To reduce the damage to posteromedial knee capsule, we developed a direct extra-articular arthroscopic approach for excision of symptomatic popliteal cysts. This study aimed to demonstrate the surgical technique and present the 2-year follow-up results. Cystectomy is performed by extra-articular surgical approach through a high posteromedial portal. Twenty-one consecutive patients diagnosed of symptomatic popliteal cysts with failed initial conservative treatments were included. At a median follow-up of 29.4 months, all knees had improved clinical function assessed by Rauschning and Lindgren knee classification (p<0.001). The cysts were either disappeared (95.2%) or reduced in size (4.8%). Only one (4.8%) patient had recurrent cyst, which was solved after ultrasound-guided aspiration. This direct extra-articular arthroscopic technique could be a feasible alternative for treatment of symptomatic popliteal cysts.
为了减少对膝关节后内侧囊的损伤，我们开发了一种直接的关节外关节镜入路，用于切除有症状的腘窝囊肿。本研究旨在展示手术技术并介绍 2 年随访结果。囊肿切除术通过高后内侧入路进行关节外手术。连续纳入 21 例经初次保守治疗失败的有症状腘窝囊肿患者。中位随访 29.4 个月时，所有膝关节的临床功能均通过 Rauschning 和 Lindgren 膝关节分级得到改善（p<0.001）。囊肿要么消失（95.2%），要么缩小（4.8%）。仅 1 例（4.8%）患者出现复发性囊肿，经超声引导抽吸后得到解决。这种直接的关节外关节镜技术可能是治疗有症状的腘窝囊肿的一种可行的替代方法。
