Although popliteal cysts are most frequently identified in patients with osteoarthritis (OA), they may occur in patients with rheumatoid arthritis (RA), in which serious complicated cases such as cyst rupture can be developed. The objective of this study was to report four patients with RA (six knees) in combination with OA with a brief review of literature of previous similar published cases. This is a retrospective review of case records of patients with refractory and/or complicated popliteal cysts, who have successfully treated with arthroscopic intervention. We suggest that arthroscopic interventions such as radical debridement, synovectomy, biomechanical valve excision, and/or cystectomy should be considered in patients with refractory and complicated popliteal cysts associated with RA or RA in combination with OA.

关节镜成功治疗风湿性关节炎合并骨关节炎的难治性和复杂的lite肿囊肿：病例系列及文献复习。

尽管pop骨囊肿最常在骨关节炎（OA）患者中发现，但它们可能发生在类风湿关节炎（RA）患者中，在这种情况下，可能会出现严重的复杂病例，例如囊肿破裂。这项研究的目的是报告4例RA（6膝）合并OA的患者，并简要回顾以前相似病例的文献。这是回顾性审查的难治性和/或复杂的pop窝囊肿患者的病例记录，这些患者已通过关节镜干预成功治疗。我们建议对于难治性和复杂性pop总囊肿合并RA或RA合并OA的患者，应考虑进行根治性清创，滑膜切除术，生物力学瓣膜切除和/或膀胱切除术等关节镜干预。
