Abstract
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.
