With increased use of magnetic resonance imaging (MRI) and arthroscopy, intra-articular ganglion cysts of the posterior cruciate ligament (PCL) have received more recognition as a possible cause of knee discomfort. Reported treatment options have ranged from ultrasound-guided cyst aspiration to arthroscopic cyst resection. In this report, we present the case of a patient who, on MRI, was diagnosed with a symptomatic intrasubstance PCL ganglion that later, during surgery, demonstrated mucinous degeneration of the entire ligament. Treatment was complete resection of the PCL. Five years after surgery, the patient demonstrated excellent, asymptomatic knee function. Although the best treatment for an intrasubstance PCL ganglion cyst that has caused degeneration of the entire ligament is unknown, PCL resection without reconstruction should be considered a viable option. It can result in a large increase in range of motion and function.
随着磁共振成像（MRI）和关节镜检查的使用增加，后交叉韧带（PCL）关节内腱鞘囊肿作为膝关节不适的可能原因已得到更多认识。报道的治疗选择范围从超声引导下囊肿抽吸到关节镜下囊肿切除。在本报告中，我们介绍了一名患者的病例，该患者在MRI上被诊断为有症状的韧带实质内PCL腱鞘囊肿，后来在手术中发现整个韧带出现黏液样变性。治疗方法是完全切除PCL。术后五年，患者膝关节功能良好，无症状。虽然对于已导致整个韧带变性的韧带实质内PCL腱鞘囊肿的最佳治疗方法尚不清楚，但不进行重建的PCL切除应被视为一种可行的选择。它可导致活动范围和功能大幅增加。
