The indications for OTT ACLR are varied and include scenarios such as (1) revision surgery when femoral bone loss isometric, preventing further femoral tunnel techniques for graft positioning or fixation; (2) to address an intraoperative posterior cortical wall “blowout” that obstructs graft fixation; (3) when alternative methods are ...

Anterior cruciate ligament (ACL) injuries are the most common knee joint injuries related to sports activities in clinical practice. For treating ACL injuries, anatomical reconstruction surgery is often the preferred method. The over- the- top (OTT) technique is a surgical approach that eliminates the need for creating a femoral tunnel.

2022年12月14日 · Purpose: To compare anterior laxity and in situ forces of the ACL graft between conventional OTT and supra-OTT ACLR in a cadaveric model. Study design: Controlled laboratory study. Methods: A total of 11 fresh-frozen cadaveric knee specimens underwent 4 robotic testing conditions: ACL intact, ACL resected, conventional OTT, and supra-OTT.

Purpose: To investigate the objective outcomes following anterior cruciate ligament reconstruction (ACLR) with the over-the-top (OTT) technique. Methods: Thirty-five ACL-deficient patients with mean follow-up of 2.2 years were retrospectively reviewed.

2019年9月23日 · Anterior cruciate ligament reconstruction (ACLR) with the over-the-top (OTT) technique, in which the graft is passed over the superomedial border of the lateral femoral condyle and fixed on the distal lateral femoral shaft, was originally used for primary ACLR [12, 13].

2024年10月27日 · 前十字韧带重建（aclr）是骨科运动医学中最常用的手术之一，旨在恢复膝关节稳定性，促进恢复活动，并防止软骨和半月板二次损伤。 对膝关节解剖学和生物力学的了解的提高导致了手术技术的进步，现代“解剖”技术已在大多数患者中显示出良好的结果。

2024年3月22日 · This technical note describes the surgical technique for double-bundle OTT revision ACLR with associated LET by hybrid hamstring tendon autograft-allograft. This technique provides a valid treatment for revision ACLR, especially in patients with malpositioned and widened tunnels which were close to the femoral position of posterolateral bundle.

The over-the-top (OTT) technique is a surgical approach that eliminates the need for creating a femoral tunnel. According to the existing literature, the OTT technique offers distinct advantages, particularly for skeletally immature individuals and in revision cases.

背景 多次翻修前交叉韧带重建 (ACLR) 存在一些技术挑战，通常是由于残留硬件、隧道加宽、错位或分期手术造成的。 目的 比较因 ACLR 翻修失败而接受手术的患者采用 Over-the-top (OTT) 和运输钻孔 (TD) 技术的失败率和并发症率。 研究设计队列研究；证据级别，3。 方法对使用 OTT 或 TD 技术进行至少 2 次 ACLR 修订的患者的医疗记录进行回顾性审查。 收集有关患者人口统计、移植特征、翻修次数、伴随手术、并发症和失败的数据。 连续变量和分类变量的组间比较分别 …

2023年10月11日 · This technical note describes the surgical technique for double-bundle OTT revision ACLR with associated LET by hybrid hamstring tendon autograft-allograft. This technique provides a valid treatment for revision ACLR, especially in patients with malpositioned and widened tunnels which were close to the femoral position of posterolateral bundle.
