关节镜下治疗胭窝囊肿的临床分析

目的比较胭窝囊肿关节镜下治疗与开放手术治疗的临床疗效。方法2009年3月至2012年1月，共收治胭窝囊肿患者5l例。按Rauschning和Lindgren胭窝囊肿分级。其中关节镜组27例为采用关节镜下治疗胭窝囊肿，Ⅱ级8例，Ⅲ级19例。开放手术治疗组24例为采用传统开放手术治疗胭窝囊肿，Ⅱ级6例，Ⅲ级18例。比较两组手术切口长度，手术时间，术后恢复至0级的恢复率，囊肿复发率。结果两组患者均获得8～16个月随访，平均13．6个月。切口长度：关节镜组（1．08±0．14）cm明显低于开放手术组（10．08±0．75）cm，差异有统计学意义（P〈0．05）.手术时间：关节镜组（30．25±3．38）min长于开放手术治疗组（19．85±2．32）min，差异有统计学意义（P〈0．05）。术后按Rauschning和Lindgren胭窝囊肿分级，关节镜组：0级24例，Ⅰ级1例，Ⅱ级2例。开放手术组：0级21例，Ⅰ级2例，Ⅱ级1例。恢复率：关节镜组（88．9％）与开放手术组（87．5％）差异无统计学意义（P〉0．05）.复发率：关节镜组（3．7％）与开放手术组f8．3％1，差异无统计学意义（P〉0．05o结论关节镜下治疗胭窝囊肿创伤小、恢复快、疗效确切。

Clinical analysis on arthroscopic treatment of popliteal cysts

Objective To compare the differences in clinical effects between arthroscopic treatment of popliteal cysts and open operation. Methods From March 2009 to January 2012, 51 patients with popliteal cysts were treated. According to Rauschning and Lindgren classification, 27 patients who were treated by arthroscopy was Group A, including 8 cases of grade II and 19 cases of grade III. 24 patients who were treated by traditional open operation was Group B, including 6 cases of grade II and 18 cases of grade III. The incision length, operation time, rate of improving to grade 0 after the surgery and cyst recurrence rate were compared between the 2 groups. Results The patients in both groups were followed up for 13.6 months on average （ range; 8-16 months ）. The incision length of （ 1.08±0.14 ） cm in Group A was obviously lower than （ 10.08±0.75 ） cm in Group B, and the differences were statistically sinificant （ P〈0.05 ）. The operation time of （ 30.25±3.38 ） min in Group A was longer than （ 19.85±2.32 ） min in Group B, and the differences were statistically significant （ P〈0.05 ）. According to Rauschning and Lindgren classification, there were 24 cases of grade 0, 1 case of grade I and 2 cases of grade II in Group A and 21 cases of grade 0, 2 cases of grade I and 1 case of grade II in Group B. There were no statistically significant differences in the improvement rate between Group A （ 88.9% ） and Group B （ 87.5% ） （ P〉0.05 ）. There were no statistically significant differences in the recurrence rate between Group A （ 3.7% ） and Group B （ 8.3% ） （P〉0.05 ）. Conclusions Arthroscopie treatment ofpopliteal cysts is an effective method, with less trauma and early recovery.
