采用精准测量技术的全内前交叉韧带重建
简介
针对全内 ACL 重建中移植物关节内长度（IAL）测量不准可导致移植物“触底”（bottoming out）和胫骨骨道过度消耗的问题，本文描述一种术中个体化测量 IAL、并据此制作合适长度骨道的技术；其测值取决于患者膝关节尺寸和术中骨道位置。摘要未报告病例数、对照或随访结果，仅称该技术可减少移植物-骨道不匹配、提高移植物固定稳定性，从而优化全内 ACL 重建…
英文摘要
The all-inside anterior cruciate ligament reconstruction technique is characterized by closed bone sockets for anterior cruciate ligament graft passage and typically adopts suspensory fixation instead of screw fixation. Inaccurate determination of the intra-articular length (IAL) of the graft is associated with an elevated risk of graft "bottoming out" and excessive length consumption of the tibial sockets. Notably, the IAL is dependent on the patient's knee dimensions and intraoperative tunnel positioning, thus requiring individualized measurement. Herein, we propose an intraoperative method for accurate IAL measurement in all-inside anterior cruciate ligament reconstruction, which enables the creation of bone sockets with appropriate lengths based on individual IAL values. This technique effectively mitigates graft-tunnel mismatch and improves the stability of graft fixation, thereby optimizing the clinical outcomes of the all-inside anterior cruciate ligament reconstruction.
