Fifty-two children with 62 discoid lateral menisci were reviewed at an average follow-up of 5.5 years. Their average age at operation was 10.5 years and the mean delay in diagnosis was 24 months. Most of the children had vague and intermittent symptoms and the classical clunk was demonstrable in only 39% of the knees. An associated osteochondritis dissecans of the lateral femoral condyle was seen in seven knees. Forty-eight knees with symptomatic torn discoid menisci underwent open total lateral meniscectomy, six had arthroscopic partial meniscectomy and eight knees with intact discoid menisci, were left alone. Based on Ikeuchi's grading (Ikeuchi 1982), 37% of the knees had an excellent result, 47% had a good result and 16% had a fair result: none was poor. Arthroscopic partial meniscectomy is recommended only when the posterior attachment of the discoid meniscus is stable. A total meniscectomy is indicated for the Wrisberg-ligament type of discoid meniscus with posterior instability.
对52例患有62个盘状外侧半月板的儿童进行了回顾性研究，平均随访时间为5.5年。他们手术时的平均年龄为10.5岁，平均诊断延迟为24个月。大多数儿童有模糊和间歇性症状，只有39%的膝关节可出现典型的“咯嗒”声。7个膝关节伴有外侧股骨髁剥脱性骨软骨炎。48例有症状的盘状半月板撕裂膝关节接受了开放性全外侧半月板切除术，6例进行了关节镜下部分半月板切除术，8例盘状半月板完整的膝关节未作处理。根据池内分级（池内，1982年），37%的膝关节结果为优，47%为良，16%为可：无差的结果。仅当盘状半月板后附着稳定时，才建议进行关节镜下部分半月板切除术。对于具有后向不稳定的Wrisberg韧带型盘状半月板，应行全半月板切除术。
