编辑评论：许多ramp lesion似乎在ACL重建术前已愈合
简介
这篇编辑评论指出，术前MRI发现的ramp lesion远多于ACL重建术中关节镜所见，相关临床研究显示稳定撕裂不修复与修复的临床结局相当。摘要据此认为，许多ramp lesion可能在ACL重建前已愈合，撕裂稳定性决定是否需经髁间窝观察并建立后内侧入路。
英文摘要
Medial meniscus ramp lesions disrupt meniscocapsular and/or meniscotibial interconnections, exacerbating translational and rotational instability in the anterior cruciate ligament-deficient knee. The difficulty in directly visualizing this region of the meniscus has led some to advocate for routine viewing through the intercondylar notch and probing/debridement of the posterior horn through a posteromedial portal. A growing number of studies show that far more ramp lesions are seen on preoperative magnetic resonance imaging than are found at the time of arthroscopy, and clinical studies show equivalent clinical outcomes to repair when stable tears are left unrepaired. It seems likely that many ramp lesions heal and that stability of the tear dictates the need for intercondylar notch viewing and establishment of a posteromedial portal.
