We read with interest the recently published article titled, “Ultrasound Imaging of the Posterior Cruciate Ligament and its Mimic, the Posterior Meniscofemoral Ligament” by Ke-Vin Chang et al.¹ We appreciate the authors for raising the attention on the posterior meniscofemoral ligament (PMFL) which is an important but frequently neglected structure for the stability of the posterior knee and the lateral meniscus. Herein, we would like to share our opinions regarding the sonoanatomy of this ligament, which would replenish this clinically important article.

致编辑的信：对“后交叉韧带及其模拟物，半月板后韧带的超声成像”的评论

我们感兴趣地阅读了 Ke-Vin Chang 等人最近发表的题为“后交叉韧带及其模拟物，半月板后韧带的超声成像”的文章。¹我们感谢作者提高对后半月板韧带 (PMFL) 的关注，这是一个重要但经常被忽视的结构，用于稳定膝后部和外侧半月板。在此，我们想分享我们对这条韧带的声波解剖学的看法，这将补充这篇临床上重要的文章。
