The anatomy of 1000 symptomatic meniscus lesions is described and related to the age of the patients. All symptomatic lesions found during the study period were treated by arthroscopic surgery. Meniscal lesions were commoner in the right knee (56.5%) and 81% of the patients were men. Of the medial meniscus tears, 75% were vertical and 23% horizontal. Vertical tears of the medial meniscus occurred most often in the fourth decade and horizontal tears in the fifth. There were 22% type I, 37% type II and 31% type III vertical tears; 62% of type I tears and 23% of type II tears had locked fragments. Superior flaps were six times more common than inferior flaps. Of all medial meniscus fragments, 6% were inverted; 51% of these were flaps and the rest ruptured bucket-handle fragments. Of the lateral meniscus lesions 54% were vertical tears, 15% oblique, 15% myxoid, 4% were inverted and 5% were lesions of discoid menisci. The commonest pattern of tear in the lateral compartment (27%) was a vertical tear involving half the length and half the width of the meniscus.
描述了1000例有症状的半月板损伤的解剖结构，并将其与患者年龄相关联。研究期间发现的所有有症状的损伤均通过关节镜手术治疗。半月板损伤在右膝更为常见（56.5%），81%的患者为男性。内侧半月板撕裂中，75%为垂直撕裂，23%为水平撕裂。内侧半月板垂直撕裂最常发生在第四个十年，水平撕裂发生在第五个十年。垂直撕裂中，I型占22%，II型占37%，III型占31%；I型撕裂中有62%和II型撕裂中有23%有锁定碎片。上瓣比下瓣常见六倍。在所有内侧半月板碎片中，6%为翻转；其中51%为瓣状，其余为破裂的桶柄状碎片。外侧半月板损伤中，54%为垂直撕裂，15%为斜形撕裂，15%为黏液样撕裂，4%为翻转，5%为盘状半月板损伤。外侧半月板最常见的撕裂模式（27%）是垂直撕裂累及半月板长度的一半和宽度的一半。
