自体松质骨间置增强腘绳肌腱前交叉韧带重建中肌腱-骨愈合：一项手术技术
简介
该文介绍一种利用胫骨隧道扩孔时获取的自体松质骨，通过注射器鞘收集并包裹于腘绳肌腱移植物周围，以增强肌腱-骨整合的手术技术。该方法旨在改善移植物-隧道界面的生物学与力学环境，实现压配固定，可能减少骨道扩大，且无需额外取材或生物制剂。
英文摘要
Hamstring tendon autografts remain a popular choice for anterior cruciate ligament reconstruction due to their favorable biomechanical properties and reduced donor-site morbidity; however, delayed tendon-to-bone integration and tunnel widening continue to limit outcomes when compared with bone-patellar tendon-bone grafts. Biological augmentation with autologous bone offers the potential to improve both the biological and mechanical environment at the graft-tunnel interface. We describe a simple, reproducible, and cost-effective surgical technique that utilizes cancellous bone harvested during tibial tunnel reaming to biologically and mechanically augment hamstring tendon anterior cruciate ligament reconstruction. Using a 10-mL syringe sheath, bone reamings are collected, consolidated on the back table, and interposed within the graft and secured with circumferential 0-Vicryl sutures. The graft is then sized, inserted, and fixed with a femoral EndoButton and tibial interference screw. This approach provides a biologically favorable and mechanically stable construct using autologous bone readily obtained during routine anterior cruciate ligament reconstruction. It offers a pragmatic means to promote tendon-bone healing, enhance press-fit fixation, and potentially reduce tunnel widening without additional graft harvest or biologic adjuncts.
