1·The anterior and posterior cruciate ligaments are intact with normal signal intensity.

前，后十字韧带完好无损正常的信号强度。

2·RESULTS: the repair materials for the reconstruction of cruciate ligaments of the knee joint mainly include autograft, allograft and artificial ligament.

结果：膝关节交叉韧带的重建修复材料主要有包括自体移植物、同种异体移植物和人工韧带。

3·Objective To discuss the clinical results of arthroscopic reconstruction of posterior and anterior cruciate ligaments of the knee with double semitendinous tendons.

目的观察膝关节镜下双股半腱肌腱单端固定法重建膝前、后交叉韧带的方法及疗效，探讨其优缺点。

4·The unclear image due to the overlapped skeletal images around the knee often influence the diagnosis of the tibial-attachment fracture of the anterior and posterior cruciate ligaments of the knee.

对膝关节前后十字韧带胫骨止点骨折，常因关节周围骨骼影像重叠使其显影不清而影响诊断。

5·Objective To provide an anatomic evidence for the posterior cruciate ligament(PCL) reconstruction, the role of its sub-bundles and the function of the meniscofemoral ligaments were studied.

目的：探讨后交叉韧带分束情况及板股韧带的作用，为临床重建后交叉韧带提供解剖学基础。
