采用空心韧带增强系统联合半腱肌自体移植物行前交叉韧带重建并联合股薄肌加强前外侧复合体
简介
该文介绍一种ACL重建联合前外侧复合体（ALC）增强的改良技术，采用空心LARS韧带联合半腱肌和股薄肌自体移植物。该术式可减少自体肌腱取材量、降低神经血管损伤风险，并借助LARS的结构支撑即刻恢复膝关节旋转稳定性，利于术后早期活动。此方法尤其适用于自体肌腱较细、高运动需求或ACL翻修患者，但存在股骨定位误差风险且学习曲线较陡。
英文摘要
This technical note describes an alternative surgical technique for anterior cruciate ligament (ACL) reconstruction combined with anterolateral complex (ALC) augmentation. The procedure uses a hollow ligament advanced reinforcement system (LARS), along with semitendinosus and gracilis tendons as grafts. Key surgical steps include arthroscopic exploration, graft preparation, tunnel drilling, and fixation. This technique reduces autologous tendon harvesting, reduces the risk of neurovascular injury, and facilitates immediate restoration of knee rotational stability with early postoperative mobilization. Nonetheless, potential limitations include the possibility of femoral positioning errors and a relatively steep learning curve. This method is particularly suitable for patients with thin autologous tendons, high athletic demands, or those undergoing revision ACL surgery, as it can augment smaller autologous grafts and confer immediate mechanical strength via the structural support of the hollow LARS ligament, thereby helping to maintain knee stability in the early postoperative period.
