从70例年龄小于55岁的尸检受试者的膝关节中取出半月板，18.6%的受试者显示至少1个水平劈裂病变; 200例尸检受试者中7%的受试者显示至少1个盘状外侧半月板。这表明，无论是这些或水平卵裂病变引起的症状，在每个受试者的一生。在76%的大体正常的内侧半月板检查中观察到变性的显微镜迹象。内侧髁的表面积比外侧髁大，并且在后方更宽、更厚。后内侧半月板厚度越大，可能使其更脆弱，因为滑液的营养扩散越少。
The Menisci were removed from knees of 70 autopsy subjects less than 55 yr old, and 18.6% exhibited at least 1 horizontal cleavage lesion; 7% of 200 autopsy subjects showed at least 1 discoid lateral meniscus. It is suggested that neither these nor horizontal cleavage lesions had caused symptoms during each subject''s lifetime. Microscopic signs of degeneration were seen in 76% of grossly normal medial menisci examined. Medial menisci have a larger surface area than lateral menisci and are broader and thicker posteriorly. The greater thickness of the medial meniscus posteriorly may render it more vulnerable because there is less nutritional diffusion of synovial fluid.
