超越ACL：斜坡撕裂对膝关节稳定性的隐匿影响
简介
内侧半月板ramp lesion是前交叉韧带（ACL）损伤中导致膝关节不稳的关键但常被忽视的因素。近年影像与关节镜技术进步提高了其检出率与分型准确性。研究表明，未处理的ramp lesion会持续加重不稳并改变膝关节生物力学，需制定个体化治疗方案。虽多种关节镜修复技术被提出，但最佳术式仍有争议。后内侧入路可提供更佳视野与可靠修复，应用日益广泛。本文综述了ra…
英文摘要
Medial meniscus ramp lesions have emerged as a critical but frequently overlooked contributor to knee instability, particularly in the context of anterior cruciate ligament (ACL) injuries. Recent advances in imaging and arthroscopic techniques have improved their detection and classification, enhancing our understanding of their anatomical and functional significance. Evidence indicates that untreated ramp lesions may perpetuate instability and alter knee biomechanics, underscoring the need for structured, individualized treatment. Although multiple arthroscopic repair strategies have been proposed, the optimal technique remains debated. The posterior portals approach offers superior visualization and reliable repair, and has gained increasing adoption. This review synthesizes current insights into ramp lesion pathophysiology, classification, diagnostic advances, and evolving management strategies, emphasizing the importance of accurate identification and tailored intervention to optimize patient outcomes.
