Arthroscopic partial menisectomy followed by cyst decompression is currently recommended for treatment of a meniscal cyst. However, it is doubtful whether partial menisectomy should be performed on cysts communicating with the joint in cases without a meniscal tear on its surface since meniscal function will be sacrificed. In this report, a meniscal cyst arising from the posterior horn of the medial meniscus without meniscal tear on its surface was resected using an arthroscopic posterior trans-septal approach. A 59 year-old male presented to our hospital with popliteal pain when standing up after squatting down. Magnetic resonance imaging revealed a multilobulated meniscal cyst arising from the posterior horn of the medial meniscus extending to the posterior septum with a grade 2 meniscal tear by Mink's classification. The medial meniscus was intact on the surface on arthroscopic examination. The meniscal cyst and posterior septum were successfully resected using a posterior trans-septal approach without harming the meniscus. This is the first report on a meniscal cyst being resected using an arthroscopic posterior trans-septal approach with a 9-month follow-up period.
目前推荐采用关节镜下部分半月板切除术联合囊肿减压术治疗半月板囊肿。然而，对于表面无半月板撕裂但与关节相通的囊肿，是否应进行部分半月板切除术仍存在疑问，因为这样会牺牲半月板功能。在本报告中，我们采用关节镜后经隔膜入路切除了一例源于内侧半月板后角且表面无半月板撕裂的半月板囊肿。一名59岁男性患者因蹲下后站立时腘窝疼痛前来我院就诊。磁共振成像显示一个多叶状半月板囊肿，源于内侧半月板后角，延伸至后隔膜，根据明克分类法为2级半月板撕裂。关节镜检查发现内侧半月板表面完整。采用后经隔膜入路成功切除了半月板囊肿和后隔膜，未损伤半月板。这是首例关于采用关节镜后经隔膜入路切除半月板囊肿并随访9个月的报告。
