The study presents an arthroscopic transosseous suture bridge technique for repairing avulsion fractures of the tibial insertion of the anterior cruciate ligament (ACL), specifically tailored for adolescent patients. The technique utilizes two mini tunnels, integrating the principles of transosseous tunneling and suture bridging to ensure stable fixation while minimizing the impact on the bone bed. Over a seven-year period, 39 patients with Meyers-Mckeever types II, III, and IV tibial avulsion fractures underwent this procedure. The surgery had an average duration of 52.7 min and resulted in decreased swelling and pain within two months postoperatively. All patients achieved full knee extension and over 120° of flexion. X-rays confirmed complete fracture healing within six to 12 months, and negative anterior drawer test and Lachman test indicated stable fixation. Significant improvements were seen in Lysholm and IKDC scores. This technique offers several advantages: it is effective, stable, and particularly suitable for adolescents due to the reduced impact on the bone bed and successful avoidance of epiphyseal plate injury.
本研究提出了一种关节镜下经骨缝合桥技术，用于修复前交叉韧带（ACL）胫骨止点撕脱骨折，特别适用于青少年患者。该技术采用两个微型隧道，结合经骨隧道和缝合桥接的原理，以确保稳定固定，同时将对骨床的影响降至最低。在七年期间，39 名 Meyers-Mckeever Ⅱ型、Ⅲ型和Ⅳ型胫骨撕脱骨折患者接受了该手术。手术平均持续 52.7 分钟，术后两个月肿胀和疼痛减轻。所有患者均实现完全膝关节伸展和超过 120°的屈曲。X 射线证实骨折在 6 至 12 个月内完全愈合，且前抽屉试验和 Lachman 试验均为阴性，表明固定稳定。Lysholm 和 IKDC 评分均显著改善。该技术具有以下优点：有效、稳定，尤其适用于青少年，因为对骨床的影响较小，成功避免了骺板损伤。
