Clinical application of MRI measurements in knee joint meniscus / 局解手术学杂志

ABSTRACT

Objective To measure the scope of normal meniscus by magnetic resonance imaging(MRI),and create a database of meniscus size of each part.Methods The MRI image measured rake angle and back angle,body height and width of each part and the angular distance of rake and back angle of 303 meniscus of normal knee joint.Results The width and height of anterior horn,anterior exterior angle,body,angulus posteriolateralis and back angle of the medial meniscus were (5.67 ± 1.37) mm and (3.53 ± 0.86) mm,(7.24 ± 1.91) mm and (4.38 ±1.01) mm,(5.61 ± 1.73)mm and (4.25 ±1.07) mm,(11.01 ±3.53) mm and (5.41 ± 1.66)mm,(9.21 ±2.71)mm and (5.02 ± 1.39)mm,respectively.Rake and back angle of angular distance was (38.51 ± 10.88)mm.The width and height of the anterior horn,anterior exterior angle,body,angulus posteriolateralis and back angle of the lateral meniscus were (6.95 ± 1.69) mm and (3.83 ± 0.91) mm,(7.48±1.90)mmand (4.06 ± 0.97) mm,(6.51± 1.79) mm and (5.10±1.01)mm,(7.62±1.99)mm and (5.18±1.19)mm,(6.68 ± 1.41) mm and (5.64 ± 1.12) mm,respectively.The rake and back angle of angular distance was (38.51 ± 10.88) mm.Conclusion In this study,we obtained the data of meniscus for normal people by MRI,which provides reference values for diagnosis of meniscus injury and transplantation.
