A discoid meniscus is a typical anatomical variation of the knee. There are several cases of either lateral or medial discoid menisci; however, their combination is rare. We describe a rare instance of bilateral discoid medial and lateral menisci.
A 14-year-old boy who developed left knee pain after twisting his knee at school was referred to our hospital. He had limited extension of -10°, lateral clicking, and pain on the McMurray test in the left knee and complained of slight clicks in the right knee. Magnetic resonance imaging results for both knees revealed discoid medial and lateral menisci. Surgery was performed on the symptomatic left knee. Arthroscopically, a Wrisberg-type discoid lateral meniscus and an incomplete-type medial discoid meniscus were confirmed. The symptomatic lateral meniscus was saucerized and sutured and only the asymptomatic medial meniscus was observed. The patient was doing well 24 months after surgery.
We report a rare case of bilateral medial and lateral discoid menisci.
盘状半月板是膝关节典型的解剖变异。外侧或内侧盘状半月板的病例有不少;然而,两者同时存在的情况较为罕见。我们报告一例双侧盘状内侧和外侧半月板的罕见病例。
一名14岁男孩在学校扭到膝盖后出现左膝疼痛,被转诊至我院。他左膝伸展受限达-10°,有外侧弹响,麦氏试验时疼痛,右膝有轻微弹响。双膝磁共振成像结果显示双侧盘状内侧和外侧半月板。对有症状的左膝进行了手术。关节镜检查证实为Wrisberg型外侧盘状半月板和不完全型内侧盘状半月板。对有症状的外侧半月板进行了修整和缝合,仅观察无症状的内侧半月板。术后24个月患者情况良好。
我们报告了一例双侧内侧和外侧盘状半月板的罕见病例。
