Arthroscopic therapy of Baker′s cyst with radiofrequency

目的 探讨关节镜监视下射频气化手术治疗窝囊肿的可行性。 方法 2 0 0 0年 2月～ 2 0 0 2年 10月 ,采用局麻关节镜监视下射频气化窝囊肿摘除术 2 1例。年龄 4 5～ 6 6岁。窝囊肿伴有膝关节骨性关节炎 18例、半月板损伤 3例。术前行CT扫描 11例、MRI检查 8例、囊肿造影 5例、B超 2例 ,观察囊肿与周围组织的解剖关系。镜视下将含有肾上腺素的生理盐水注入囊壁脏层组织 ,采用囊外剥离和囊内射频气化切割处理囊壁组织。 结果 术后随访 2 1例 ,无感染和血管神经损伤 ,疗效满意。术后复发 3例 ,其中 2例关节镜清理术后痊愈 ,1例保守治疗。 结论 局麻关节镜监视下窝囊肿切除术方法可行 ,安全可靠 。

Objective To explore the feasibility of arthroscopic therapy of Baker′s cysts with radiofrequency. Methods Since Feb. 2000 to Oct. 2002 a surgical arthroscopic treatment for popliteal cyst in a series of 21 patients. Men 14 and female 7, the age from 45 to 66 year. To do CT scan 11 and MR in 8. To insert a arthroscope to Baker′s cyst, and inject salline in the visceral layer of capsule under the arthroscope, so that remove of the capsule easily. The radiofrequncy to clear the capsule of cyst and hemostasia. Results All of the cases studied, a connection between joint space and cyst was found in 13 cases. The popliteal cyst was found to be almost invariably associated with other knee disorders. Follow up in all of the case. No nerve and blood vessel injure, no infection in this group. The function is well include 3 cases relapsed after re oparetion by arthroscope debridement. Conclusions Surgical arthroscopic therapy of Baker′s cysts is safety and reliable; To removal of capsule integrity and repair of all intraarticular lesions and sealing of the junction between Baker′s cyst and the dorsal recessus of the knee joint for preventing recurrent are very important.
