在一组高性能举重运动员的交叉韧带（CL）的横截面积增加值进行了观察。这项研究的目的是调查如果重复的重锻炼增加这些结构的体积。膝关节检查采用1.5T MRI系统。在一组9名运动员的T1加权成像中，对前交叉韧带（ACL）和后交叉韧带（PCL）中间物质横截面的面积进行了评价。19名参与者的对照组也使用相同的协议进行了检查。两组间ACL和PCL中间体横截面积存在显著差异。CL的中间体的面积和训练的开始呈强负相关，PCL的横截面积与训练的持续时间呈强正相关。这项研究是第一次描述的CLs肥大，这可能是由大负荷训练，开始约青春期的年龄。训练开始的年龄似乎比训练持续时间对肥大过程有更大的影响。了解交叉韧带过度生长现象对于骨科至关重要，因为CL的机械性能和三维方向可能发生的变化可能会影响创伤的发生率和重建手术技术。
In a group of high performance weightlifters increased values of the cruciate ligaments (CLs) cross-sectional areas were observed. The purpose of this research was to investigate if repeated heavy workouts increase the volume of those structures. The knee examinations were performed with an 1,5T MRI system. The area of the anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL) midsubstance cross-section were evaluated in T1-weighted images with administration of contrast medium in a group of nine athletes. A control group of 19 participants was also examined using the same protocol. Significant differences of the ACL and the PCL midsubstance cross-sectional areas were observed between groups. The area of the CLs' midsubstance and the onset of training were strongly negatively correlated and the PCL cross-sectional area was strongly positively correlated with the duration of training. This research is the first description of the CLs hypertrophy, which is probably caused by heavy training that was started about the age of puberty. The age of training onset seems to have a greater impact on the hypertrophy process than the training duration. Knowledge of the phenomenon of cruciate ligament overgrowth is vital for orthopaedics because, possible changes of the CLs mechanical properties and three-dimensional orientation, may affect the incidence of trauma and reconstruction procedures technique.
