Intraarticular ganglion cyst arising from the cruciate ligament is difficult to diagnose by clinical symptom. In our case, Cyst attached anteriorly to posterior cruciate ligament, and limited both flexion and extension of knee. The cyst was excised in a piecemeal fashion arthroscopically. Knee pain and limitation in knee motion disappeared by the day after surgery. We hypothesize that reason of restriction of extension is impingement between anterior cruciate ligament and intracondylar, and reason of restriction of flexion is stimulation nerve ending in the synovial membrane stretched with knee motion.
源于交叉韧带的关节内腱鞘囊肿很难通过临床症状诊断。在我们的病例中，囊肿附着于后交叉韧带前方，限制了膝关节的屈伸。通过关节镜以分块方式切除了囊肿。术后第二天膝关节疼痛和活动受限消失。我们推测伸展受限的原因是前交叉韧带与髁间之间的撞击，而屈曲受限的原因是随着膝关节活动而拉伸的滑膜中的神经末梢受到刺激。
