BACKGROUND
There are several reports on anatomical differences of the meniscus. However, there are only a few reports on abnormalities in both menisci and anatomical differences in anterior cruciate ligament insertions.
CASE PRESENTATION
This is a case report of a 36-year-old Hispanic man presenting symptoms, including knee pain, locking, and effusion, with an anatomical abnormality of the menisci corresponding to the fusion of the posterior horns of the menisci in tandem with the insertion of the posterior meniscus fibers in the anterior cruciate ligament.
CONCLUSIONS
This is the first study describing a meniscus anatomical variant with isolated posterior junction of the posterior horn with an anomalous insertion to the anterior cruciate ligament. The recognition of meniscus variants is important as they can be misinterpreted for more significant pathology on magnetic resonance images.
背景
有几篇关于半月板解剖差异的报道。然而，关于双侧半月板异常及前交叉韧带附着处解剖差异的报道却很少。
病例介绍
本文报告了一名36岁西班牙裔男性的病例，该患者出现膝关节疼痛、交锁和积液等症状，其半月板存在解剖学异常，表现为半月板后角融合，同时后半月板纤维附着于前交叉韧带。
结论
这是第一项描述半月板解剖变异的研究，该变异表现为后角孤立的后部连接，并异常附着于前交叉韧带。认识半月板变异很重要，因为在磁共振成像上它们可能被误诊为更严重的病变。
