Cysts associated with the cruciate ligaments are rare with an incidence of less than 1%. Most are asymptomatic and detected as incidental findings, but some are symptomatic presenting with knee pain and restricted range of motion. . A 33-year-old female presented with pain and restriction of terminal flexion at the knee. No history of trauma was present. Clinically no diagnosis could be established. MRI showed a cyst located between the femoral attachments of cruciate ligaments which was further confirmed by diagnostic arthroscopy. Rupture of the cyst was done arthroscopically. Postoperatively, patient was relieved of the pain. There were no subsequent recurrences.
Cysts between the cruciate ligaments must be kept as a differential while dealing with a patient of knee pain, with no antecedent history of trauma and where clinically no diagnosis can be made. Arthroscopic excision or rupture has a good success rate with no recurrences.
与交叉韧带相关的囊肿很少见，发病率低于1%。大多数囊肿无症状，为偶然发现，但有些囊肿有症状，表现为膝关节疼痛和活动范围受限。一名33岁女性因膝关节终末屈曲疼痛和受限前来就诊。无外伤史。临床无法确诊。磁共振成像（MRI）显示囊肿位于交叉韧带的股骨附着点之间，诊断性关节镜检查进一步证实了这一点。通过关节镜对囊肿进行了破裂处理。术后患者疼痛缓解。无后续复发情况。
在处理无外伤史且临床无法确诊的膝关节疼痛患者时，必须将交叉韧带之间的囊肿作为鉴别诊断之一。关节镜下切除或破裂的成功率很高，且无复发情况。
