关节镜下治疗胭窝囊肿32例分析

目的探讨关节镜下治疗胴窝囊肿的方法及临床疗效。方法对本组32例有膝关节症状、B超提示囊肿与后关节囊相通的胭窝囊肿患者，采用关节镜技术同期行膝关节清理与后内侧间室扩大胭窝囊肿与关节腔之间的通道口，其中6例巨大囊肿（直径〉5cm）同时行后路关节镜下囊壁切除术。根据Rauschning和Lindgren分级方法评定手术疗效。结果32例患者关节镜检查均可发现伴有关节内病变，28例患者术后获得随访，随访时间为6～29个月，平均11个月。其中有2例复发，为严重的骨关节炎患者，采用全膝关节置换术后痊愈。Rauschning和Lindgren分级结果：术前Ⅱ级24例，Ⅲ级8例；术后0级26例，Ⅰ级4例，Ⅱ级2例。结论关节镜下治疗窝囊肿具有创伤小、恢复快、复发率低的优点。

Arthroscopic treatment of popliteal cyst in 32 patients

Objective To discuss the techniques and efficacy of arthroscopic surgery treatment for popliteal cyst.Methods From February 2005 to May 2008, 32 patients of knee osteoarthritis with popliteal cyst were diagnosed by ultrasonograph and treated with arthroscopy. During operation, the intra-articular pathology was corrected and the connecting hole between popliteal cyst and joint space were enlarged. The capsule was removed in 6 large cysts(about 5 cm in diameter) under arthroscopy. Results Arthroscopic examinations showed evident pathological changes in the knee joints of the 32 patients. Of all the 32 cases, 28 cases were followed up from 6 to 29 months. The recurrence of popliteal cyst in 2 cases was involved in severe knee osteoarthritis. According to the Rauschning and Lindgren Grading, 24 patients were grade Ⅱand 8 were grade Ⅲ before the operation. After the operation, 26 patients were grade 0, 4 were gradeⅠ, and 2 was grade Ⅱ.Conclusions The arthroscopic treatment of popliteal cyst has the advantages of mini-invasive, fast-recover, and low recurrence.
