To explore the diagnosis and treatment of ganglion cysts of the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) of the knees.
Retrospective analysis of clinical data of patients with ganglion cysts of ACL and PCL as confirmed by arthroscopy and pathology.
All patients were followed up at the clinic in a mean period of 2 years, and their symptoms including arthralgia, swelling and interlocking of the affected knees disappeared. Normal ranges of joint motion were restored successfully.
Ganglion cysts of the cruciate ligaments can easily be detected by MRI and should be arthroscopically resected, not only treated by ultrasound but also by CT-guided paracentesis. Complete resection of the cyst and cyst walls is recommended to avoid recurrence. Positive diagnosis of this disease can be improved by clinical manifestations and specific MRI findings. Trauma and chronic strain were the primary etiological factors responsible for ganglion cysts that were more common in ACL than PCL.
探讨膝关节前交叉韧带（ACL）和后交叉韧带（PCL）腱鞘囊肿的诊断和治疗方法。
对经关节镜和病理证实的 ACL 和 PCL 腱鞘囊肿患者的临床资料进行回顾性分析。
所有患者均在门诊随访 2 年，其关节痛、肿胀和受累膝关节交锁等症状消失，关节活动范围恢复正常。
MRI 易发现此类腱鞘囊肿，应行关节镜下切除，不应仅采用超声或 CT 引导下穿刺抽吸。建议彻底切除囊肿及囊壁，以避免复发。该病的临床和特定 MRI 表现有助于明确诊断。创伤和慢性劳损是导致腱鞘囊肿的主要病因，ACL 比 PCL 更容易发生此类囊肿。
