Discoid lateral meniscus in the knee joint is common. From July 1990 through September 1992, the authors performed arthroscopy on 534 symptomatic knee joints. Seventy-seven knees of 72 patients had discoid lateral meniscus. Of the 77 knees treated, 4 (5.5%) had discoid lateral meniscus associated with anomalous insertion of the anterior horn of the medial meniscus into the anterior cruciate ligament. The discoid lateral meniscus was reshaped in the 4 knees, and followup was done from 12 to 24 months (average, 20 months) after surgery. The results were satisfactory, except for 1 patient who damaged his knee in a traffic accident. The authors concluded that this anatomic variant of the medial meniscus was not related to the patients' symptoms, but that reshaping the discoid lateral meniscus did relieve their symptoms.
膝关节盘状外侧半月板很常见。1990年7月至1992年9月，作者对534例有症状的膝关节进行了关节镜检查。72例患者的77个膝关节存在盘状外侧半月板。在接受治疗的77个膝关节中，4个（5.5%）的盘状外侧半月板伴有内侧半月板前角异常插入前交叉韧带。对这4个膝关节的盘状外侧半月板进行了重塑，并在术后12至24个月（平均20个月）进行了随访。结果令人满意，只有1例患者在交通事故中膝关节受伤。作者得出结论，内侧半月板的这种解剖变异与患者症状无关，但重塑盘状外侧半月板确实缓解了他们的症状。
