半月板弯斜段损伤的研究进展

Research development in ramp lesion of meniscus

摘要:

半月板弯斜段损伤是一种与前交叉韧带撕裂密切相关的特殊类型损伤，涉及内侧半月板后角红-红区至后内侧关节囊的移行区。随着对其解剖、损伤机制和生物力学认识的不断深入，人们认识到弯斜段损伤将严重影响膝关节稳定性，未经及时治疗常导致前交叉韧带重建失败。通过MRI 和关节镜检查等手段可明确弯斜段损伤的诊断及分型并制定相应的手术方案。通过手术修复病变并遵循适当的康复方案，可显著改善主观膝关节评分，增加膝关节稳定性，并提高愈合率。本文就半月板弯斜段损伤的近期研究进展进行综述，为临床诊治提供参考。

Abstract:

Ramp lesion of meniscus is a special type of injury closely related to the tear of anterior cruciate ligament, involving thetransition 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 stabilityof 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 kneejoint 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 oframp lesion in order to provide reference for clinical diagnosis and treatment.
