关节镜下清理术结合囊肿-关节腔交通口扩大术治疗腘窝囊肿

Arthroscopic treatment of popliteal cyst with intra-articular debridement and enlargement of the connecting hole between popliteal cyst and joint cavity

目的探讨关节镜下清理术结合囊肿-关节腔交通口扩大术治疗腘窝囊肿的效果。方法对12例腘窝囊肿患者行关节镜下清理术结合囊肿-关节腔交通口扩大术。手术前后采用Lysholm膝关节功能评价、Rauschning和Lindgren分级方法和膝关节MRI进行评估。结果12例均获随访,时间12-23（16±4）个月,Lysholm评分术前为（55.8±3.7）分,术后6个月为（82.1±4.2）分,差异有统计学意义（P〈0.05）,Rauschning和Lindgren分级术前为1级1例,2级1例,3级10例,术后6个月为1级11例,2级1例。所有患膝运动能力均较术前有所改善。结论关节镜下清理术结合囊肿-关节腔交通口扩大术治疗腘窝囊肿具有创伤小、康复快、复发率低的优点。

Objective To evaluate the results of arthroscopic treatment of popliteal cyst with intra-articular debridement and enlargement of the connecting hole between popliteal cyst and joint cavity.Methods 12 patients with popliteal cyst were treated by arthroscopy.During operation,the intra-articular pathology was corrected and the connecting hole between popliteal cyst and joint cavity were enlarged.The patients were followed up and evaluated according to Lyscholm rating scale and the guidelines of Rauschning and Lindgren.The magnetic resonance image of the knee joint was done on the patients before and after operation.Results All 12 patients were followed up from 12 to 23（16±4）months.The Lysholm knee score were（55.8±3.7） preoperatively and（82.1±4.2） 6 months postoperatively.There was statistical significance（P〈0.05）.According to the guidelines of Rauschning and Lindgren,there were 1 case of grade Ⅰ,1 grade Ⅱ and 10 grade Ⅲ preoperatively.And there were 11 cases of grade Ⅰ and 1 cases of grade Ⅱ 6 months postoperatively.The sport ability was improved in all cases.Conclusions The arthroscopic treatment of secondary popliteal cyst with intra-articular debridement and enlargement of the connecting hole between popliteal cyst and joint cavity have the advantages of mini-invasive,fast-recovery,and low recurrence rates.
