Anterior cruciate ligament (ACL) reconstruction with internal bracing (IB)-and ACL repair with IB when indicated-reduces graft or repair failure. IB is safe and protects ligament reconstructions and repairs. The IB construct should not be misunderstood as a synthetic ligament. To be effective, suture tape must be independently secured with the knee in full extension, reflecting the terminal length of the ACL. Regardless of graft type, the graft must be cyclically tensioned independent of the IB to allow for creep, and when properly performed, this significantly increases the ultimate tensile strength of the construct and reduces graft elongation, without stress shielding. Thus, the generic term "suture augmentation" may be misleading because the successful results reported apply to the IB technique. In our experience, the failure rate after ACL reconstruction with IB is 1% at the 5-year follow-up period. Notably, these results were achieved without an additional lateral extra-articular procedure.
前交叉韧带(ACL)重建结合内部支撑(IB)-以及当需要时的 ACL 修复结合 IB-可降低移植物或修复失败的风险。IB 是安全的,并能保护韧带重建和修复。IB 结构不应被误解为合成韧带。为了有效,缝线带必须在膝关节完全伸展的情况下独立固定,反映 ACL 的末端长度。无论移植物类型如何,移植物都必须在不受 IB 影响的情况下周期性地张紧,以允许蠕变,并且当正确执行时,这会显著增加结构的最终拉伸强度并减少移植物伸长,而不会产生应力屏蔽。因此,通用术语“缝线增强”可能会产生误导,因为报告的成功结果适用于 IB 技术。根据我们的经验,在 5 年随访期间,使用 IB 进行 ACL 重建的失败率为 1%。值得注意的是,这些结果是在没有额外的外侧关节外手术的情况下实现的。
