.ctri.nic.in/Clinicaltrials/pdf_generate.php?trialid=33884&EncHid=&modid=&compid=%27,%2733884det%27。
