Ramp lesion of meniscus is a special type of injury closely related to the tear of anterior cruciate ligament,involving the transition area from the red-red zone of the posterior horn of the medial meniscus to the posteromedial joint capsule.With the deepening un-derstanding of its anatomy,injury mechanism and biomechanics,it is recognized that ramp lesion will have a serious impact on the stability of the knee joint.Untreated ramp lesion often leads to the failure of anterior cruciate ligament reconstruction.The diagnosis and classifica-tion of ramp injury can be determined by MRI and arthroscopy,and the corresponding surgical plan can be formulated.The subjective knee joint score can be significantly improved,the stability of the knee joint can be improved and a higher healing rate can be guaranteed by sur-gical repair of the disease and following the appropriate rehabilitation program.This article reviews the recent research development of ramp lesion in order to provide reference for clinical diagnosis and treatment.
