The purpose of this study was to evaluate anterior cruciate ligament (ACL) function in knee osteoarthritis (OA) and clarify the relationship of MRI and arthroscopic findings with ACL function. Eighty patients with knee OA were evaluated for anterior knee joint laxity, Kellgren-Lawrence grade, MRI ACL grade, arthroscopic ACL grade, osteophytes, and meniscus tears. ACL function was significantly correlated with osteophyte scores and medial and lateral meniscus tears. The MRI ACL grade was strongly correlated with the arthroscopic ACL grade, and anterior knee joint laxity decreased as the grades increased, suggesting a decrease in the elasticity of degenerated ACLs.
本研究的目的是评估膝关节骨关节炎（OA）中前交叉韧带（ACL）的功能，并阐明MRI和关节镜检查结果与ACL功能的关系。对80例膝关节OA患者进行了膝关节前侧松弛度、Kellgren-Lawrence分级、MRI ACL分级、关节镜下ACL分级、骨赘和半月板撕裂的评估。ACL功能与骨赘评分以及内侧和外侧半月板撕裂显著相关。MRI ACL分级与关节镜下ACL分级密切相关，并且随着分级增加膝关节前侧松弛度降低，提示退变的ACL弹性下降。
