The authors present a case of a 41-year-old woman who was treated for a chronic type 2 posterior horn tear of the medial meniscal root. During an arthroscopic repair, a broad, thick ligament coursing through the intercondylar notch caused difficulty in visualizing the posterior joint space and necessitated creation of an accessory portal. Given its course and attachments, this structure was an example of a rare variant of anatomy, an oblique meniscomeniscal ligament.
An oblique meniscomeniscal ligament may complicate surgery in the posterior knee by presenting a visual and physical impediment to the surgeon.
作者报告了一例 41 岁女性慢性 2 型后角内侧半月板根撕裂的病例。在关节镜修复过程中，一条宽阔、厚实的韧带穿过髁间切迹，导致难以观察到后关节间隙，需要创建一个辅助入路。鉴于其走行和附着，该结构是一种罕见的解剖变异，即斜半月板半月板韧带的例子。
斜半月板半月板韧带可能会通过对术者造成视觉和物理上的阻碍，从而使后膝关节手术复杂化。
