Discoid lateral meniscus has been described as a morphologically variable anomaly, and several classifications have been proposed. We have seen twelve patients with the so-called complete type of discoid lateral meniscus, with intact ligament attachments as an incidental finding at the time of arthroscopy. Ten of the twelve patients were without significant symptoms attributable to the meniscus; that is, they had no meniscal tears or laxity. We also have seen six patients with the Wrisberg-ligament type of discoid lateral meniscus, in which there is abnormal meniscal mobility. All six patients were symptomatic and had the so-called snapping-knee syndrome, for which they had arthroscopic lateral meniscectomy. During arthroscopy, care should be taken not to confuse the asymptomatic complete type of discoid lateral meniscus with the Wrisberg-ligament type.
盘状外侧半月板被描述为一种形态多样的异常情况，并且已经提出了几种分类方法。我们在关节镜检查时偶然发现了12例所谓完全型盘状外侧半月板患者，其韧带附着完整。这12例患者中有10例没有可归因于半月板的明显症状；也就是说，他们没有半月板撕裂或松弛。我们还见过6例Wrisberg韧带型盘状外侧半月板患者，其半月板活动异常。所有6例患者都有症状，患有所谓的弹响膝综合征，为此他们接受了关节镜下外侧半月板切除术。在关节镜检查过程中，应注意不要将无症状的完全型盘状外侧半月板与Wrisberg韧带型混淆。
