The anterior and posterior cruciate ligaments are crucial stabilizers of the knee. These ligaments are named by the location of their tibial attachments. Each ligament is composed of separate functional bundles that differ in size but are equally important in function. MR imaging is accurate and sensitive, making it the imaging technique of choice for evaluating these ligaments. Acute and chronic injuries involving the cruciate ligaments have typical appearances and associated findings. MR imaging interpretation must take into account atypical injuries and imaging pitfalls. Knowledge of normal ligament reconstruction techniques allows differentiation of the normal postoperative appearance from reconstruction failure and complications. Ligament reconstruction techniques, complications, and appearances are reviewed in this article.
前交叉韧带和后交叉韧带是膝关节的关键稳定结构。这些韧带根据其在胫骨附着点的位置命名。每条韧带均由不同大小但功能同等重要的独立功能束组成。磁共振成像（MR成像）准确且敏感，使其成为评估这些韧带的首选成像技术。涉及交叉韧带的急性和慢性损伤具有典型表现及相关征象。MR成像解读必须考虑非典型损伤及成像陷阱。了解正常韧带重建技术有助于区分正常术后表现与重建失败及并发症。本文对韧带重建技术、并发症及表现进行了综述。
